Most online PDF services upload your file to their servers to process it. StampAPDF is different: the work happens inside your browser using modern web technology. Contracts, invoices, and ID documents stay exactly where they belong — with you.
Yes — every tool is completely free with no page limits, no trial, and no watermarks added to your files. The site is supported by ads.
No. All PDF processing happens locally in your browser using JavaScript. Your documents never leave your device, which makes StampAPDF a good fit for contracts, invoices, and other sensitive files. Only the signature/stamp images you choose to save in your library are stored, so they're available next time.
Open the Stamp & Sign tool, upload your PDF, add your signature image to the library once, then click where you want it on the page. Drag to move, resize with the corner handle, and download the signed PDF.
No signup is needed for any tool. You can save signature and stamp images to a library so they're ready to reuse on your next document.
Yes — everything runs in a normal web browser on Windows, Mac, Linux, Android, and iPhone. No app to install.
Those services upload your file to their servers for processing. StampAPDF does everything in your browser, so your documents stay private, and there are no daily task limits.
Free forever. No signup. Your next signed document is 30 seconds away.
