How it works
-
1
Upload your file
Click the upload area or drop the file onto the page. Tools that accept multiple files let you select them all at once.

2
Draw or upload your signature
Draw with your mouse or finger, type a name in a signature font, or upload a transparent PNG of your existing signature.

3
Run the operation
Press the action button when you are ready. Sign PDF runs in the background; a typical file finishes in seconds.

Download the result
The download button appears as soon as the output is ready. The link stays valid for one hour, after which the file is removed from our servers.
Frequently asked questions
Yes. Sign PDF is available on the free plan. Free accounts have a limit of 2 operations per hour and 5 MB per file. Pro removes the hourly cap and raises the file size limit to 500 MB.
All uploads go over HTTPS. Snappdf processes the file, returns the result, and deletes both the upload and the output from our servers within one hour. We do not read, share, or sell your file contents.
Free accounts can upload files up to 5 MB. Pro accounts handle files up to 500 MB. In batch jobs, each file is subject to these limits individually.
No. Snappdf runs entirely in your browser; there is nothing to download or install. The optional Chrome extension adds one-click access to PDFs you encounter on the web.
