Free, Private Audio & Video Tools That Run in Your Browser

This is a growing set of free online audio and video tools for the everyday jobs — converting audio between formats, extracting the soundtrack from a video, turning a clip into a GIF, and trimming footage down to the part you need. There's no account to create and nothing to install; each tool opens and works right in the page.

What sets these tools apart is that they're privacy-first. All the processing runs on-device using ffmpeg.wasm, so your files are never uploaded to a server — they stay on your computer or phone from start to finish. The interface is mobile-friendly too, so you can convert or trim media straight from your browser wherever you are.

Frequently Asked Questions

Are these audio and video tools free and private? ▼
Yes. Every media tool here is completely free to use with no sign-up, and it's private by design. The audio and video processing happens entirely inside your browser on your own device, so your files stay with you.
Do my files get uploaded to a server? ▼
No. Nothing is uploaded. These tools use ffmpeg.wasm, a version of FFmpeg that runs on-device in your browser. Your audio and video files are read, converted and saved locally — they never leave your computer or phone.
Why does the first run take a moment to load? ▼
The first time you use a media tool, the browser fetches the ffmpeg.wasm engine (about 30MB) once from a CDN. After that it's cached, so subsequent conversions start quickly. All the actual processing then runs locally, with no round-trips to any server.
Are there file size or length limits? ▼
There's no fixed limit we impose, but because everything runs in your browser using your device's own memory and CPU, very large or very long files can be slow or run out of memory — especially on older phones. For big videos, trimming first or working in smaller pieces helps.
Which audio and video formats are supported? ▼
Common audio formats include MP3, WAV, OGG, M4A, AAC and FLAC, and common video formats include MP4, WebM, MKV and MOV, plus animated GIF export. Because these tools are powered by FFmpeg, a wide range of codecs and containers is handled.
Does it work on mobile? ▼
Yes. The tools are mobile-friendly and run in modern mobile browsers on Android and iOS. Keep in mind that phones have less memory than laptops, so large files may process more slowly, but for typical clips it works well on the go.
