Video & Audio
Tools for dashcam, phone and lecture videos, recordings and music. No sign-up, no install, and your files are never sent to a server – everything runs in your browser.
Video and audio tools that don't upload your files
Most online video editors make you upload hundreds of megabytes first. These tools download the video engine (ffmpeg) to your browser and work on your device only: no upload wait, and family videos, dashcam footage and meeting recordings never leave your computer or phone. The video engine is about 32 MB the first time and comes from your browser cache after that.
Videos and MP3s that share a format are processed without re-encoding, so quality is unchanged and it takes seconds. Re-encoding runs as software in the browser and is slow, so use a computer for long videos.
Which tool do I need?
- To turn dashcam or phone clips into one video, use Merge Videos.
- To split a long video or keep just one part, use Split & Trim Video.
- To join split recordings or audiobook chapters into one file, use Merge MP3.
- To convert SRT, VTT or SMI subtitles or fix their timing, use the Subtitle Converter.
Limits
- Results are built in your device's memory: up to 1–2 GB on a computer, a few hundred MB on a phone.
- DRM-protected video and audio can't be processed, and AVI results can't be previewed in the browser.
