About the Trim Video
This video trimmer keeps just the part you want. Play the video, set the start and end with the Use current time buttons or by typing times like 1:15, and choose how to cut. Exact mode re-encodes the clip so it starts and ends precisely where you chose. Fast mode copies the original video without re-encoding, which is almost instant and keeps the original quality, but the start moves back to the nearest keyframe. The trimmed video keeps its original format and is made on your device, never uploaded.

Picking precise points
Pause the video, then use the arrow keys or drag the timeline to find the exact frame. Press Use current time; the time is filled in with hundredths of a second. On phones, drag slowly and pause before pressing the button.
Why fast trimming moves the start
Videos store a full picture only every few seconds, called a keyframe, and the frames between them only record changes. Without re-encoding, a clip can only begin on a keyframe, so fast mode starts a little early to make sure nothing you wanted is missing.
How it works without uploading
Your browser has a built-in video engine (WebCodecs) that phones and computers use to play and record video. This tool uses it through Mediabunny, an open-source media library, to read your file, change it and write a new one, all inside the page. Speed depends on your device: a recent phone or laptop handles a few minutes of HD video comfortably, while long 4K files take longer.
Common uses
Cutting a long recording down to the important moment, removing the fumble at the start of a phone video, making a short clip for social media, or trimming a screen recording before sharing it.
- Social clips: 15–60 seconds
- Video replies: cut to the answer
- Lectures and meetings: keep only the key part
File formats
The trimmed video keeps the format it came in: MP4 stays MP4, MOV stays MOV, WebM stays WebM and MKV stays MKV. Other formats are saved as MP4. To change format at the same time, trim first and then use the Video Converter.
Phone and computer
The player controls are large enough for touch screens. Long videos take longer in Exact mode; Fast mode is quick on any device. To make the clip smaller use Video Compressor, and Video to GIF turns it into a short loop.

Frequently asked questions
What is the difference between Exact and Fast?
Exact re-encodes the clip so it begins at the very frame you chose. Fast copies the original data, so it is nearly instant and lossless, but can only start at a keyframe, often up to a few seconds earlier.
How do I type times?
Use seconds (75), minutes and seconds (1:15) or hours too (1:02:30). Decimals like 12.5 work.
Can I cut a section out of the middle?
This tool keeps one section. To remove a middle part, trim twice to make two clips.
Does trimming reduce quality?
Fast mode doesn't change quality at all. Exact mode re-encodes at high quality, which is visually very close to the original.
Which browsers work best?
Chrome and Edge on computers and Android support the most video formats. Safari 16.4+ and recent Firefox work too, but some codecs, such as HEVC in Firefox, may not be supported there.
Is my video uploaded?
No. It is processed on your own device with your browser's built-in video engine, so private videos never leave your phone or computer.
