Questions

Is my PDF uploaded anywhere?

No. The file is opened, signed and saved inside your browser. It never leaves your device, and the tool keeps working with no internet connection once the page has loaded.

Is it really free?

Yes. There is no account, no watermark and no limit on files or pages. Sign as many documents as you like.

Is a signature added this way legally valid?

In the US, UK, EU and many other places, an electronic signature is valid for most everyday documents, like leases, forms and agreements, when everyone agrees to sign electronically. Some documents, such as wills, may need a witnessed or certified signature, so check if you are unsure.

Where is my signature saved?

Only in this browser on this device, so you can reuse it next time with one click. Use "Forget my saved signature" to remove it.

Can I add the date, initials or a checkmark?

Yes. Use the toolbar to add your initials, today's date, any text or a checkmark, then drag and resize each one to fit the form.

Also free: QR codes that never expire, with no sign-up or watermark.
