Free for everyone

Fill and sign as many PDFs as you like, with no account, no watermark, and no page limits. Because signing runs on your device, your signature and file are never uploaded, and your progress auto-saves locally so a crash never loses your work.

It's open source under the MIT license, so anyone can read the code, fork it on GitHub, or share it. Simple PDF tools should be free for everyone.

Frequently asked questions

Do I need to create an account to sign a PDF?

No. There is no signup, no email verification, and no trial period. Open the tool and start signing immediately.

Can I sign school trip agreements?

Yes. This tool is perfect for child school trip agreements, consent slips, and standard PDF forms. You can type the child's name, tick the consent checkboxes, and draw your parent signature.

Is my signature safe here?

Yes. This tool runs entirely on your device, so there is no account and no server-side copy of your document. Your signature image is embedded in the PDF in-memory and never leaves your computer or phone.

Can I type my signature instead of drawing?

Yes. If you don't want to draw with a mouse or touch, you can select the "Type" option. It renders your name in a handwriting font and embeds it as a signature.

What happens if my browser crashes while filling out a form?

Your work is not lost. As you add text, checkmarks, and signatures, the tool auto-saves your progress to local storage in your own browser, and restores it automatically the next time you open the tool on the same device. Because this happens on your device, your file is still never uploaded, and your saved draft is only cleared when you click Start over.
