Get a tidy scan without a scanner. Upload a phone photo of a document and the tool finds the four corners of the page automatically — drag them to adjust if needed — then corrects the perspective so an angled shot becomes a straight rectangle. Enhance mode estimates the lighting and removes shadows so the paper turns evenly white and text becomes crisper; black & white and greyscale looks are also available. Download as JPG or as an A4 PDF. Great for contracts, invoices, receipts, homework, book pages and whiteboards — all processed in your browser.

## How to use

1. Upload one or more phone photos of a document
2. Check or drag the four corners onto the page edges and choose a scan effect and output ratio
3. Download the current page, or export all pages as one PDF

## Features

- Automatic page detection with manual fine-tuning
- Perspective correction for angled shots
- Shadow removal, white-paper enhance, B&W scan
- JPG / PDF export, never uploaded

## FAQ

### How should I take the photo?

Place the page on a darker surface that contrasts with the paper, use even lighting and keep the whole page in frame.

### The edges were not detected — what now?

Just drag the four blue dots onto the corners of the page; the corrected result updates live on the right.

### Can I combine several pages into one PDF?

Yes. Drop in several photos, adjust the corners on each page, then click Export all to get a single multi-page PDF.

### Are my files or data uploaded?

No. Everything runs locally in your browser with no network upload, and is discarded when you close the page.
