What is Online Video Editor?
An online video editor trims video duration in your browser. Input: a local video file (any browser-supported format) plus start and end times. Output: the trimmed clip.

▶FAQ6 questions
What is an online video editor?
A browser-based video trimming tool. Input: a local video file plus start/end times. Output: the trimmed clip. Preview and download supported — videos are never uploaded.
Which video formats are supported?
Any format the browser can play natively: MP4 (H.264), WebM, OGG, and more. MP4 is recommended for best compatibility.
Does trimming re-encode the video?
No. The front-end trim remuxes the clip via MediaRecorder without expensive re-encoding. Resolution and codec match the source.
How precise can the trim be?
Slider precision is 0.01 seconds — enough for most editing needs.
Is there a file size limit?
Limited by browser memory; keep videos under ~500MB. Very large files may slow the page.
Is my video uploaded to a server?
No. Everything happens locally in your browser. Your video never leaves your device.
