¿Qué es el Firmar PDF?
Firmar PDF is a free online tool that dibujar, escribir o subir una firma a un PDF.
Signing a PDF should not mean guessing where your signature lands or paying for a subscription. This free Sign PDF tool shows a live preview of every page so you can place signatures exactly where they belong — on the signature line, bottom of a contract, or any page you choose.
Create your signature three ways: draw with mouse or touch, type your name in a script font, or upload a PNG/JPG image. Drag signatures into position, resize with the corner handle or width slider, adjust opacity, and add an optional date stamp.
Need the same signature on every page? Place once and copy to all pages, or use the “place on all pages” option. Save signatures in your session for quick reuse across multiple documents.
Everything runs 100% in your browser on Mytulify — your PDF and signature never leave your device.

Yes. Navigate between pages and place signatures on each one, or use “Place on all pages” / “Copy to all pages” for the same signature everywhere.
Is my PDF uploaded to a server?
No. The entire signing process runs in your browser — your document and signature stay on your device.
Can I type instead of draw a signature?
