How to Trim a Video Online
Drop your video, drag the start and end handles on the preview, then click trim. Choose lossless copy for an instant result on MP4 files, or re-encode for maximum compatibility with any format. Trimming is the step between a raw recording and a shareable clip: cut the dead air, the fumbled starts and the extra footage, and what is left looks deliberate. The tool gives you two engines. Lossless copy mode re-uses the original encoded video and finishes in seconds, but cut points land on the nearest keyframe, usually within half a second to two seconds of where you clicked. Re-encode mode rebuilds the file so every cut is exact to the frame, at the cost of a short processing wait. Both modes work entirely in your browser, and the original file on your device never changes.
- 1. Upload your videoDrop a video up to 500 MB. Every format your browser plays is accepted.
- 2. Drag the cut handlesSet the start and end points on the preview. Use the frame buttons for single-frame precision.
- 3. Pick lossless or re-encodeLossless is instant and keeps original quality on MP4, but cuts snap to the nearest keyframe. Re-encode is frame-accurate and works with any format.
- 4. Download the trimmed clipClick trim and save the result. The rest of the video is untouched, and nothing is uploaded to any server.
- Tip: the lossless mode keeps original quality but trims to the nearest keyframe (about 0.5–2 s). Need exact cuts? Use re-encode.
- The cut handles snap to keyframes in lossless mode. If the cut lands a second off, switch to re-encode for the exact frame.
- Trimming the middle out is the quick way to delete a bad segment without splitting the video into pieces.
- Use the keyboard arrows to step one frame at a time. The first and last frames are where fades and titles live.

FAQ
Frequently asked questions
Is Video Trimmer really free?
Yes — completely free, with no hidden fees, no premium tier and no signup required. The tool runs entirely in your browser.
Do I need to install anything to use Video Trimmer?
No. Video Trimmer works directly in your browser. There is no software to install, no app to download and no plugin required.
Is my video uploaded to a server when I use Video Trimmer?
Never. All processing happens locally on your device. Your file never leaves your computer, which is why there is no upload wait and no privacy risk.
Which video formats does Video Trimmer support?
It accepts MP4, WebM, MOV and MKV — anything your browser can decode. Output is MP4 by default, playable on any device.
What happens to my file after processing?
Nothing is stored anywhere. Once you close the tab, everything is gone. We have no server, no storage and no access to your files.
Will my video have a watermark?
No — every download is 100% watermark-free. EditVideo never adds logos, branding or watermarks to your files.
Can I trim a video without losing quality?
Trimming cuts frames out — the frames you keep are untouched. Our tool then re-encodes them, which is where a small, invisible quality step happens. For the absolute best result, trim to a keyframe boundary; in practice, our quality-first encode looks identical to the source on any screen.
What's the difference between trimming and cropping?
Trimming shortens the timeline — you remove a part from the start or end (or cut out a middle section). Cropping changes the frame — you keep the full duration but only a rectangular region of the picture. Use trim to remove unwanted moments, crop to fix framing. Our toolset has both, separate pages.
Can I trim a video without losing quality?
Yes. Lossless mode keeps the original encoding, so quality stays byte for byte identical on MP4 files. The trade-off is that cuts land on the nearest keyframe instead of the exact frame you clicked.
What is the difference between trimming and cropping?
Trimming removes footage from the start, end or middle, so the video gets shorter in time. Cropping cuts the picture area, so the frame gets smaller in space but the duration stays the same.
Why do my cuts land a second away from where I clicked?
Lossless mode cuts at keyframes, which repeat every half second to two seconds in most videos. For exact cuts, pick re-encode mode and the cut lands on the frame you chose.
Which mode is faster?
Lossless is nearly instant because the existing video is copied, not rebuilt. Re-encode has to process every frame, so it takes longer and depends on your computer.
Can I cut out the middle of a video?
Yes. Set the start and end handles around the part to remove, and that segment is deleted. The parts before and after stay and join together.
What formats can I trim?
Anything your browser plays: MP4, WebM, MOV, MKV and more. Lossless copy is available for MP4, and every format works with re-encode.
Is there a file size limit?
Yes, videos up to 500 MB are accepted, which covers most phone and camera clips. Longer files process locally, so your hardware, not a server, sets the practical pace.
Is my video uploaded anywhere?
No. Trimming runs entirely in your browser. The file never leaves your device, so long recordings stay private even without an internet connection after the page loads.
Does trimming change my original file?
No. The trimmed clip downloads as a new file. The original video on your device stays exactly as it was.
Why does re-encode mode exist if lossless is faster?
Because the two modes solve different problems. Lossless is for speed and untouched quality. Re-encode is for frame-exact cuts, formats other than MP4, and fixing videos whose keyframes do not line up with your edit points.
