Fill & sign a PDF
in your browser.
Type into form fields, then add your signature. The full Edit PDF toolkit opens — text, signature, save. No upload.
Three steps. Your file never leaves this tab.
Drop your PDF form
Pick the form. It loads into your browser's memory, not a server.
Type into fields, then sign
We open the editor: form fields are ready to type into. Hit Sign to draw, type, or upload your signature, and place it where you need it.
Download the signed PDF
Save a filled and signed copy. Original file stays untouched. Run Flatten after if you want fields locked.
Frequently asked
Does it support real PDF form fields (AcroForm)?
Yes. If your PDF has interactive AcroForm fields, you can click and type into them directly — no copy-paste workaround. The values are saved into the PDF as form data.
How does the Sign button work?
The Sign button opens the same dialog as our standalone Sign PDF tool: draw with your trackpad, type a styled name, or upload a PNG. Drag the result anywhere on any page.
Does anything go to a server?
No. Filling fields, signing, and saving all happen in your browser tab. Verifiable in DevTools → Network: no upload happens.
Should I flatten after filling?
Up to you. If you want recipients to be able to change values (rare), leave it as-is. If you want a locked, non-editable copy (common for sending), run our Flatten tool after — same browser session, two clicks.
What if my PDF has no form fields?
You can still add text on top of the page using the editor's Text tool, then sign. The result is visually identical to filling a real form, even though the source has no AcroForm.
