One browser workspace

Page edits, markup, search, redaction, and export in one place—nothing to install.

Request Sign

Email signers, place fields, send private links (no OtterPDF account needed). Get a flattened PDF and read-only link when everyone’s done.

View-only links

Optional read-only URLs from your library—separate from Request Sign signer links.

Secure unlock

Password-protected PDFs stay locked until you enter the password—safer for sensitive files.

Storage at a glance

Dashboard and Files show usage. Uploads, versions, and completed signed PDFs count toward your quota.

Folders & activity

Color-tagged folders, bulk moves, trash and restore, plus an activity log for recent actions.

Signatures in the editor

Upload or draw a signature and place it on the page without leaving the document.

Merge, split, reorder

Combine PDFs, split by page ranges, and reorder pages from the editor workflow.

Print & export

Download from your library; print the secured original or your edited PDF after unlock.

How It Works

1) Upload

Add one or multiple PDFs and open them instantly in your browser.

2) Edit & collaborate

Annotate, redact, sign, reorder, search—or start Request Sign and share links when you’re ready.

3) Export & deliver

Save versions, download PDFs, and share read-only copies when signing completes.
