Turn any photo into a clean, scanned PDF.
Straighten crooked shots, lift the shadows, and stack pages into one shareable PDF — without ever sending your documents to a server.
Filter
Corners
Drag the four red handles onto the edges of your document, then save the page.
Everything a pocket scanner does, minus the app.
Perspective straighten
Drag four corners onto your page and Scanline rebuilds it as a flat, front-on rectangle — even from an angled photo.
Page filters
Punch up faint text with Magic Color, drop to Grayscale for a lighter file, or go pure Black & White for maximum contrast.
On-device processing
Every crop, filter and export runs in your browser's own memory. Nothing is uploaded, so nothing can leak.
Multi-page stacking
Scan a whole notebook or contract page by page, then bind everything into a single, ordered PDF.
From photo to PDF in under a minute.
Add a photo
Snap your document or pick an existing image. Add more shots any time to build a multi-page file.
Straighten and filter
Line up the corner handles with the edges of the page, choose a filter, then save it to your stack.
Export your PDF
Reorder or remove pages if needed, then download one clean PDF — or grab a single page as a JPG.
cleaner scan
- Even light beats bright light. Diffuse lighting avoids the dark shadow one corner tends to get.
- Use a contrasting surface. A white page on a dark desk gives the corner-detection something to grab onto.
- Keep the camera parallel. Shooting straight down, rather than at an angle, keeps text sharp after straightening.
Your files never leave this tab.
Most "free" online scanners quietly upload your photo to a server, process it there, and send it back — which means a copy of your ID, contract or notes now lives somewhere you don't control.
Scanline does the opposite. The corner detection, the perspective warp, and the PDF assembly all happen with JavaScript running locally in your browser. There is no upload step, because there is nowhere for your file to go.
Whoever has a stack of paper and no scanner.
Notes & homework
Digitize handwritten notes and whiteboard photos into PDFs your LMS will actually accept.
Receipts & contracts
Turn a photo of a receipt into an expense-ready file, or scan a contract before you sign.
Forms & IDs
Archive ID cards and official paperwork at a resolution clean enough for OCR later on.
Family archives
Preserve old photos, recipe cards and letters before time and light fade the originals.
Browser scanner vs. the alternatives.
| Option | Where it wins | Where it costs you |
|---|---|---|
| Scanline (this page) | Nothing to install, works on any device with a browser, files stay local. | You need an internet connection to load the page the first time. |
| Phone scanning apps | Convenient for scanning on the move. | Usually needs a download, and many gate PDF export behind a subscription or a watermark. |
| Desktop scanning software | Strong for large batch jobs tied to a physical scanner. | Paid licenses, heavier installs, and a learning curve for occasional use. |
