What it checks
- Hard technical requirements (Pass / Fail): the file really is a JPEG, uses the sRGB colour profile, is between 4 and 100 megapixels and at most 45 MB — as listed on Adobe's photo submission requirements page. Each result links to the source and shows when we last verified it.
- Quality signals (experimental): visible noise and heavy JPEG compression, measured with public image-quality methods. These are our heuristics, not Adobe's thresholds. Automatic focus, exposure and highlight checks were switched off after they failed our real-photo tests — check those yourself at 100% zoom.
- Near-duplicates: the same photo resized, recompressed, lightly cropped, mirrored or re-toned inside your batch.
- Coverage / Not checked: watermarks, AI anomalies, logos and trademarks, model and property releases, commercial value and the moderator's judgement are listed as not checked — so you know what is still on you.
What it does not do
It does not predict whether Adobe will accept your photos, give an approval score, or fix files for you. Adobe's review thresholds and similar-content criteria are not public; a clean result means no deterministic technical failures were found, not that a submission will pass.
FAQ
- Why does an untagged JPEG show "Could not verify" for sRGB?
- Adobe asks for a JPEG with the sRGB colour profile. Without an embedded profile the colour space cannot be confirmed from the file, so we say so instead of guessing. Export with "Embed colour profile: sRGB" to remove the doubt.
- Why "Could not verify" just above 4 MP or just over 45 MB?
- Adobe does not say whether a megabyte or megapixel is counted in powers of 1,000 or 1,024. Files inside that gap are flagged for you to check instead of being passed or failed silently.
- Are my photos uploaded?
- No. Files are read and analysed by your browser. The page's security policy blocks it from sending data to other servers.
