Document Scanner: Scan to PDF

Point your phone at a page. The frame finds the edges, squares the page, and saves a clean PDF. That is the whole app.

Built to be fast
Edge detection runs live in the viewfinder, so the frame is already locked before you press the shutter. Auto-capture fires when you hold steady, and you can turn it off. The shutter is always there.

Built to be honest
No account. No sign-in. No watermark on your pages. No subscription gate in front of a feature you already used. Scanning, filters and export all happen on this phone, and your documents never leave it: nothing in the app uploads a page. The app is free and shows a few quiet ads, in the document list and after an export, never while you scan or edit.

What it does
• Live edge detection with a stable frame, and perspective correction to a true rectangle
• Auto-capture, or the shutter, or import from your gallery
• Continuous multi-page scanning with no prompt between pages
• Drag to reorder, retake a single page, insert a page in the middle
• Filters: Black & White, Enhance, Greyscale, Ink Saver, Original
• Shadow removal, brightness and contrast, straighten by text direction
• Export PDF at A4 or Letter, or JPG and PNG
• Share, print, or save wherever you like
• Search your scans, rename them, delete them

For real conditions
Scanning happens in offices at night, on wooden desks, on patterned tablecloths, over glossy receipts. The detector was tested against twenty of those situations. When it cannot find a page it tells you instead of guessing, and the corners are always yours to drag.

Dark mode from the start
The viewfinder is the product, so the interface gets out of its way. Dark mode was designed first, not added later.
