How to fill and sign a PDF
Plenty of PDFs need more than a signature — an application, an intake form, or a tax document needs fields filled in and then signed. This guide covers completing a PDF form and signing it in a single pass, entirely in your browser.

Create your signature by drawing, typing, or uploading an image, and drop it on the signature line.

Download the completed form
Export the filled and signed PDF as a single standard file, ready to send.
Interactive form fields vs flat PDFs
Some PDFs are "fillable" — they have interactive fields you can click into. Others are flat scans or print-only forms with no fields at all. The good news is you can complete either kind by placing text and a signature directly where they belong on the page.
Filling a form this way also flattens everything into the final document, so the recipient sees your entries and signature exactly as placed, with no empty interactive fields left behind.
Tips for a clean, professional result
A few small things make a filled form look right:
- Match your text size to the surrounding print so entries do not look oversized.
- Align entries to the baseline of each line rather than floating above it.
- Date the form near your signature, using the format the document expects.
- Review every page before downloading — forms often hide a field at the bottom.
Your form data stays private
Forms frequently contain sensitive details — addresses, ID numbers, financial information. Because the document is processed in your browser and never uploaded, those details stay on your device. Send the completed form only to the party that requested it.
