Product photo QA checklist
Last reviewed 2026-09-17. Every competitor figure links to the vendor's own page.
Most product image problems are caught in under a minute if you check in the right order: dimensions first, because a rejected upload blocks everything else, then cutout edges at full zoom, then colour accuracy, then consistency across the set.
The checklist
| Check | How | Fails if |
|---|---|---|
| Pixel dimensions | Compare against the platform minimum | Below the zoom threshold or the stated minimum |
| Cutout edge | View over mid-grey at 100% zoom | Fringing, halo, jagged edge or missing detail |
| Transparency intact | Place on a coloured background | Background shows as white or black, meaning alpha was lost |
| Colour accuracy | Compare against the physical product | Visible hue or saturation shift |
| Colour profile | Confirm sRGB and embedded | Untagged, or tagged as a wide-gamut space |
| Subject scale | Compare against others in the set | Product fills a noticeably different share of frame |
| Crop and alignment | Check centring and margins | Inconsistent with the rest of the catalogue |
| Compression | Inspect edges and flat areas | Blocking, banding or visible ringing |
| File format | Confirm the platform accepts it | PNG where JPEG required, or the reverse |
| File naming | Follow your own convention | Unidentifiable at a glance in bulk |
Why grey, not white
Reviewing cutouts against a white page hides the two most common edge defects. A light halo is invisible on white. Dark fringing from premultiplied alpha is barely visible. Both show clearly against mid-grey.
Set your review background to roughly 50 percent grey and every edge problem becomes obvious at a glance. It is the single highest-value change to a review process.
Consistency is worth more than perfection
Customers rarely evaluate one product image in isolation. They scan a grid, and the eye detects variation in scale, crop and background far faster than it judges absolute quality. A catalogue of consistently good images outperforms a mix of excellent and average ones.
Fix this by defining the rules once: the share of frame the product fills, the margin around it, the background, the aspect ratio. Then check every image against those rules rather than against your own taste on the day.
Spot-check at scale
- Contact-sheet the whole set and scan for anything visibly out of line
- Full-check ten percent at random, plus every image of a difficult product
- Always full-check white, black, transparent and reflective items; they fail most often
- Verify one image end to end on the live listing before uploading the rest
Frequently asked questions
What should I check before uploading product photos?
Check in order of cost to fix. Pixel dimensions against the marketplace minimum, then the cutout edge at 100 percent zoom, then colour against the physical product, then consistency across the whole set. Dimension failures block the upload entirely, so they come first.
How do I check a cutout edge properly?
Place the cutout over a mid-grey background and view at 100 percent. Grey reveals both dark fringing and light halos, which both disappear against white. Inspect the boundary systematically rather than glancing at the whole image.
Why do my product colours look wrong online?
Usually a colour space mismatch. If the file is Adobe RGB and the platform assumes sRGB, every colour shifts toward neutral. Convert to sRGB and embed the profile before uploading.
How important is consistency across a catalogue?
More than the quality of any single image. Shoppers compare items side by side in a grid, so variation in scale, crop or background reads as unprofessional even when each photo is individually good.
What is the most commonly missed defect?
Fringing along the cutout edge, because it is invisible against the white page where most people review. It only appears once the image sits on a coloured background, which is often the first time a customer sees it.
