Upload your photos → keep their shape with the longest side at 1,600 px, or pad them onto a 1:1 canvas of about 1,600 × 1,600 px, as JPEG, PNG or WebP, each checked against eBay's published 12 MB per-picture limit.

at least one photo that is 500 pixels on the longest side
This is the picture policy's own wording: a listing must include at least one photo that reaches 500 px on its longest side; it is a per-listing floor, not a rule for every photo. Neither preset scales a photo up: the fit-longest preset (the default) leaves a small photo at its own pixel size, and the square preset centres it on the 1,600 × 1,600 canvas at its own pixel size and pads the rest, because enlarging adds no real detail.
Minimum picture size — help page
Should have a minimum resolution of 500 px wide and 500 px high (help page wording)
Images should have a minimum resolution of 500 x 500 pixels but we recommend images that are about 1600 x 1600
The help page words this as a minimum resolution in both dimensions and words it with should, so it is shown here as a recommendation, not as a requirement for every photo. Our research records one hard floor only — the picture policy's per-listing form, at least one photo that is 500 pixels on the longest side — which is the row above.
Images should have a minimum resolution of 500 x 500 pixels but we recommend images that are about 1600 x 1600
A recommendation, not a requirement, and the page's hedge (about) is kept. The fit-longest preset (default) scales the longest side down to 1,600 px and keeps your shape; the square preset pads to an exact 1,600 × 1,600 canvas. Neither preset scales a smaller photo up to fill the canvas — a small original is padded instead. No maximum pixel size appears on the two official pages we checked (adding pictures, picture policy). The only floor either page states is the picture policy's 500 px on the longest side; neither page says how eBay's upload system treats a picture between that floor and the recommended size, and we do not predict it.
Aspect ratio
1:1 or 16:9 (look best in listings, search results and other placements)
Generally, photos in a 1:1 or 16:9 aspect ratio look best in listings, search results, and other placements
Recommendation only (generally … look best). The square preset pads to 1:1 with white; the fit-longest preset leaves the shape unchanged. No 16:9 preset is offered because the official pages give no pixel dimensions for a 16:9 picture and this site does not invent them.
eBay publishes only "12MB each" and does not state decimal or binary; the 12,000,000-byte cap applied here is this page's stricter decimal reading of that wording, not a figure eBay publishes. Every output is checked against that cap: JPEG and WebP outputs reach it by lowering quality as far as 45 (this tool’s own encoder floor, not an eBay figure), and any file still over it — including a PNG, which is written as a 256-colour indexed (palette) PNG and carries no quality slider to lower further — is flagged in its result row rather than shipped silently. This page accepts input files of up to 5 MB each, which is this site's own limit, not an eBay figure.
This tool outputs JPEG (default), PNG or WebP, all on the list. It opens JPEG, PNG, WebP and AVIF files only: GIF, TIFF, BMP and HEIC are accepted by eBay but are reported here as an unsupported file type — an iPhone .heic included. Export a JPEG or PNG from a HEIC original first. An AVIF original opens only if your browser can decode it.
eBay's help page wording is that you can add up to 24 pictures. Our research summary records these 24 as free, but the sentence we captured — "You can add up to 24 pictures" — does not contain that word, so we quote the ceiling and do not claim on this page that the pictures are free. This tool cannot see a listing's picture count in any case: it processes up to 20 images at a time (this tool's own per-run limit, not an eBay figure) and does not track how many pictures a listing already has.
Listed under Not allowed on the picture policy page. This tool does not draw borders and does not check for them. The policy does not say whether flat padding added afterwards counts as a border; if in doubt, use the fit-longest preset (the default), which adds no padding.
Photos with added text, artwork or marketing material
Listed under Not allowed on the picture policy page. This tool does not add or detect text, artwork or marketing material; review your photos before uploading.
Watermarks
Not allowed — watermarks of any type, including those used for ownership attributions
Watermarks of any type, including those used for ownership attributions
Listed under Not allowed on the picture policy page, with the ownership-attribution case called out explicitly. This tool does not add, detect or alter watermarks. We follow the picture policy — treat every watermark as not allowed. Our research notes a second eBay surface, eBay's Seller Center pages, which describe an ownership-watermark allowance. That surface is not an official policy page, we hold no captured wording and no verification date for it, and we publish none of its figures; we follow the picture policy. The full comparison is at /ecommerce-image-spec-conflicts#ebay-watermarks.
What this tool does
Keep your photo's shape and scale the longest side down to 1,600 px (default), or pad it onto a 1:1 canvas of 1,600 × 1,600 px, the size eBay's help page describes as about 1,600 × 1,600 — padding is opt-in because eBay lists photos with added borders as not allowed and does not say whether flat padding counts
Re-encode as JPEG (default), PNG or WebP — all three are on eBay's accepted-format list
Lower JPEG or WebP quality as far as 45 — this tool’s own encoder floor, not an eBay figure — to bring each file within the 12,000,000-byte cap this page applies: eBay publishes only "12MB each" and does not state decimal or binary, so we cap at the stricter decimal reading — our reading of eBay's wording, not an eBay figure; every output is checked against the cap, and any file still over it, including a PNG, which is written as a 256-colour indexed (palette) PNG and carries no quality slider to lower further, is flagged in its result row instead of shipped silently
Composite transparent areas onto white before encoding — every output format, PNG included, is drawn onto an opaque white canvas, so a transparent original comes back with white where it was transparent and a JPEG does not come out with unexpected edges; no eBay rule asks for this, it is how this page works, so keep your original file if you need the alpha channel
Show the output pixel size on every result row, and pad a photo that is smaller than the 1:1 canvas onto it at its own pixel size instead of scaling it up
Strip EXIF, ICC and other metadata as part of re-encoding. JPEG and WebP output is 8-bit RGB; PNG output from this page is an indexed (palette) PNG of at most 256 colours — this tool’s own output, not an eBay figure (neither official page states a bit-depth rule)
Show each rule beside the official eBay page it comes from and the date we last checked it
Process up to 20 images at a time, 5 MB each (this tool's own limits, not eBay figures), all inside your browser
What it does not do
Enlarge a small photo — neither preset scales a photo up: the fit-longest preset (the default) keeps its pixel size, and the square preset centres it on the 1:1 canvas at its own pixel size and pads the rest
Judge whether your listing as a whole meets eBay's minimum picture size — that floor is a per-listing rule, so we flag any single source below 500 px on its longest side but cannot tell you what the other photos in the listing are
Check for, add or alter watermarks, borders or added text — the picture policy lists all of these as not allowed, so review your photos yourself before uploading
Count the pictures on your listing — eBay's help page says you can add up to 24 pictures; this tool works only on the files you give it
Output GIF, TIFF, BMP, HEIC or AVIF — eBay accepts them, but this tool writes JPEG, PNG or WebP only
Read GIF, TIFF, BMP or HEIC input — eBay accepts all four, but this tool opens JPEG, PNG, WebP and AVIF files only, and any other file, an iPhone .heic included, is reported as an unsupported file type. Export a JPEG or PNG from a HEIC original first
Produce a 16:9 canvas — eBay says 1:1 or 16:9 look best but publishes no pixel dimensions for 16:9, so we do not invent one; keep your shape with the fit-longest preset instead
Predict how eBay will treat a listing — we fit the published numbers and link the official pages so you can verify them
Upload your files anywhere
We only crop, resize, re-encode and write metadata. We do not alter the content of your photo. Files are processed in your browser and are not uploaded to a server.
Where the official pages disagree
eBay's two pages word the minimum picture size differently
Images should have a minimum resolution of 500 x 500 pixels but we recommend images that are about 1600 x 1600
How we handle it: The picture policy sets a listing-level floor measured on the longest side; the help page words a per-image minimum in both dimensions, using should. Both are eBay's own. Our research records only one hard floor — at least one photo 500 px on the longest side (picture policy) — so that row is marked required, and the help page's per-image wording is shown as the help page's own wording, not as a per-image requirement. Because the two wordings differ, neither preset turns the minimum into a flag: the output width and height are printed on every result row so you can compare against whichever wording applies to you. We do not decide which page governs; both are linked here.
Numbers you may have seen elsewhere that are not on the official page
eBay allows an ownership watermark as long as it is small and semi-transparent.
The picture policy page linked under Sources lists watermarks of any type, including those used for ownership attributions, under Not allowed, with no size or opacity exception. Our research notes a second eBay surface, eBay's Seller Center pages, which describe an ownership-watermark allowance; that surface is not an official policy page, we hold no captured wording and no verification date for it, and we publish none of its figures. We follow the picture policy. Official page: www.ebay.com
eBay requires a plain white product background.
Neither official page this tool cites — the picture policy or the adding-pictures help page — states any rule about backdrop colour. The picture policy's Not allowed list covers added borders, added text, artwork or marketing material, and watermarks of any type, and says nothing about the colour behind the product. The white this page uses to pad the 1:1 preset, and to composite transparent areas before encoding, is this site's own default, not an eBay rule. Official page: www.ebay.com
FAQ
What picture size does eBay recommend?
eBay's adding-pictures help page says images should be at least 500 px wide and 500 px high and recommends images that are about 1,600 × 1,600 px. The picture policy adds that a listing needs at least one photo of 500 px on its longest side. The 1,600 × 1,600 figure is worded as a recommendation (about), not a requirement; the only floor either page states is that 500 px one, and neither page says how eBay's upload system treats a picture in between — both pages are linked above so you can check the wording yourself.
What is the maximum file size for an eBay picture?
12 MB per picture, according to the adding-pictures help page. eBay publishes only "12MB each" and does not state decimal or binary, so this page caps at the stricter decimal reading (12,000,000 bytes) — our reading of eBay's wording, not a figure eBay publishes. JPEG or WebP quality is lowered only when a file would otherwise exceed the cap, and no further than 45 (this tool’s own encoder floor, not an eBay figure); every output is checked against it, and any file still over it, including a PNG, which is written as a 256-colour indexed (palette) PNG and carries no quality slider to lower further, is flagged in its result row rather than shipped silently. This page accepts input files of up to 5 MB each, which is this site's own limit, not an eBay figure.
Which file formats does eBay accept?
The help page lists JPEG, PNG, GIF, TIFF, BMP, WEBP, HEIC or AVIF. This tool outputs JPEG, PNG or WebP. It opens JPEG, PNG, WebP and AVIF files only: GIF, TIFF, BMP and HEIC are accepted by eBay but are reported here as an unsupported file type — an iPhone .heic included. Export a JPEG or PNG from a HEIC original first. An AVIF original opens only if your browser can decode it.
Does eBay require a square (1:1) picture?
No requirement is stated. The help page says that, generally, photos in a 1:1 or 16:9 aspect ratio look best in listings, search results and other placements. The default preset keeps your original shape, including 16:9; the square preset pads to 1:1 with white because the recommended size is itself square, and is opt-in because eBay does not say whether flat padding counts as an added border.
Does eBay require a white background?
No background colour rule appears on the two official pages we checked (picture policy, adding pictures); the closest they come is the picture policy's Not allowed list (added borders, added text, artwork or marketing material, watermarks). The white used to pad the 1:1 preset is our default so the canvas has a single flat colour; it is not an eBay rule. Transparent areas are composited onto white for every output format on this page, PNG included: the image is drawn onto an opaque white canvas before it is encoded. JPEG carries no transparency in any case; for PNG this is how this page works rather than an eBay rule, so keep your original file if you need the alpha channel.
Does white padding count as an added border?
The picture policy lists Photos with added borders under Not allowed. It does not say whether flat padding added afterwards counts as a border, so this site cannot say how eBay classifies padding; if in doubt, use the fit-longest preset, which is the default and adds no padding. Padding extends one flat colour to fill a square canvas and adds no line or frame, but because the policy is silent on it the padding preset stays opt-in.
Does eBay allow watermarks?
The picture policy lists Watermarks of any type, including those used for ownership attributions, under Not allowed, alongside photos with added borders and photos with added text, artwork or marketing material. This site follows the picture policy and treats every watermark as not allowed. This tool does not detect, add or alter any of these; check your photos yourself before uploading. Our research notes a second eBay surface, eBay's Seller Center pages, which describe an ownership-watermark allowance. That surface is not an official policy page, we hold no captured wording and no verification date for it, and we publish none of its figures; we follow the picture policy. The full comparison is at /ecommerce-image-spec-conflicts#ebay-watermarks.
How many pictures can I add to an eBay listing?
The help page says you can add up to 24 pictures. Our research summary records these 24 as free, but the sentence we captured — "You can add up to 24 pictures" — does not contain that word, so we quote the ceiling and do not claim on this page that the pictures are free. This tool processes up to 20 images at a time — this tool's own per-run limit, not an eBay figure — and does not track how many pictures a listing already has.
My photo is smaller than 1,600 px. Will this tool enlarge it?
No. With the default fit-longest preset a photo below 1,600 px on its longest side keeps its pixel size. With the square preset it is centred on the 1,600 × 1,600 canvas at its own pixel size and the rest of the canvas is padded — neither preset scales a photo up, because enlarging adds no real detail. Every result row shows the output pixel size. If you need more pixels, export again from the original capture.
Can I reuse these files on Amazon, Walmart or Etsy?
Each marketplace publishes its own pixel, aspect-ratio and format rules, and some publish tighter file-size rules than eBay's 12 MB: Walmart's image guidelines list 5MB or less, and the same page says noncompliance may result in products being unpublished. Etsy publishes no hard cap but warns that images larger than 1 MB may not finish uploading, especially on a slower internet connection. The Amazon pages we checked state no file-size limit in MB — see resize-image-for-amazon for that page's own wording — so a file that is fine for eBay may miss another platform's file-size, background or shape rule. The multi-platform export tool produces one copy per platform from the same source image, and /ecommerce-image-spec-conflicts shows where the official pages disagree.
