Compress WAV recordings to MP3 files up to ten times smaller that play anywhere. Drop a .wav file below and the output is already set to MP3.
1
Drag and drop your .wav file onto the box above, or click Choose Files. The request is already filled in: “Convert this to MP3”.

The AI assistant uses sensible defaults. To choose the bitrate, codec or sample rate yourself, say so in the request, for example “Convert this to MP3 at 320 kbps”.

The assistant opens with your file and converts it on your own device; the file itself is never uploaded. When the MP3 file is ready, click Save. Prefer to set everything by hand, or batch-convert several files into a ZIP? The classic converter is one click away on this page.
A minute of CD-quality WAV is about 10 MB; the same minute as a 192 kbps MP3 is 1.4 MB. Converting WAV to MP3 is the standard way to share recordings, podcasts, voice memos and music mixes by email, WhatsApp or web upload without exhausting storage.
Convertor.video encodes the MP3 in your browser at a bitrate you choose, keeps the sample rate and channel layout, and preserves title and artist tags. Nothing is uploaded, so unreleased mixes stay private.
WAV (Waveform Audio File Format): WAV stores uncompressed PCM audio exactly as it was recorded. It is the standard for audio editing, mastering and archiving, at the cost of large files (about 10 MB per minute of CD-quality stereo). It is best for editing, mastering, DAWs and archiving.
MP3 (MPEG-1 Audio Layer III): MP3 is the universal lossy audio format. It plays on every device made in the last twenty-five years and offers small files with good quality at 192 to 320 kbps. It is best for music players, podcasts, phones and sharing.
In short: keep WAV when the priority is editing, mastering, DAWs and archiving, and switch to MP3 when the file is headed for music players, podcasts, phones and sharing. Need a different target? The full Audio Converter supports every format listed below.
320 kbps for music you care about, 192 kbps for everyday listening, 96 to 128 kbps for speech and voice notes.
WAV rarely stores tags, but you can add title, artist, album and year in the metadata editor before converting.
Yes. Converting WAV to MP3 on Convertor.video is free, with no watermark and no sign-up. The AI assistant runs on a free daily allowance of assistant credits; the classic converter on this page has no daily limit at all.
No. The conversion runs inside your browser using FFmpeg compiled to WebAssembly, so your .wav file is read and converted on your own device and never uploaded, which keeps private recordings private and means there is no waiting in an upload queue. The AI assistant only sees what you type and basic facts about the file: its name, format, duration and size.
There is no plan or account limit, but the converter loads the whole WAV file into your browser's memory, so about 2 GB per file is the practical ceiling; larger files may fail to open. Long or high-resolution files also take longer, especially on phones.
Yes. Ask the AI assistant for a bitrate, codec or sample rate in your request. Audio track selection and every other setting are in the classic converter, one click away on this page.
MP3 is a lossy format, so the WAV audio is decoded and re-encoded. Keep the bitrate at 100% (or pick 256 to 320 kbps) and the difference is inaudible for almost all listeners.
It is built and tested on current desktop Chrome and Edge. The conversion itself runs in WebAssembly, which every current desktop browser supports, so speed depends mostly on your computer's processor.
