This was the first app that people actually wanted: How to Convert. It’s a file converter that runs entirely on your own machine. Nothing gets uploaded to the cloud like every other file converter you find on Google.
Drag and drop to convert videos, images, audio, emails, and documents locally. Convert HEIC to JPG, MP4 to MP3, Word to PDF, shrink your file size and more. Try the demo or scroll to see why you should get the app.
All files are converted in the browser and do not leave your device. Use the app for offline conversions.
I wanted to know what was slowing my Mac down without opening Activity Monitor. This app lets you see everything that’s happening on your Mac in a single line in the menu bar.

If you’ve bought How to Convert (my file converter app), I’d love your honest feedback. I’ve been building it for 1.5+ years and I’m ready to make the jump to v2. What’s one feature you’d love to see, or are still waiting for? Almost every great feature in the app has come from someone here suggesting it 👇
My file converter app has had 185,000 site visitors and earned $85k. I built it before vibe coding was a thing. Despite a mountain of AI-generated clones popping up, it's still doing well.
My file converter app has had 185,000 site visitors and earned $85k. I built it before vibe coding was a thing. Despite a mountain of AI-generated clones popping up, it's still doing well. Two reasons why: It runs completely locally (your files never touch a server like every online converter) Supports almost any file type (5,438 document, video, image and audio conversions instead of just images, video or just docs) Started as a side project. Now it takes up almost all my time.
I got sick of uploading my files to random sketchy sites on Google So I made a file converter app that runs completely locally It supports almost any file type (does over 5000 document, video, image, audio, email and comic conversions) And just crossed 2,670 users!
This is an app I made. It turns your screen recordings into demos that look like an Apple ad I launched it just over a month ago, and it now has 225 users
