Almost every “free” e-signature site asks you to upload the contract, create an account, and often watermarks the result or caps how many documents you can sign. For an offer letter, an NDA, a lease or a tax form, uploading a document full of personal details just to add your name is more exposure than the job needs. You can sign a PDF online for free without any of that — the signing happens entirely inside your own browser.
Why sign a PDF in the browser
- Privacy — contracts, IDs and financial forms never leave your device, so there is no uploaded copy to leak or retain.
- No account, no watermark — nothing to sign up for and no branding stamped across your document.
- No limits — sign as many PDFs as you like; there is no cloud bill to meter.
- Speed — no upload or download round-trip, so even a large scanned agreement is ready to sign instantly.
Step-by-step
- Open the free PDF signer.
- Drop in the PDF you need to sign.
- Create your signature — draw it, type it, or upload an image.
- Drag the signature onto the right page, then resize it to fit the signature line.
- Add the date or your initials the same way if the form needs them.
- Click Download — the signed PDF saves straight to your device.
Because everything runs locally, the document you just signed was never sent anywhere, ours or anyone else's.
Three ways to add your signature
- Draw it — sign with a mouse, trackpad or finger on a touchscreen. Best for a genuine handwritten look.
- Type it — type your name and pick a handwriting-style font. Quick and legible for routine forms.
- Upload it — photograph your real signature on white paper and upload it; a transparent PNG drops in cleanly over the line.
Is an electronic signature legally valid?
In most countries a typed, drawn or uploaded electronic signature is legally binding for everyday agreements — the US ESIGN Act, the EU's eIDAS regulation and India's IT Act all recognise them. A small number of documents (some wills, certain property deeds and notarised papers) may still require a wet-ink or qualified digital signature, so check local rules for anything high-stakes. For contracts, consent forms, offer letters and the like, a browser signature is normally enough.
After you sign
Sending the signed file onward? If it needs to stay confidential, add a password with the Protect PDF tool before you email it. If it's too large for an upload limit, shrink it with the PDF compressor. And if you need to fill in form fields as well as sign, the Fill PDF tool handles both.
