Ratings and reviews

It works really well for me. One negative point is that saving PDF does not support saving to the Onedrive file provider. Funny thing is, that the Onedrive provider is supported when opening photo files. If I can save to Onedrive, it will be 5 stars for me.

While adding a new page, I cannot access existing added pages anymore. The app is very rudimentary and has a hard time recognizing corners of a paper on a table. How did this get such a high rating?

Does exactly what it says. Good replacement for disappeared cropping function from Google Photos. The only thing I would change is the possibility to default savings files as jpeg.

What’s new

- New: manual dewarping for curved book pages
- New: multi-page workflow – import PDF pages, batch OCR, memory-friendly export; drafts survive restarts
- New: re-crop any page from its original photo (curves included)
- Corner detection ~9× faster and better with tilted documents
- Fix: TXT file only exported when text was found
- Fix (Paddle OCR): long justified lines no longer lost; "Best quality" now works as intended
