Lossless formats like WAV store every audio sample exactly as recorded, so nothing is thrown away — the trade-off is large files, roughly 10 MB per minute of stereo CD-quality sound. Lossy formats like OGG Vorbis and WebM Audio use compression that permanently discards data the ear is least likely to notice, which shrinks files dramatically while keeping quality high at normal bitrates. The practical rule is simple: choose WAV when you plan to edit, archive, or feed audio into another editor, and choose OGG or WebM when you need a small file for the web, games, or sharing. This converter lets you move between all three, so you can keep a lossless master and export a compressed copy from the same source whenever a platform or app needs it.

WAV export is nearly instant because the tool writes raw 16-bit PCM samples directly into a file — there's no compression pass, just a straight copy of the decoded audio with a small header. OGG Vorbis and WebM are produced by the browser's MediaRecorder API, which encodes from a live audio stream rather than a static buffer. That means the audio is effectively played through in real time as it records, so a three-minute clip takes about three minutes to encode, and the browser tab must stay active and in the foreground for the entire pass. It isn't a bug or a slow connection — it's how MediaRecorder works. If you only need speed and can accept a larger file, pick WAV. Otherwise, start the OGG or WebM conversion, leave the tab open, and let it finish.

Sample rate is how many audio snapshots are stored each second, and it sets the highest frequencies a file can reproduce. Pick 44,100 Hz for music or anything that should sound full — it's the CD-quality standard and the safe default. Drop to 22,050 Hz for FM-radio-grade voice or speech where a smaller file matters more than sparkle. Use 16,000 Hz only for plain spoken-word clips, transcription pipelines, or low-bandwidth uploads; it's voice-grade and noticeably thinner on anything musical. Lowering the rate shrinks the file but permanently removes high frequencies, so you can't recover detail by converting back up later. As a rule, keep music at 44,100 Hz and reserve 16,000 Hz for speech. Upload your file in this tool, check its original rate in the properties panel, then pick the output rate that fits the job.

The converter reads your file with the browser's Web Audio API, which understands common codecs but not every one. If a file refuses to decode, it's almost always an unusual or DRM-protected codec — purchased tracks wrapped in copy protection, or an exotic container the browser can't open. The fix is to re-export the source as MP3 or WAV in whatever app created it, then load that copy here. A second, separate issue is browser support for the output side: Chrome, Firefox, Edge, and Opera handle OGG and WebM encoding well, while Safari is more limited, so a compressed export may fail there. If that happens, switch the output to WAV, which works everywhere. Between converting the source to a standard input format and falling back to WAV output, almost any decodable file will go through cleanly in this tool.

No — this is a format and sample-rate converter, not a mastering tool, so it changes the container and resolution of your audio without touching its loudness or dynamics. It decodes the source, optionally resamples it, and re-encodes it to WAV, OGG, or WebM, but it won't raise volume, even out levels, or repair distortion that's already baked into a clipped recording. That's by design: keeping the audio untouched means a conversion is predictable and won't introduce new artifacts. If your file is too quiet or already clipping, run it through a dedicated normalizer or compressor first, then bring the corrected version here to change its format. For routine jobs — getting a WAV a DAW will accept, or a small OGG for the web — upload your file above, choose the output format and rate, and download the converted copy.
