Why Use Browser-Based Video Tools?
Traditional video converters require uploading your files to a server, waiting for processing, and then downloading the result. This is slow, raises privacy concerns, and often comes with file size limits or usage caps.
tconv.com uses FFmpeg compiled to WebAssembly (WASM) to process video files entirely in your browser. Your files never leave your device. This means:
- Complete Privacy - No file uploads, no server storage, no data collection
- No Waiting - Processing starts instantly, no upload/download queue
- No Limits - No daily file limits or registration requirements
- Works Offline - Once loaded, tools work without internet connection
