Legacy converters claim to delete files after 24 hours, but your data is still transmitted unencrypted or stored on shared multi-tenant clouds. MixConvert never uploads your file in the first place. Confidential NDA documents, financial spreadsheets, and personal photos never leave your device.
Uploading a 500 MB video on a standard 15 Mbps residential connection takes 4.5 minutes just to begin converting on Convertio. MixConvert reads files straight from your SSD into local RAM in milliseconds, executing encoding at raw hardware speeds.
Cloud converters enforce 100 MB caps because server CPU time and bandwidth cost money. Because MixConvert leverages your own browser's WebAssembly engine, we incur zero server compute overhead — passing unlimited, unmetered conversions to you for free forever.
Why Server-Based File Conversion (Like Convertio) Is Obsolete
When Convertio launched in 2014, web browsers were incapable of heavy computation. Users had no choice but to stream multi-megabyte files across the internet to centralized Linux server farms, wait in queue for processing, and download the finished artifact.
Today, modern browsers running on Apple Silicon, modern Intel/AMD processors, and mobile chipsets possess incredible compute power. With WebAssembly (WASM), native C and C++ codecs from FFmpeg, libheif, and PDF engines run directly on your hardware at near-native execution speed.
This shift makes uploading your sensitive company documents, client contracts, private audio recordings, or high-resolution videos to Convertio not only slow, but an unnecessary security vulnerability. With MixConvert, you achieve instant execution without surrendering file custody.
