Is Sign PDF really free?

Yes — no account, no paywall, no watermark added to the result.

Does my file get uploaded anywhere?

No. Sign PDF runs entirely in your browser using pdf-lib/pdf.js — your file is never sent to a server.

Is this a legally binding e-signature?

No — it draws your signature onto the page visually. It doesn't provide the identity verification or audit trail of a certified e-signature service, so it's meant for informal or internal documents rather than legally enforceable contracts.

Can I save my signature for reuse?

Not currently — you draw it fresh each time, and nothing is stored.

Can I draw with my finger on a phone?

Yes — the signature pad uses pointer events, which respond to mouse, touchscreen finger input, and stylus/pen input the same way.

Can I choose exactly where the signature goes?

You choose from 5 positions — bottom right, bottom left, top right, top left, or center — plus a size slider from 10% to 50% of the page width. There isn't free-drag placement.

Can I sign a page other than the first?

Yes — enter any page number before running the tool.

Can I add more than one signature to a document?

Run the tool once per page you need signed — each run places one signature and produces a new file, which you can then re-upload to sign a different page.

What if I don't like how my signature looks?

Tap Clear to reset the pad and draw again as many times as you want before placing it — nothing is finalized until you run the tool.

Is my signature stored or sent anywhere?

No — it's captured directly from the canvas and embedded into the PDF using pdf-lib, entirely in your browser. It's never uploaded or saved.

How to Sign a PDF Online for Free — TechDriven Tools Blog

Draw your signature and place it on any page — useful for forms and contracts when you do not need a full e-sign platform.

Sign PDF lets you draw a signature on a pad and place it at a preset position and size on a chosen page — visual signing, not a certified e-sign audit trail.

Sign PDF runs locally in your browser on TechDriven Tools. Inputs stay on your device — nothing is uploaded for this step.

When Sign PDF is the right tool

Countersign a PDF form

Draw on the pad, pick bottom-right, set size ~20%, choose the signature page number.

Internal approval packet

Place a visual sign-off on page 1 center when a full e-sign product is overkill.

Mobile stylus signing

Use pointer events on a phone/stylus; clear and redraw if the first stroke shakes.

Privacy on this workflow

Sign PDF is built to process locally in your browser so sensitive PDFs, images, or text do not need to be uploaded to an unknown server just to finish this job.

Mistakes that waste time with Sign PDF

Thinking it is legally certified e-sign — This draws pixels; it is not an identity-verified signature platform.
Covering critical text — Sign on blank margin areas; adjust size slider down.
Wrong page number — Confirm the page field before run — defaults may be page 1.

Getting reliable results from Sign PDF

Most failures with Sign PDF are input/setting issues rather than mysterious bugs: wrong units, wrong page lists, wrong language, or expecting one tool to do a sibling’s job. Re-read the option names, fix the input, and re-run — local tools make iteration cheap.

Sign PDF accelerates the workflow; it does not replace your judgment or professional advice where required.
