Stop typing. Start speaking. 4x faster.

Hey Product Hunt! I built ExtConvert out of a real need during tax season — juggling scanned images, merging them into PDFs, compressing them, and protecting files before emailing. Most tools either lacked features, worked only online, or made it too complicated. So I created ExtConvert.com — a simple, all-in-one file conversion tool that works online and offline. You can: Convert docs, audio, video, and archives Merge PDFs and other files Compress files to reduce size Password-protect sensitive files Work offline with downloadable tools I'd love your feedback! 🙌 Let me know what features you’d like next — or if you’ve faced similar file headaches. Happy to chat and improve it further!
