What is PDF e-signing?

It's doing what you'd do with a stamp or pen on paper — directly on a PDF. No print → sign → rescan cycle; you place a signature image onto the PDF and you're done. Especially handy for "just add a signature" documents like agreements, consent forms, simple contracts, and application forms.

This tool inserts the signature as an image into the PDF. The original text, tables, and images stay intact; only your signature is placed where you want it. Everything runs in your browser — files never leave your device, so you can safely sign contracts and ID-related documents.

How to use — 4 steps

  1. Select PDF — load the file and a preview appears. Use ← → for multi-page PDFs.
  2. Create signaturedraw with mouse/finger, type your name, or upload a signature image.
  3. Position & resizedrag the signature to the right spot and pull the bottom-right handle to size it. Opacity adjustable.
  4. Download — get the signed PDF. Original untouched, signature added.

Common use cases

3 signature methods — which one?

MethodHowBest for
DrawMouse / touch handwritingMost natural sign on tablet/phone
TypeName + cursive/serif/sansFast and clean, when drawing is awkward
ImageUpload signature/stamp PNG·JPGReusing an existing signature or company stamp

💡 Tip — for a handwritten signature, write on white paper with a black pen, photograph it, and upload via the Image method for the cleanest result. A transparent PNG blends in best.

E-signature vs certified digital signature

This tool produces a "visual e-signature" — it places a signature image to indicate "this person agreed". That's sufficient for everyday agreements, internal approvals, and simple consents.

A certified digital signature, by contrast, uses a PKI certificate and timestamp to cryptographically prove "no tampering" and "when it was signed". For real-estate contracts or documents with legal-dispute potential, use a certified e-signature service.

FAQ

Are my PDFs uploaded to a server?
No. Everything runs in your browser via pdf-lib·pdf.js (WebAssembly); the operator cannot see your PDF.
Is this legally binding?
This tool visually inserts a signature image. No certified digital signature (PKI) or timestamp. For legally critical contracts use a certified e-signature service. Fine for ordinary agreements, internal approvals, simple consents.
Can I create the signature in multiple ways?
Yes — (1) draw by hand (2) type your name (cursive/serif/sans) (3) upload a signature image.
Can I adjust position and size?
Yes. Drag the signature on the preview to position it, and drag the bottom-right handle to resize. Opacity too.
Can I sign a specific page in a multi-page PDF?
Yes. Move to the page (← →), place the signature, and download — the signature is inserted on that page.
