Why I Built ConvertFree4U
Tired of subscriptions, paywalls, and slow uploads.
I got incredibly frustrated every time I just needed to quickly turn a WebP image into a PNG. Every tool I found either slammed me with a daily limit, demanded me to create an account, or—worst of all—forced me to upload my private photos to their random servers. So I built ConvertFree4U to solve my own problem using modern web technology where the processing happens right inside your browser. No middleman, no servers, no nonsense.
Truly Private
I literally do not own a server to store your files. Your browser does all the heavy lifting locally.
Actually Free
No "Pro" versions. Convert as many files as you want, as large as your device can handle.
Modern Under the Hood
Built with WASM and Web Workers so your browser can process files almost as fast as a native app.
