Three ways to add your signature

Draw your signature

Use your mouse or trackpad to draw your signature freehand in the signature box. On a phone or tablet, use your finger or stylus. This produces the most natural-looking result and closely matches a pen-and-paper signature.

Best for: any device, most natural appearance

Type your name

Type your name and PDFree renders it in a cursive signature-style font. Quick and consistent — the same signature every time. Legally equivalent to a drawn signature in most jurisdictions.

Best for: speed and consistency

Upload a signature image

Sign your name on paper, take a photo or scan it, and upload it as a PNG with a transparent background. This gives the most authentic appearance if you need your signature to match exactly what's on file with a bank or institution.

Best for: matching an existing institutional signature

What if the PDF has no form fields?

Some PDFs look like forms but are actually flat — printed forms scanned or exported as images, with no interactive fields. You can still fill them in PDFree by placing text boxes manually:

  1. Load the PDF in the Fill tool
  2. Click the "Text" tool to add a text box anywhere on the page
  3. Click where the blank line is and type your answer
  4. Position the text box precisely over the field using drag
  5. Add your signature the same way — click to place, then drag to position

Frequently asked questions

How do I fill a PDF form and add my signature for free?

Open pdfree.io/fill/, load your PDF, click each field to fill it, then use the signature tool to draw, type, or upload your signature. Click Download when done. No account, no upload.

Can I fill a PDF that has no interactive fields?

Yes — use the text tool to click anywhere on the page and type. Works on flat PDFs, scanned forms, and any PDF without built-in form fields.

Is my signature saved or stored?

No. Your signature is created and embedded entirely in your browser session — never sent to any server. Once you close the tab, no trace of it remains anywhere outside your downloaded file.

Is an electronic signature legally valid?

In most countries, yes — for everyday documents like employment forms, rental agreements, and consent forms. eIDAS (EU), ESIGN (US), and equivalent laws in the UK, Canada, and Australia recognise electronic signatures. For high-stakes filings or notarised documents, verify the specific requirements.

Can I sign without printing and scanning?

Yes — that is exactly what this tool is for. Draw your signature with a mouse or finger, type your name in signature style, or upload a photo of your handwritten signature. No printing, no scanning, no fax required.
