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.

Steps at a glance

  1. Upload your PDF.
  2. Draw your signature on the pad (or type it and pick a handwriting-style font).
  3. Drag the signature to the right spot on the page; resize if needed.
  4. Place it on additional pages if required, then download the signed PDF.

Why sign PDFs with GroPDF?

Print-sign-scan is a ridiculous ritual in 2026, yet people still do it because 'real' e-signature platforms charge per envelope. For everyday documents — HR forms, school permissions, freelance contracts — a drawn signature placed on the page is what everyone actually needs. GroPDF gives you that without accounts, envelopes, or per-document fees, and the signature becomes part of the page so it shows correctly everywhere.

Common use cases

  • Signing a job offer letter or HR form from your phone.
  • Adding your signature to a freelance contract before returning it.
  • Signing school permission slips without a printer.
  • Initialing each page of a multi-page agreement.

Things to know

This creates a visual signature on the page — convenient and widely accepted for everyday documents, but it's not a cryptographic digital signature (the kind with certificates). For high-stakes legal or government filings that require certified signatures, use a qualified e-signature service.

Frequently asked questions

Is this a legally valid signature?

For most everyday documents, a drawn signature placed on the document is accepted the same as a scanned wet signature. Requirements vary by jurisdiction and document type — for regulated filings, check whether a certified digital signature is required.

Can I reuse my signature?

Draw it once per session. For privacy, GroPDF doesn't store your signature anywhere — it exists only in your browser while you work.

Does it work with a finger on mobile?

Yes — the signature pad supports touch. Use a stylus or your finger; zoom the page for precise placement.

Can I add the date alongside?

Use the Edit PDF tool's text feature after signing, or type the date as part of your typed signature.

What's the difference between drawn and typed signatures?

Drawn uses your actual handwriting via mouse/touch; typed renders your name in a script font. Both are placed as page content.
