Upload your PDF, choose the page where the signature goes, draw it with your mouse or finger (or type your name and it becomes a handwritten signature), drag it to the exact spot and adjust the size. When you click "Sign and download", the final PDF is generated with your signature already embedded. Everything happens in your browser: the document is never uploaded to any server.
Frequently asked questions
Are my files uploaded to any server?
No. The whole process happens in your own browser, so your files never leave your device: they're not uploaded, not stored, and nobody sees them.
Is it free? Are there any limits?
Yes, it's free, with no watermarks and no sign-up. The free plan supports files up to 10 MB (and up to 5 at a time in the tools that combine several PDFs); MásPDF Pro removes those limits.
Do I need to install anything or create an account?
No. It works right in your browser, on desktop or mobile. You can also install it as an app and use it offline.
Is the signature legally valid?
It's a handwritten signature placed on the PDF, valid for most everyday uses. For official procedures that require a digital certificate, a different method is used.
