How to clean a document photo
To clean a document photo, add your JPG to the scan cleaner, let auto deskew straighten the page, fine-tune the rotation if needed, apply paper whitening and contrast to lift the text, and export a cleaner JPG. The processing runs in your browser, so your document never leaves your device.
Phone photos of paper often come out tilted, with gray or yellow backgrounds and uneven lighting. Deskewing squares up the page, while whitening and contrast push the background toward white and make the text crisp, giving you a result that reads like a real scan rather than a snapshot.
Why it stays photo-to-JPG instead of PDF-first
Many people first need the document photo itself to look cleaner before moving on to OCR or PDF assembly, so cleaning the JPG is its own useful step rather than being bundled into a PDF builder.
By exporting another JPG, the cleaner fits naturally before any later step: you can clean the image here, then feed it into an image to PDF tool or a text recognizer. Keeping the scope tight makes the cleanup predictable and easy to redo.
Is the scan cleaner free and private?
Yes. The JPG scan cleaner is free with no sign-up, no watermark, and no usage limits.
It is private because deskew, cleanup, and export all happen locally in your browser. Your scan photo is never uploaded to a server, which matters for receipts, IDs, and personal paperwork.
