CI for product photos

Drop a folder.
Get photos every marketplace accepts.

Photolint checks your product photos against the real rules of Amazon, Etsy and Shopify, then fixes what software can fix: pure white backgrounds, sharp AI upscaling, correct framing, and tells you honestly when it can’t.

One pass, four moves

01 Drop A folder, a selection or one photo. HEIC straight from the camera works.
02 Lint Every photo measured against each platform’s real rules, before anything is changed.
03 Fix White background, AI upscale, framing, file-size caps, EXIF cleanup. Only what software can honestly fix.
04 Ship One zip: a folder per platform, correct names, plus ready-made import files.

The lint report

Know before a single pixel is touched

Every photo is measured on your device: resolution, file size, background whiteness, product fill, batch consistency. Every red row says whether the pipeline can fix it, or whether no software can. Nothing is guessed; what can’t be measured says could not verify.

The pipeline does the boring parts

Six jobs you never do by hand again.
01 amazon · main-white-bg
Pure white backgrounds AI subject masking with precise edges, then the output is re-linted with the same rules. If the mask isn’t confident, it says so; never a silent botch.
02 amazon · min-resolution
4× AI upscale Tile-based Real-ESRGAN brings 1000px phone shots up to zoom-ready 1600px+, entirely in the browser.
03 amazon · min-fill
Framing & fill Products recropped to each platform’s fill minimums, padded to square on pure white where required.
04 shopify · etsy · amazon
Import files included The zip carries shopify/images-import.csv, Amazon image columns and alt-text.csv; upload and go.
05 never guessed
Honest verdicts Four verdicts only: pass, pipeline will fix, could not verify, reshoot. Nothing is ever guessed.
06 sku-view slugs
EXIF stripped, names fixed Metadata cleaned, files renamed to SKU-view slugs each platform expects.

Privacy by architecture

Your photos never leave your device. Not a policy: a physical fact. There is no upload endpoint to send them to. The whole pipeline, AI models included, runs inside this browser tab.
