Most PDF tools require you to upload your sensitive files to a random server. We built a privacy-first alternative. Universal Converters uses WebAssembly to process your documents directly in your browser. Zero Uploads: Your files never leave your device. Zen Mode: A distraction-free interface for deep work. No Limits: Merge, Rotate, and Convert as many files as you want. Also features 50+ engineering calculators for Unit, Weight, and Data conversions.

Build agents & automations integrated across your workspace

Hi everyone! I’m the dev behind Universal Converters. Honestly, I built this because I got paranoid. I needed to merge some tax documents last month, and the idea of uploading them to a 'free' server just didn't sit right with me. I realized that for 99% of PDF tasks, we shouldn't need a server at all. So, I decided to see if I could build a suite that runs entirely in the browser using WebAssembly. The goal was simple: You should be able to load the page, turn off your Wi-Fi, and still get your work done. I think we nailed the privacy part (zero uploads, ever), but I’m still fine-tuning the UX. I’d love your honest take on a few things: The Speed: We claim it's faster because there's no upload/download lag—does it feel snappy on your machine? The 'Zen' UI: I tried to strip away all the ads and clutter you see on other sites. Is it too minimal, or just right? I’ll be hanging out in the comments all day, so please roast my code, suggest features, or just say hi. Thanks for checking it out!
