What You Can Do With PDF Files
Rearrange and Merge
Drag pages to reorder them, rotate or delete them, and add pages from other PDFs or pictures.
Sign and Mark Up
Add a signature, text, highlights, shapes and notes that other PDF apps can read.
Redact Properly
Redaction removes the text and pictures underneath, not just a black box on top.
Your PDF Files Never Leave Your Device
Most online viewers upload your file to their server. Glance reads it right in your browser, so nothing is sent anywhere, and it keeps working offline.
Free and Open Source
No account, no adverts, no watermark. Read every line of the code on GitHub.
