Edit and annotate
Text, highlights, redaction, arrows, signatures (upload or draw), and images—placed directly on the page.
Everything You Need for Daily PDF Work
Editing, Request Sign, sharing, and organization in one browser workspace—no install required.
Request Sign
Invite signers by email, place fields, send private links (no OtterPDF account needed). Resend reminders; get a flattened PDF and read-only link when done.
View-only share links
Optional read-only URLs from the editor so others can open a file in the browser—separate from signing links.
Merge and split
Combine PDFs into one document or split by flexible page ranges.
Search and navigation
Full-text search, thumbnails, and keyboard shortcuts for long documents.
Version history
Save named versions and roll back when you need an earlier state.
Files and folders
Folders, color tags, bulk moves, rename, and restore from trash.
Storage meter
See allowance usage on the dashboard and in Files. Uploads, versions, and completed signed PDFs all count toward quota.
Activity log
Chronological workspace activity for signed-in users, with pagination.
Security and access
Private storage, password-PDF unlock, and admin or standard roles for teams.
Guest mode
Try without registering. Create an account for persistence, Request Sign, and share links; verified users can migrate eligible guest files.
Print and export
Download from your library; print the secured original or the edited PDF after unlock.
