Media tools convert, compress, trim and extract audio from video files directly in your browser. Powered by ffmpeg.wasm (WebAssembly), they run entirely on your device — your video is never uploaded to a server, so even private clips stay completely private and the tools are free with no signup.
This cluster covers the everyday media chores creators and developers face: extracting an MP3 soundtrack from a video, converting between MP4, WebM, MOV and MKV, shrinking large recordings with H.264 compression, cutting a short clip by start and end time, turning a moment into an animated GIF, removing an audio track, and converting audio between MP3, WAV, OGG and M4A. Every tool uses the single-thread ffmpeg.wasm build so processing happens locally — no file-size server limits, no privacy trade-offs, and no cost.
Yes. Every media tool on AiTechWorlds is free with no signup, and all processing runs in your browser via ffmpeg.wasm. Your video and audio files are never uploaded to or stored on any server.
No hard limit is imposed, but because everything runs in your browser, very large files (over ~200 MB) depend on your device memory and take longer. For big videos, trim or compress first.
Video: MP4, WebM, MOV, MKV and GIF. Audio: MP3, WAV, OGG and M4A. You can convert between them, extract audio, compress, trim, mute and create GIFs.
These tools use the single-thread ffmpeg.wasm build, which keeps the site fast and ad-supported without special headers. It trades some speed for privacy — nothing leaves your device.
