From photo to PDF in three steps

Your phone is the camera, your computer is the workbench.

  1. 1

    Pair your phone

    Open web.snapdf.net on your PC or laptop and scan the QR code with your phone's camera.

  2. 2

    Shoot and edit

    Every photo appears on your computer screen right away. Straighten the corners, pick a filter and crop on the big screen.

  3. 3

    Export to PDF

    Drag the pages into order, choose the quality (up to 300 DPI) and download your PDF with one click.

Everything you need to scan fast

The speed of a phone camera with the comfort of a large screen.

Perspective cropping
Straighten photos taken at an angle by moving four corner points until the document is perfectly square.
Smart document filters
Black-and-white presets, brightness, contrast, saturation and colour temperature for text that reads clearly.
Many formats
A4 documents, A5 booklets, ID cards, driving licences and narrow receipts without distortion.
Drag to reorder
Put scanned pages in the right order before you create the file.
High-resolution export
Choose your own quality: from 72 DPI (fast and compact) to 300 DPI for professional prints.
Encrypted, device to device
Photos travel end-to-end encrypted over a WebRTC DataChannel to your computer. Nobody along the way can read them.

Your documents are never stored anywhere.

Many online PDF converters upload your files to an external server. SnapDF works differently.

Read how the technology works Privacy policy
  • Photos go end-to-end encrypted over a peer-to-peer connection (WebRTC) from your phone to your PC. Usually directly; if that fails, via a relay that can't read the content.
  • Cropping, filtering and creating the PDF all happen in the browser on your own device.
  • Close the tab and everything is wiped from memory.
  • The scanner at web.snapdf.net contains no ads and no third-party trackers.
