How it works

How to fill and sign PDF files

Fill out and sign PDFs securely in your browser. No upload, no servers. Your work auto-saves on your device, so a crash never loses it.

  1. Upload your form. Select or drag-and-drop the PDF document you want to fill and sign.
  2. Add text & signatures. Click to place text blocks, symbols, or signatures on the pages.
  3. Sign with ease. Draw your signature on screen, type it out using a cursive font, or upload a signature image.
  4. Position & resize. Drag items to place them exactly where they belong in the agreement.
  5. Save & download. Click Sign and Download PDF to generate and download your completed document.

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.

Got questions?

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, symbols, 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 stays until you replace the file, or for 14 days if you never come back.

Can I fill and sign a PDF in Hebrew (חתימה על PDF)?

Yes. Hebrew works end to end. Type into a text box and it grows leftward from a fixed right edge, the way right-to-left text actually behaves. The fonts offered for Hebrew are bundled with the tool and checked against their real glyph coverage, so what you see on screen is what gets embedded in the file you download, with no empty rectangles where the letters should be. You can also type your signature in a Hebrew handwriting font rather than drawing it.
