About this app

Reduce audio file size in seconds with Audio Compressor. Compress MP3, WAV, FLAC, M4A, AAC, OGG and WMA files right on your phone to free up storage and make songs, voice notes, podcasts and recordings easier to send.

OFFLINE AND PRIVATE
Everything runs on your device. Your audio is never uploaded to a server, and the app works without internet. You pick each file yourself, and no storage permission is needed.

AUDIO COMPRESSOR FOR EVERY COMMON FORMAT
• MP3 compressor: shrink songs, ringtones and recordings
• WAV compressor: large WAV files become small M4A files, or keep WAV
• FLAC compressor: save space on lossless music, as M4A or keep FLAC
• M4A, AAC, OGG and WMA compressor
• AIFF and AIF support

CHOOSE HOW SMALL YOUR FILES GET
• Quality scale from 1 to 10 for a quick result
• Bit rate up to 512 kbps, by slider or exact value
• Sample rate: keep the original or choose 8,000 to 48,000 Hz
• Channels: original, mono or stereo (mono is about half the size and works well for speech)
• Normalize volume so quiet and loud files sound even
• Fade in and fade out up to 30 seconds

BATCH AUDIO COMPRESSION
Compress many files at once and mix formats in the same batch: MP3, WAV, FLAC and more. Remove any file from the list before you start.

SEE THE RESULT BEFORE YOU SAVE
• Original size, new size and percent saved for every file
• Total space saved for the whole batch
• Play the audio before and after compression
• Save all files into a folder you choose

GREAT FOR
• Freeing up phone storage used by music and recordings
• Making voice notes, podcasts and interviews smaller
• Shrinking large WAV and FLAC recordings
• Reducing the size of lectures and audiobooks with mono

HOW TO USE
1. Tap the select files button and select your audio files
2. Choose Quality or Bit rate, plus any extra options
3. Tap Start Compressing
4. Preview the results and save them to your phone

A NOTE ON QUALITY
Smaller files come from a lower bit rate. At higher settings the difference is hard to hear, and at lower settings you save more space. You choose the balance. Files that are already highly compressed may shrink only a little, and the app shows the real result before you save.

FREE TO USE
Audio Compressor is free and supported by ads. Single-file compression is always available. Batch compression is unlocked by watching a short ad.

Ratings and reviews

It was simple and easy to use and did exactly what I wanted! I downloaded two similar apps that could not do what I wanted, were not user-friendly, and were full of ads. This app, however, was my saving grace. It compresses audio and MP3 files perfectly, delivering exactly what it promised! The best MP3 compressor I’ve found!

It's a good app as it can help reduce recorded sound size and compress it which not only saves more space in the phone but also can allow the audio to be shared like on Whatsapp platforms, to mention when it's not much space consuming.

It has been a wonderful app for audio compression. I recommend it 24 hours a day and 7 days a week.
