Questions
Before you dive in
Are all these video tools free?
Yes. All 18 video tools are completely free with no limits, no account, and no watermark on your output.
Do my video files get uploaded to a server?
No. Every tool uses FFmpeg.wasm, a WebAssembly build of FFmpeg, running inside your browser tab. Your video never leaves your device.
Why does the first video tool take longer to load?
The first tool you use downloads FFmpeg.wasm, about 25MB. Your browser caches it, so every video tool after that starts instantly.
Is there a file size limit?
No enforced limit, but very large or long videos may process slowly or use a lot of memory, since everything runs on your own device.
How do I convert MOV to MP4 for free?
Open the MOV to MP4 tool, drop your iPhone or Mac recording, and download the MP4. Both formats usually share the same video and audio codecs, so this is typically a fast conversion with no quality loss.
How do I extract audio from a video?
Open one of the Extract Audio tools, drop your video, and download the audio track as MP3, WAV, AAC or OGG. It runs in your browser, so the video is never uploaded.
