Frequently asked questions
Which audio formats are supported?+
You can convert between MP3, WAV, OGG, AAC, FLAC, and WebM. Any combination of input and output format is supported in a single batch.
Does converting audio reduce its quality?+
Converting to a lossy format like MP3 or AAC at a lower bitrate will reduce quality. Converting to a lossless format like FLAC or WAV preserves the full audio fidelity of the source file.
Can I convert several files at once?+
Yes. Batch conversion is fully supported. Add all your files, pick the output format and settings, and every file converts in parallel.
Are my audio files sent to a server?+
No. All audio processing runs in your browser using WebAssembly. Your files are processed locally on your device and never uploaded anywhere.
Is there a file size limit?+
There is no fixed server limit since everything runs locally. Very large files depend on your device memory and browser capabilities. Most files under a few hundred megabytes convert without issues.
