Trim a video clip, extract the audio, turn a short segment into an animated GIF, adjust the volume, convert between MP4 and WebM, generate a waveform visualization. All running on your own device, so your voice memos, home videos, and work-in-progress clips never leave. Supported video formats include MP4, WebM, MOV, and AVI; audio covers MP3, WAV, AAC, OGG, and FLAC. Speed depends on your device: a few seconds on a laptop, a bit longer on a phone, especially for longer clips. The only hard limit is your browser's memory, which handles most things under 500MB without trouble. Because nothing uploads, there is no waiting in a queue, no rate limit, and no chance your draft lands on someone else's server. Drop the original back in to try a different trim; the working copy never replaces what is on your disk.
The tools support MP4, WebM, MOV, AVI for video, and MP3, WAV, OGG, AAC, FLAC for audio. Format support depends on your browser's media capabilities.
No server limit — processing happens on your device. Large files (over 500MB) may be slow depending on your device's processing power and available memory.
Yes. The audio extraction tool separates the audio track from any supported video format and lets you download it as MP3, WAV, or OGG.
