Free browser-based media tool
Seven output formats from one tool. MP3 and M4A stay small for sharing, WAV and FLAC keep the samples that are present in the source, and OGG/Opus is efficient for web playback.
Best for turning M4A voice memos into MP3, converting a FLAC download into something you can send, or exporting a clean audio track from a video file.
Convert audio online for free with no watermarks. Turn MP3, M4A, WAV, FLAC, OGG and AIFF files into each other in your browser, and pull the audio track out of a video file in the same place.
Yes, the audio converter is free to use. There is no registration required, no login needed, and no subscription fees, and the exported audio carries no watermark or advertising tag. The practical limit is your browser memory.
You can export MP3, M4A (AAC), WAV, FLAC, OGG (Opus), OGG (Vorbis) and AIFF. On the input side the tool reads those formats plus the audio tracks inside common video containers such as MP4, MOV, MKV and WebM, so you can also use it to pull audio out of a video.
MP3 and M4A are lossy: they discard audio detail to make files small, and MP3 is the most universally supported. FLAC is a lossless format — smaller than WAV, but able to reproduce the current samples exactly. WAV stores uncompressed PCM, so it is the largest but the simplest to edit. OGG/Opus is lossy and efficient at low bitrates, which suits web playback.
No. Once a lossy encoder has discarded detail, that detail is gone; a higher bitrate only avoids adding further damage, it cannot restore what was removed. If you must re-encode, going from a low bitrate to a higher one mostly increases file size. Keeping the source untouched is the only way to preserve its current quality.
