100% private, browser-based PDF signing. Free & serverless.

I’m Ali,

the creator of MyDigitSign.

Like many of you, I sign a lot of agreements. NDAs, client contracts, lease papers—you name it. But every time I uploaded a sensitive PDF to a random online signer, I felt uneasy. Where do my files go? Who is hosting them?

On top of that, most tools lock basic features behind a paywall or force you to sign up just to place one signature.

I wanted a simple, secure alternative. So, I built Sign PDF online.

Here is the magic: It is 100% browser-based.

Your PDFs never touch our servers. Everything runs locally in your browser using WebAssembly. Your files are completely safe because they never leave your device.

What you can do:

• Edit and sign PDFs online: Drag, resize, and place signatures anywhere on your document.

• Create a free digital signature certificate: Type your name using elegant cursive fonts, draw your signature, or upload an image.

• 100% Serverless & Free: Zero account creation. Zero paywalls.

• Legally Binding: Complies with ESIGN Act and eIDAS guidelines for everyday agreements.

I’d love to hear your thoughts! Are electronic signatures acceptable for your daily business? What other PDF tools should we build next?

Thank you for the support! 🚀
