Processed entirely on your device
Your file never leaves your device.
Thryve Sign fills and signs PDFs right where they open: type into text and date fields, tick checkboxes, and draw a signature or initials wherever they belong. The whole document is rendered and edited on your device, so it never has to touch a server on its way to being signed.
How Thryve Sign works
- 1
Drop a PDF
Works with any standard PDF up to 500 MB. It renders page by page on your device and stays in your browser tab from start to finish.
- 2
Place your fields
Add text, date, checkbox, signature, and initials fields anywhere on any page. Drag to move, pull a corner to resize, and delete anything you added by mistake.
- 3
Fill it out
Click a text or date field to type, click a checkbox to tick it, or click a signature or initials field to draw it with a mouse, trackpad, or touchscreen.
- 4
Export the signed document
Every field is baked directly onto the original pages, keeping the source document’s quality and selectable text intact, then it downloads straight to your device.
Why teams choose Thryve Sign
Your document stays with you
Rendering, field placement, and export all run locally using pdf.js and pdf-lib. No request ever carries the file off your device.
Five field types, fully positionable
Text, date, checkbox, signature, and initials, each placed and resized independently on any page.
A signature that looks like yours
A built-in pad captures a natural, hand-drawn signature or initials with mouse, trackpad, or touch, so there is no uploaded image to fake or misplace.
A free tier, then unlimited
10 exports a month at no cost. A one-time Thryve Sign Pro purchase removes the ceiling for good.

Frequently asked questions
Does Thryve Sign upload my PDF?
No. Your document is rendered, filled, and exported entirely in your browser using pdf.js and pdf-lib. It never reaches a server.
Is this a legally binding e-signature?
Thryve Sign draws your signature, initials, and filled fields onto the PDF the same way you would fill and sign a printed page by hand. It does not provide audit trails, identity verification, or certificate-based signatures, so check whether your situation requires those first.
What field types can I add?
Text, date, checkbox, signature, and initials. Each one can be placed anywhere on any page, then dragged, resized, or deleted.
Does the exported PDF keep its original text and quality?
Yes. Unlike tools that flatten every page into an image, Sign draws your filled fields directly onto the original PDF, so the existing text stays selectable and nothing loses quality.
Is Thryve Sign free to use?
You get 10 exports a month at no cost. A one-time purchase removes the limit entirely.
