Compress Audio — Shrink MP3 & M4A Free, In Your Browser
Drop your audio files, pick a bitrate, and download smaller MP3 or M4A files — compressed in your browser, nothing uploaded.
Drop a file or click to choose
Drop as many as you like — they compress in your browser, then download as one zip.
Eziclip is a free, in-browser audio compressor: drop one or many MP3, M4A or WAV files, pick Small, Balanced or High, and download them — as a zip if there's more than one. It re-encodes to MP3 or AAC at a chosen bitrate entirely on your device, so nothing is uploaded, there's no watermark and no sign-up. Unlike cloud converters like CloudConvert or Online Audio Converter that upload your files and cap the free tier, Eziclip compresses locally.
Shrink audio for sharing and storage
A WAV recording or a high-bitrate export can be large — slow to upload to a podcast host, heavy in email, and bulky to archive. Compressing to MP3 or AAC at a sensible bitrate cuts the size dramatically while keeping the audio clear, especially for speech.
Eziclip compresses audio entirely in your browser. Drop one file or a whole batch, pick a level, and each is re-encoded on your own device — no upload, no per-file limit, no watermark.
Pick a bitrate level + format
Three levels map to common bitrates: Small (96 kbps) for the smallest files and voice, Balanced (160 kbps) for a clean all-round result, and High (256 kbps) to stay close to the source. Choose MP3 for maximum compatibility or M4A (AAC) for a slightly smaller file at the same quality.
Each file shows its before and after size and the percent saved, and you can play the original and the compressed version to compare. Your originals are never changed — re-compress at a different level any time.
Private and free
Cloud audio tools upload every file to a server to convert it. Eziclip never uploads — the encode runs on your device, so your recordings stay private and there's no cost per file, which is why it's free with no caps and no watermark.
Free the whole way through: no account, no watermark, no paywall at the download. Like every Eziclip tool, it's funded by optional support.

Questions
Yes — every level and every download is free, with no watermark, no account and no file limit, because the encoding runs on your device, not a server.
No. Compression runs entirely in your browser — your files never leave your device and there's nothing for any server to keep.
MP3 is the most compatible everywhere. M4A (AAC) usually gives a slightly smaller file at the same quality. Both work for voice and music; pick MP3 if you're unsure.
For speech and podcasts, Small (96 kbps) is usually plenty. Balanced (160 kbps) is a safe all-round choice; High (256 kbps) stays closest to a music source. You can compare sizes before downloading.
Yes — drop as many files as you like; they compress one after another and download together as a single zip.
