How it works?
100% Private Conversion in Your Browser
Unlike most online converters, ConvertMedia works entirely in your browser. Your files never leave your device and are not uploaded to our servers.
Step 1: Select a file
Drag and drop a file into the converter window or click to select. We support all popular audio and video formats: MP4, MP3, WAV, FLAC, WebM, AVI, MOV and many more.
Step 2: Choose format
Select the format you want to convert to. You can also adjust quality, bitrate and number of channels (mono/stereo) for precise customization.
Step 3: Conversion happens locally
After clicking the "Convert" button, all processing happens right in your browser using WebAssembly technology. The file is not uploaded to the server - everything stays on your device.
Step 4: Download result
When conversion is complete, simply download the finished file. You can immediately convert the next file if needed.
WebAssembly Technology
ConvertMedia uses WebAssembly - a modern technology that allows running high-performance code directly in the browser. This means:
- Privacy: Your files never leave your device
- Speed: No delays for uploading and downloading files from the server
- Security: No one has access to your files
- No limits: Convert files of any size
