About Audio Tools
Everything CompressKits offers under Audio Tools is listed on this page: Audio Compressor. Each one is a finished tool rather than a demo — you add a file, the page starts from the setting it recommends for that particular file, and the result downloads straight back to you. Nothing is watermarked and nothing waits behind a signup.
Between them these tools read MP3, WAV, M4A, FLAC, OGG, and AAC, and what comes back is MP3, M4A, and OGG. Without an account you can send files up to 500.0 MB, up to 10 of them in a single job, and take the results away one at a time or together as one ZIP. 4 ready-made settings cover the jobs people ask for most, so the manual controls are there for when a result needs adjusting rather than something to work through first.
If you would rather understand the trade-offs before running anything, the Learning Center has 3 guides in this category, among them How to Compress an MP3 File (Without Making It Sound Bad), How to Compress Audio for WhatsApp, and Compress a Voice Recording to Send by Email. Each one ends at the tool it describes, so reading and doing are never more than a click apart.
