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
- Select PDF — load the file and a preview appears. Use ← → for multi-page PDFs.
- Create signature — draw with mouse/finger, type your name, or upload a signature image.
- Position & resize — drag the signature to the right spot and pull the bottom-right handle to size it. Opacity adjustable.
- Download — get the signed PDF. Original untouched, signature added.
Common use cases
- Agreements & consent forms — sign and return without printing/scanning
- Internal approvals & simple contracts — draw your signature, email instantly
- Applications & forms — drop a typed name signature quickly
- Lease / transaction confirmations — make a stamp PNG once, reuse it
- School / academy paperwork — guardian signature by finger on phone/tablet
- Freelance quotes & invoices — add a signature for credibility
3 signature methods — which one?
| Method | How | Best for |
|---|---|---|
| Draw | Mouse / touch handwriting | Most natural sign on tablet/phone |
| Type | Name + cursive/serif/sans | Fast and clean, when drawing is awkward |
| Image | Upload signature/stamp PNG·JPG | Reusing 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.
| Aspect | Visual e-signature (this tool) | Certified digital signature |
|---|---|---|
| Method | Signature image inserted into PDF | PKI certificate + encryption + timestamp |
| Tamper proof | No | Yes |
| Cost | Free | Paid (cert service) |
| Fits | Agreements, consents, approvals | Real estate, critical contracts |
