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! 🚀
