Video Trimmer — Frequently Asked Questions
Everything you need to know about using Video Trimmer.
What video formats are supported?
MP4, WebM, MOV, MKV, AVI, and any format your browser can natively play. Output keeps your input format.
Will trimming reduce my video quality?
No. Trimming is a lossless operation — the existing video and audio streams are kept intact, just clipped at your chosen points.
How precise can I trim?
Timestamps to one decimal place (100 ms precision). For 30fps video, that is about 3-frame accuracy.
Is there a file size limit?
No imposed limit. Practical cap is your device memory — 1–2 GB videos work on desktop, smaller on mobile.
Do my videos get uploaded?
No. Trimming happens entirely in your browser. Your video never leaves your device.
