Trim Video
Trim Video is a free tool that cuts a video down to the part you want. Set the start and end by typing a time, using the current playback position or stepping one frame at a time, and you see the exact first and last frames before you save. It exports an H.264 MP4 with the original sound, and a fast mode cuts without re-encoding. It runs in your browser, so your video is never uploaded.

How to Trim a Video
Step by step
- Choose a video from your computer or phone.
- Set the start and end. Drag the sliders, type a time like 1:05.5, or pause the player and click "Use current time."
- Fine-tune with the frame buttons. The two pictures show the exact first and last frames that will be in your clip.
- Click Trim video.
- Play the result and download the MP4.
How do I trim a video to the exact frame?
Use the -1 frame and +1 frame buttons next to the start and end times. The pictures under the player are decoded straight from your file, so they show exactly the frames that will start and end your clip, not an approximate thumbnail. Leave the cut mode on Exact, which re-encodes the video so the cut lands on precisely those frames.
What is the difference between Exact and Fast mode?
Exact mode re-encodes the video so it starts on the exact frame you chose. Fast mode copies the original video data without re-encoding, so it's very quick and there's zero quality loss, but a video can only start on a keyframe, so the clip may begin up to a few seconds before your start time. Fast mode works for H.264 videos, which includes most MP4 files from phones and cameras.
Does trimming reduce quality?
Fast mode doesn't change the quality at all. Exact mode re-encodes at a bitrate matched to your original, so the difference is very hard to see. If you need the file smaller as well, run the trimmed clip through Compress Video.
Does it keep the sound?
Yes. AAC sound is copied over without re-encoding and cut to match the video. Other audio formats are converted. Uncheck "Keep the sound" for a silent clip.
Which browsers does it work in?
It works in current versions of Chrome, Edge and Safari 16.4 or newer, on computers, Android phones, iPhones and iPads. Firefox 130 or newer on a computer usually works too. The tool uses WebCodecs, the browser's built-in video encoder, which is often hardware accelerated. If your browser doesn't support it, the page tells you right away.
Is there a file size limit?
Up to 2 GB on a computer and 1 GB on a phone or tablet. The new file is put together in your browser's memory, so very large videos could crash the tab. Long videos just take longer. Speed depends on your device; computers and phones with hardware video encoding are often faster than real time.
Is my video uploaded?
No. Your video is read from your device, processed by your browser and saved back to your device. It never touches a server, which also means there's no upload to wait for. See our Privacy Policy.
