Sign documents without printing

Printing a PDF just to sign it — then scanning it back in — is a ritual that belongs in the past. When you sign a PDF with GroPDF, the whole thing happens on screen: draw your signature with your mouse or finger, or type your name and let it render in a natural script style. Then tap the document preview to drop the signature exactly where it belongs — on the signature line, next to the date, wherever you need it. Drag it to nudge it into place.

How to sign a PDF

  1. Drop your PDF onto the page. It never leaves your device.
  2. Create your signature — draw it on the pad, or switch to the Type tab and enter your name.
  3. Tap the preview to place the signature, then drag it to fine-tune the position. Use the arrows to sign additional pages, and the size slider to match the signature line.
  4. Apply & download. Your signature is burned permanently into the PDF.

Because everything runs locally in your browser, your signed documents stay private — nothing is uploaded to a server, which matters when you're signing contracts, offers, or ID paperwork. The signature becomes a permanent part of the PDF pages, so it looks right in any PDF reader and prints cleanly.

Frequently asked questions

Is it free to sign a PDF with GroPDF?
Yes — completely free, with no limits on how many documents you sign and no watermark added.
Is my signature secure? Where is it stored?
Your signature never leaves your device. It's drawn in your browser and embedded directly into your PDF — we never see or store it.
Can I sign multiple pages?
Yes. Use the page arrows to move between pages and tap each page to place your signature there.
Is this a legally valid electronic signature?
GroPDF places a visual signature image into the PDF, which is accepted for most everyday agreements. For contracts requiring certified or qualified electronic signatures under eIDAS or similar laws, use a certified e-signature provider.
