Hey Product Hunt! 👋 I'm Asad, the maker of SignifyPDF. I built this because I was frustrated with the current state of PDF tools. Every time I needed to quickly sign an NDA, tax form, or contract, I was forced to either pay a ridiculous subscription fee to Adobe/DocuSign, or upload my highly sensitive personal documents to a sketchy "free" PDF website. I realized this process shouldn't require a cloud backend. So, I built SignifyPDF to be 100% local-first. When you drag your PDF into the app, all the rendering and signing happens locally in your browser using JavaScript. Your files never touch a server, meaning your data stays completely private. It's entirely free, open-source, and has zero watermarks. Just drag, drop, draw your signature, right-click to place it, and download. I would absolutely love your feedback on the drawing experience or any feature requests you might have! Let me know what you think! 🚀

Why do we still upload sensitive PDFs to the cloud just to sign them?

Hey everyone! I'm gearing up to launch SignifyPDF tomorrow, and I d love your thoughts on something.

While building this, I realized how normalized it has become to upload highly sensitive documents (like NDAs, tax forms, and job contracts) to random "free" PDF signing websites just to draw a quick signature on them. Most of these sites process the file on their backend, which means your data is sitting on a server somewhere.

I built SignifyPDF to completely bypass the server. It s a 100% local-first, in-browser PDF signer. You drag the file in, sign it, and download it instantly without the file ever leaving your computer.
