Scan to PDF Online

Scan any paper document to PDF using your phone camera, webcam or existing photos. Every page is processed locally — nothing is sent to a server.

Turn phone photos into scanner-quality PDFs

The fastest way to scan a document to PDF without an app: open this page on your phone, tap Use camera, hold it over the paper, and press Capture. The image is enhanced with a document-scanner filter and turned into a PDF page immediately. Add more pages by capturing again or uploading photos from your gallery.

The output is a real PDF — proper page dimensions, one image per page, letter or A4-friendly aspect ratio, and text that stays sharp when printed. Because every page is embedded as a compressed JPEG, file sizes stay small even for long documents.

Which filter should I use?

  • Contracts, forms, letters: Auto-enhance keeps coloured letterheads and stamps while cleaning up the background.
  • Handwritten notes, textbook pages, receipts: Black & White gives the cleanest look and the smallest file size.
  • ID cards, photos, coloured artwork: Original or Auto-enhance — you want the colours preserved.
  • Whiteboards and blackboards: Grayscale often works best when lighting is uneven.

Scanning tips for the best quality

  • Put the document on a plain, dark surface for the highest contrast against the edges.
  • Keep the phone flat and directly above the paper — a slight tilt distorts the shape.
  • Use natural light or a bright overhead light. Avoid a single hard shadow across the page.
  • Fill the frame with the document, but leave a small margin so nothing is cropped.
  • For multi-page scans, keep the phone at the same distance for each page so pages come out the same size.

Works on every device

The scanner runs in any modern browser: Chrome, Safari, Firefox, Edge, Brave, Samsung Internet and Opera. On desktop it uses the webcam or drag-and-drop; on mobile it uses the rear camera at up to Full HD. Because all processing happens on your machine, quality is limited only by your device — not by an upload quota or a server.
