1) Set up request
Choose your PDF, add signer names/emails, and define the request title.
Collect PDF Signatures Without the Usual Back-and-Forth
Send one document to one or many signers, track progress, and receive a finished copy when everyone is done.
What Is Request Sign?
Request Sign is OtterPDF's multi-party signing workflow for PDFs in your account. You upload or pick a file, place signer fields, and email private links. Signers open in the browser and complete only their assigned fields. No app install and no signer account required.
How It Works
2) Place fields
Drop Name, Initial, DOB, date/time, and signature fields on the PDF and assign each field to a signer.
3) Send private links
Each signer gets their own private URL by email. They sign in-browser with no OtterPDF account required.
4) Track and resend
Monitor status from the prepare page and resend reminders to anyone still pending.
5) Complete and protect
After all signers finish, OtterPDF generates a flattened signed PDF and applies edit-protection before delivery.
6) Share final copy
Owner and signers receive a read-only link to view, print, or download the completed document.
Faster turnaround
Collect signatures in one coordinated flow instead of chasing email attachments and scans.
Clear signer experience
Signers only see what they need to fill, reducing confusion and mistakes.
Works for external parties
Customers, vendors, and partners can sign from the link without creating an account.
Status visibility
See who has signed, who is pending, and resend to non-completed recipients.
How Completed PDFs Are Protected
When a request reaches 100% completion, the signed PDF is generated first, then passed through a protection step that locks edit permissions. This helps prevent post-signing changes or tampering to the completed copy.
- Signatures and field values are flattened into the final PDF.
- A background protection worker applies qpdf edit-protection to the completed file.
- Until protection finishes, the signed link shows a pending status page.
- Once protected, the file is available via read-only link for view/print/download.
Legal note: electronic signature requirements vary by jurisdiction (for example eIDAS, ESIGN/UETA). Request Sign provides technical workflow tools; confirm legal and compliance requirements for your use case.
