Adobe Stock Submission Checker
Batch preflight against Adobe Stock's published photo requirements (JPEG, sRGB, 4–100 MP, 45 MB), with near-duplicate groups and a clear list of what is not checked.
Stock Photo Quality Checker
Experimental noise and JPEG-compression signals, with honest real-photo test results.
Stock Image Similarity Checker
Find the same photo exported twice, resized, lightly cropped, mirrored or re-toned in a batch.
Which one should you start with?
If you are about to upload photos to Adobe Stock, start with the Adobe Stock Submission Checker. It checks Adobe's published technical requirements (a JPEG with an sRGB profile, 4 to 100 megapixels, 45 MB at most) and, in the same pass, runs the quality signals and the near-duplicate grouping. The other two tools run one of those parts on its own, for when that is the only question you have. The requirements are laid out, with what a file check can and cannot verify, in What are Adobe Stock's technical requirements for photos?
What each tool checks
- Adobe Stock Submission Checker. Pass or fail on the file format, the sRGB colour profile, the 4 to 100 megapixel range and the 45 MB limit, each linked to Adobe's help page with the date we last verified it. Files near a limit are marked "Could not verify", because Adobe does not say how it counts a megabyte or a megapixel.
- Stock Photo Quality Checker. Experimental signals for visible noise and heavy JPEG compression. These are our own heuristics, not Adobe's thresholds.
- Stock Image Similarity Checker. Groups photos in one batch that are the same frame exported twice, resized, recompressed, lightly cropped, mirrored or re-toned.
What they do not check
Watermarks, generative-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. Different angles or moments from the same shoot are usually not detected as similar, and crops larger than about 5% are often missed. Only the files in the batch are compared, not your existing portfolio.
Why two of them are experimental
We built automatic checks for focus, exposure and blown highlights. They worked on controlled test images but, on 96 real photographs from phones, cameras and AI tools, they missed most of the problem images (focus: 0 of 26), so they are switched off. In our real-photo test set the noise signal found about 4 in 10 visibly noisy images, with about 7% false alarms. Look at your photos at 100% zoom for focus and exposure.
Privacy and limits
Files are read and analysed by your browser on your device, and the page's security policy blocks it from sending data to other servers. None of these checks predicts Adobe's decision: Adobe's review thresholds and similar-content criteria are not public, and a clean result means no deterministic technical failures were found.
