Compresor de WAV online

What Compresor de WAV does

Audio compression here means saving the same recording with less data. For MP3 files, Compresor de WAV re-encodes the sound with the LAME encoder at a lower bitrate. For WAV files, the result stays an uncompressed WAV, and the size goes down by lowering the sample rate, the number of channels or the bit depth.

Each of these steps removes information, so the aim is to remove only what listeners will not miss. Typical targets are voice notes, podcasts, lectures and sound effects that must fit an upload or email limit.

Cómo usar Compresor de WAV

1. Arrastra los archivos que quieres reducir.
2. Elige un nivel de compresión o deja el ajuste recomendado.
3. Haz clic en Comprimir y compara el tamaño anterior con el nuevo.
4. Descarga los archivos más ligeros.

When to use Compresor de WAV

• Make a long podcast or lecture MP3 small enough to send by email or post on a site with an upload limit.
• Reduce WAV voice recordings from a field recorder before archiving hundreds of interviews on a shared drive.
• Prepare short WAV sound effects at 22050 Hz mono for a game, an app or a device with little memory.
• Shrink an audiobook chapter to 64 kbps mono so it takes less space on a phone or an old MP3 player.

Settings explained

Bitrate

For MP3 files, sets the new bitrate from 32 to 160 kbps. The default of 96 kbps is clear for speech. Use 128 or 160 kbps for music, and 32 or 48 kbps only for voice.

Mono

Mixes left and right into one channel. For WAV files it is on by default and halves the size. For MP3 files it is off by default and makes speech clearer at low bitrates.

Sample rate

For WAV files, sets how many samples are stored per second. 44100 Hz is CD quality, the default of 22050 Hz is fine for speech, and 8000 Hz sounds like a telephone line.

Bit depth

For WAV files, chooses 16-bit or 8-bit samples. 16-bit, the default, sounds clean. 8-bit halves the size again but adds audible hiss, so use it only for simple sound effects or retro projects.

¿Qué es WAV?

WAV (Waveform Audio File Format) es un formato de audio creado por Microsoft and IBM en 1991. Usa compresión sin pérdida. Los archivos usan la extensión .wav.

WAV is an audio file format from Microsoft and IBM based on the RIFF container. It usually stores uncompressed PCM audio, the same type of data used on audio CDs, so every sample is kept exactly. Its file size depends only on the sample rate, bit depth, number of channels and duration.

WAV is the right choice for recording, editing and mastering audio, for sound effects in software and games, and as a master copy before you create MP3, AAC or other compressed versions.

Uncompressed WAV files are large, about 10 MB per minute for CD quality stereo. A standard WAV file cannot be larger than 4 GB. Support for tags such as artist and album is weak compared with MP3 or FLAC.

WAV plays in all major web browsers, on Windows, macOS, Linux, Android and iOS, and in every audio editor and digital audio workstation. Some hardware players and car stereos do not support it.

Sin colas, sin marcas de agua y sin cuenta. Una vez cargada la página, la herramienta sigue funcionando incluso con una conexión lenta.

Tips for the best result

• WAV sizes are easy to predict: 44100 Hz stereo 16-bit uses about 10.6 MB per minute, and 22050 Hz mono 16-bit uses about 2.6 MB.
• If you need much smaller audio than WAV allows, convert to MP3, M4A or OPUS with the audio converter instead. Lossy formats are far more efficient.
• Compressing an MP3 that already has a low bitrate rarely helps. If the result would be larger than the original, you get the original file back.
• Listen to part of the result before deleting anything, and keep the original recording in case you need higher quality later.

How Compresor de WAV works in your browser

Video and audio are processed with FFmpeg, the open-source media toolkit behind most video software, compiled to WebAssembly. Video is encoded with H.264 for MP4, MOV and MKV, VP8 for WebM, and audio with AAC, MP3, Vorbis, Opus or FLAC depending on the format.

WebAssembly FFmpeg runs on your device's processor without a server. It is slower than a native desktop app, so a long video can take a few minutes. Keep the tab open until the progress bar finishes.

Privacy and security

Most online converters upload your files to a server, process them there and keep a copy for some time. Compresor de WAV works differently: the code is downloaded to your browser once, and your files are read and written only on your device.

You can check this yourself: after the page has loaded, turn off your internet connection and the tool still works. This makes it safe for contracts, IDs, medical records, private photos and unreleased work.
