Zero-Trust Security by Design

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.

No Upload Bottleneck

Uploading a 500 MB video on a standard 15 Mbps residential connection takes 4.5 minutes just to begin converting on CloudConvert. MixConvert reads files straight from your SSD into local RAM in milliseconds, executing encoding at raw hardware speeds.

No Paywalls or File Size Caps

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.
