The device chooses whether to open its camera or photo picker. HEIC and animated images are not supported.
How to use it
- Add PNG, JPEG or WebP document photos, use the slanted example, or open the camera picker on a supported phone.
- Check the proposed four corners and correct them by dragging, keyboard arrows or numeric coordinates. Choose known page proportions when the estimate looks stretched.
- Adjust color, grayscale or black-and-white mode, contrast, shadow reduction and rotation. Compare each corrected preview with its original and confirm it.
- Arrange or remove pages, choose the PDF paper size and export the confirmed image pages as a PDF.
The example contains a tilted, shadowed document. Choosing its four real corners and A4 proportions produces a straight page; 90° rotation changes the corrected orientation before export.

Can it recover missing text or make a searchable scan?
No. Corrections change existing pixels; they do not generate letters or perform OCR. The PDF contains images without searchable text. Automatic corners and proportions are suggestions. Black-and-white conversion can remove faint marks; compare with the original. Up to 10 pages, 10 MiB/20 MP per image and 40 MiB combined; corrected pages are at most 4 MP/2,560 px per side. The phone decides whether the camera picker opens a camera or existing photos.
