Rellenar y Firmar un PDF

Dibuja o escribe tu firma, y colócala sobre la página.

Cómo funciona

Sube tu PDF, dibuja o escribe tu firma y se colocará automáticamente sobre la página — arrástrala para reposicionarla. Si el PDF tiene campos de formulario rellenables, se detectan y se muestran directamente en la página para que los completes. Descarga el resultado cuando termines.

¿Puedo dibujar mi firma con el ratón, y no solo con pantalla táctil?

Sí — el panel de firma funciona con ratón, trackpad o pantalla táctil.

¿Puedo firmar más de una página?

Esta herramienta coloca una firma por descarga. Para varios lugares de firma, descarga el archivo firmado y vuelve a pasarlo por la herramienta para la siguiente página.

Can I resize my signature after placing it?

Yes — drag its corner handle to resize it, and drag the signature itself to reposition it before downloading.

Does this work if the PDF has no fillable form fields?

Yes — you can still place a signature anywhere on the page even without detected form fields; fields are just an added convenience when present.

Is a signature added this way legally binding?

That depends on your jurisdiction and use case — this tool places a visual signature image on the page; it doesn't provide cryptographic e-signature certification. Check your specific legal requirements before relying on it for contracts.

Can I type my signature instead of drawing it?

Yes — switch to Type mode, type your name, and it renders in a cursive-style font that's ready to place on the page, no mouse or touchscreen drawing needed.

Can I upload a photo or scan of my actual signature?

Yes — switch to Upload, drop in a PNG or JPG of your signature (a photo of one you signed on paper works fine), and it places on the page the same way as a drawn or typed one.

Can I add a date or my printed name next to my signature?

Yes — the Add Text mode lets you type any short text and place it anywhere on the page, separate from your signature. Handy for a date, printed name, or initials next to where you sign.

Does it save my signature so I don't have to redo it next time?

No — nothing is uploaded or stored anywhere. Everything runs in your browser, so once you close the tab it's gone. Draw, type, or upload it again next time you need it; it only takes a few seconds.

I need a real digital signature, not just a signature image — what should I use?
