About WAV to MP3 conversion
WAV is an uncompressed linear PCM format encapsulated in the RIFF container, commonly used as a standard intermediate format for audio editing and recording. Its file size is approximately 10 times that of an MP3 with the same content. MP3 is a lossy perceptual coding standardized in 1993, all of its patents expired in 2017, and it is universally compatible with all playback devices. Users convert WAV to MP3 mostly to reduce file size and adapt to general playback scenarios.
This conversion is processed via the FFmpeg engine. The output MP3 bitrate supports custom adjustment between 64kbps and 320kbps, and the output file size can be reduced to about one-tenth of the original WAV. The sample rate and channel count of the original WAV are preserved, and the ID3 metadata tags contained in the original audio can be fully carried over to the output file.
The converted MP3 can be played directly on various playback devices such as mobile phones and computers. It is suitable for scenarios including personal music storage, online audio sharing, and embedding into documents for presentations. If you need WAV for audio editing, it is not recommended to convert the obtained MP3 back to WAV for use.

FAQ about WAV → MP3
Will the sound quality decrease after conversion
Sound quality will change. WAV is an uncompressed format, while MP3 uses lossy perceptual coding. When outputting at the high 320kbps bitrate, subjective sound quality differences are difficult to perceive. Output at lower bitrates leads to more noticeable sound quality degradation.
Will metadata be preserved
The ID3 metadata tags contained in the input WAV can be fully preserved in the output MP3 file after conversion. Common information including track name, artist, album and other details will not be lost.
What is the single file size limit
The maximum single file size for conversion on this site is 50MB, and only one file can be converted per conversion task. Files exceeding the limit cannot be submitted for processing. The service is free of charge, the output has no watermarks, and no account registration is required.
Will you keep my files after conversion
Conversion is completed on the server side. Files are uploaded to the server via HTTPS. After conversion is completed, the server immediately deletes both the source file and the output file, and does not store any files.
