Fill and Sign PDF is a browser-based tool that lets you complete PDF forms and add digital signatures without printing, scanning, or installing any software. You can add text, draw or type a signature, insert checkboxes, and stamp the current date — all directly on your PDF document.
Our tool uses pdf-lib, a powerful JavaScript library, to embed your annotations directly into the PDF structure. This means your signed document looks exactly the same in any PDF viewer — no overlays, no workarounds, just a properly signed PDF ready to send.
Because everything runs locally in your browser, your PDF is never uploaded to any server. This makes our Fill & Sign tool one of the most privacy-respecting options available online.
Upload your PDF using the button above or drag and drop it onto the upload area. On the next page, you'll see your PDF displayed with a toolbar on the right. Select the tool you want (Text, Signature, Date, Checkbox, or Initials) and click anywhere on the PDF to place it. Once you're happy with all annotations, click Apply & Download to generate and download your signed PDF.
Digital signatures save significant time compared to the traditional print-sign-scan workflow. A document that would take 30 minutes to print, sign, scan, and email can be completed in under 2 minutes with an online signing tool. This is especially valuable for contracts, application forms, consent forms, and any other document requiring a signature.
Digital signatures are legally recognised in most jurisdictions for everyday agreements. They are also eco-friendly — no paper, no ink, no physical mail required. For businesses, digital signing reduces administrative overhead and accelerates turnaround times on important documents.
Three simple steps — no software, no account, no uploads retained.

Yes. pdf-lib embeds your annotations directly into the PDF as standard PDF objects, so the signed document will display correctly in any PDF viewer including Adobe Acrobat, Preview, and Chrome.
Yes. Our tool overlays annotations on top of your PDF. For PDFs with AcroForm fields, you can add text and signatures on top of the existing form. Note that we add visual annotations rather than filling interactive form fields programmatically.
Your signed PDF is only stored in your browser's temporary memory (sessionStorage) while you're on the tool pages. It is automatically cleared when you close the tab or navigate away.
