Free audio compressor
Drop an audio file, or drop a video and we extract the audio. We compress it to MP3, small enough for any email, chat, or archive.
Choose how to compress
From inbox-blocking to pocket-sized
Real files, real targets. Video gets its audio extracted first, then we shrink that to fit anywhere.

23.6× smaller, same audio, different trip
Three steps, no knobs to tweak
Drop a file, pick a size, keep the result. We handle everything in between
Drop the file
Any audio or video up to 5 GB. If it's a video we automatically extract the audio track and compress that. The video is discarded.
Pick a preset
Email, chat, archive, or max. Each preset targets a size vs. clarity tradeoff. We default to voice-safe.

Email attachments
Under 25 MB, every timeGmail, Outlook, iCloud Mail. Nearly every provider caps attachments at 25 MB. The Email preset targets ~5 MB per hour of audio, so even a long interview slips through
Chat & DMs
WhatsApp, Slack, TelegramChat apps compress everything you upload anyway. Give them a pre-compressed file and you keep control of the output. No mystery bitrate, no mystery loss
Long-term archive
Keep the years, not the gigabytesA decade of meetings at 128 kbps is a few gigs, not a few terabytes. Archive preset keeps every word legible while shrinking storage 10× or more
