Free Online Audio Converter
The converter decodes your file with the browser’s audio engine, resamples it to the rate you choose, and re-encodes it to MP3 (small and universal) or WAV (lossless). Because it all happens on your machine, the original never leaves your device.

Questions about Audio Converter
Which input formats can it read?
Anything your browser can decode — commonly MP3, WAV, OGG, M4A/AAC and FLAC. Some DRM-protected or unusual codecs are refused by the browser itself.
Why is my MP3 smaller than the WAV?
MP3 is lossy compression; WAV stores every sample uncompressed. For voice and sharing, MP3 at 128–192 kbps is usually plenty; choose WAV for a lossless master.
About Audio Converter
Convert audio between MP3, WAV and OGG with our free online Audio Converter. 100% browser-based, fast, and private—no login or file uploads required.
These audio tools edit sound without a desktop editor: trim and join clips, convert formats, record from microphone, and adjust volume, speed, pitch or equalisation while you listen to the result.
This tool runs in your browser. The file is not uploaded. Work on a copy and preview before downloading: trimming and speed changes are destructive to the loaded clip, and re-encoding a lossy file twice adds audible artefacts.
