User guide

Overview

Open PDF files right in your browser to read, annotate, edit and sign them. Work on multiple files at once using tabs, and encrypted PDFs are supported too.

Opening a file
  1. Click the Open button at the top, or drag a PDF file onto the page.
  2. Use the + button next to the tabs to open several PDFs at once.
  3. Encrypted PDFs open after you enter the password.
Editing tools
  • Highlight: drag across text to highlight it with color
  • Text box: add text anywhere on the page
  • Rectangle / Circle: use shapes to call out a specific area
  • Arrow: point to content with an arrow
  • Pen: freehand drawing
  • Insert image: add a photo or logo
  • Signature: draw a signature with your mouse or touch and insert it (PRO)
Undo with Ctrl+Z and redo with Ctrl+Y. Edits are only applied to the downloaded file once you press Save.
Text recognition (OCR)

To recognize text in a scanned image PDF, use the OCR button at the top. You can then copy or search the recognized text.

Saving
  • Save button: downloads a PDF with your annotations included to your device.
  • Cloud button: on the PRO plan, save to and load from the cloud.
Limitations and notes
  • OCR and signature features are PRO-plan only. Rotating and deleting pages also require edit mode.
  • PDFs with print/copy/edit restrictions can still be opened without a password, but depending on the restriction you may only be able to add annotations — page deletion and rotation may be blocked.
  • OCR loads Tesseract.js from an external CDN. On networks that block external CDN access, only OCR will fail — every other feature still works normally.
  • Each file is limited to 50MB. PDFs with many pages or high-resolution scans may affect your browser's memory and speed.
FAQ
Are my edits saved to the original PDF?

No. Pressing Save downloads a new PDF file that includes your annotations — the original file is never changed.

Can I edit a password-protected PDF?

Yes, you can open it after entering the password. However, PDFs with editing restrictions may only allow you to add annotations.
