Resize product images for Walmart Marketplace

The official table gives it as "Pixel Dimensions: 2200px x 2200px" and does not label it a minimum. Because the page prints the figure without saying whether it is a minimum, a maximum or a suggestion, the spec table below marks it as stated rather than required, and we read it as a target rather than a hard floor. The only pixel figure in that table labelled a minimum is the 1500 × 1500 minimum for zoom, and the page scopes that label to the zoom feature. This page outputs a 2200 × 2200 canvas, so every file you download is that size.

Walmart's table says only "Bit Depth: 8 bits per pixel" and does not define the term, and two rows of the same table have to be read together: taken literally, eight bits in total for each pixel describes an indexed or greyscale file, which cannot at the same time be the RGB the colour-format row requires. Walmart lists both rows as requirements on the same page and does not flag any tension between them, so this is our reading rather than a disagreement between two separate official pages — the tension sits between two rows of one official table: we read the depth as 8 bits per channel in RGB, the depth an ordinary JPEG export writes, because that is the only reading under which both rows can be satisfied at once. 8 bits per channel is our reading; 8 bits per pixel is Walmart's wording, and we quote both rows as they stand in the spec table below. On that reading, 16-bit PNG and palette (indexed) PNG do not comply, even though they look identical on screen. This page writes a standard 8-bit-per-channel RGB JPEG. It does not offer PNG output, because the PNG encoder on this site writes an indexed (palette) PNG — one of the two cases that reading rules out. To inspect a file without changing it, use the bit depth and colour mode checker.

If it is larger than the canvas it is scaled down proportionally until it fits; if it is smaller it is left at its own pixel size and not scaled up at all. Either way it is centred on a 2200 × 2200 canvas and the empty area is padded with exact white, RGB 255/255/255, which is the value in the Background row of the official table, and nothing is cropped. Walmart's content rules also ask sellers to crop close to the frame and avoid excessive empty background, while telling them not to enlarge small images to fill space, so a heavily padded 2200 × 2200 output can still read as too much white space — re-shoot or export a larger, tighter original where you can.

No. The official table has no resolution row; it gives pixel dimensions and bit depth but no ppi or dpi value. This page leaves density metadata unwritten. The ppi figure you may have seen elsewhere is listed in the section on numbers that are not on the official page.

The official page accepts JPEG, JPG, PNG and BMP and states that GIF images are not permitted. This page reads PNG, JPEG, WebP and AVIF. HEIC and BMP files are not read — convert them first, which matters because BMP is on Walmart's own list and iPhone photos are often HEIC. Output is JPEG only — PNG output is not offered here, because the PNG encoder on this site writes an indexed (palette) PNG, which by our reading of the Bit Depth row would not comply. WebP and AVIF inputs are re-encoded to JPEG, because neither is on Walmart's accepted list.

Transparent areas are composited onto exact white, RGB 255/255/255 — the value in the Background row of the official table — because the canvas is filled with that white before your photo is drawn onto it. Opaque pixels are unchanged apart from ordinary re-encoding.

Yes. Re-encoding strips EXIF data and embedded colour profiles, and that also removes any XMP dc:subject keywords — including the contains-synthetic-performer keyword Amazon asks sellers to add to images that include AI-made people. Stripping is our own choice rather than a Walmart instruction, because Walmart's page specifies no metadata handling. If that keyword applies to your images, re-apply it after export: our disclosure-tag page carries Amazon's official wording, the exact field it goes in and the cases where the keyword is not needed, and the Amazon source is listed under Sources.

Output is JPEG only, and the page lowers quality in steps until the file is within Walmart's published "File Size: 5MB or less" line. Walmart does not define MB and publishes no byte figure, so the cap we compress to is our own reading of that line — we use the stricter decimal 5,000,000 bytes rather than 5 MiB, so a pass here is a pass under either reading. If a file still exceeds it, the result row is flagged. Nothing over the limit is presented as being under it.

The output canvas is always 2200 × 2200 px, but a photo smaller than it is centred at its own pixel size and the rest is padded with exact white — it is never scaled up, because Walmart's content rules tell sellers not to enlarge small images to fill space. The result row says it was kept at its own pixel size. Walmart's 1500 × 1500 figure is scoped by the page to the zoom feature, so this page neither refuses nor changes a file because of it — check your source's pixel size yourself if zoom matters to you. Walmart also asks for tight framing with little empty background, so padding is not a substitute for a larger original: export a larger file from the original capture if you still have it.

No. This page works from the numeric table on the official page and does not look at what is in the picture. Walmart's page carries separate content rules alongside that table; read them on the linked page before you upload.

The official page says: Noncompliance may result in products being unpublished. That is the full extent of what the page states; it gives no pixel threshold or timeline for it, which is why this sentence sits here rather than in the spec table — it is a consequence, not a spec value with a hardness.

Yes. Walmart's table states "Aspect Ratio: 1:1 (Square)", while Amazon's clothing guidelines state "Minimum aspect ratio is close to 3:4 (width/height) and 85% of the total image area occupied" (our research records the Amazon material it relies on here under Amazon’s US site, so we make no claim about Amazon’s other marketplaces). Amazon's own wording calls that ratio a minimum, so a 1:1 square main image does not meet it, and Amazon states that non-compliant images may result in the listing being suppressed (hidden) from search until a compliant image is provided, or in the image being removed or modified — its wording is "we may", not a statement of what will happen. This page produces Walmart's square canvas. No page here re-shapes a photo to Amazon's clothing ratio — that has to come from the shot or the export; our Amazon resizer keeps your photo's own shape and shows the clothing line in its spec table for you to check. The 85% figure is not clothing-specific — our research records it as applying to all product images, not only main images: Amazon’s Product Too Small page states "The product must occupy at least 85% of the image area" — measured as image area, not longest side. Both Amazon pages are linked under Sources with the date we checked them. The spec-conflicts page lists differences like this side by side with the official wording, and the multi-platform export produces one set per platform from the same source photos.

We check against the Walmart Marketplace Learn image guidelines page linked under Sources (last updated 2026-05-11, verified 2026-09-19). Our research did not record a market scope for that page, so this page says only "Walmart Marketplace" and makes no claim about any particular country's site. The link and the date we checked it are under Sources.
