Convert on our server?

If you continue, the file is uploaded over an encrypted connection and converted on our server. You can keep using the site meanwhile. The original is deleted as soon as it is converted; the result is kept for 6 hours so you can download it, and you can delete it at any time. Files are never shared or used for anything else.

  3. 3 Play the selected section to check that the cut is right.
  4. 4 Click Trim video, wait for local processing, then download the finished clip.

About this tool

Use the Video Trimmer to keep a specific section of a longer clip, remove an unwanted beginning or ending, or prepare a shorter video to share. Choose a video from your device, play it in the editor, and mark the section with the timeline handles or the start and end fields. The preview and trim points stay in your browser.

The first time you trim, the browser loads the video engine (about 31 MB) on demand; it is not downloaded when the page opens. Trimming then runs on your device and the output keeps the source container format. Some uncommon codecs or large files may not work locally. In that case, the tool asks before uploading the video for temporary server processing.

Use the player to find a moment, set the start or end to the current playback time, and play the selected section before exporting. Cuts are made at video frame boundaries, so the final point can land on the nearest frame. Download the finished clip from the result panel.

Frequently asked questions

Does the Video Trimmer upload my video?

Trimming runs in your browser after the video engine loads on demand. Your video stays on your device when local processing works. If the format or file cannot be handled locally, the tool asks for permission before sending it for temporary server processing.

Which video formats can I trim?

The file picker lists the supported video formats. The result keeps the original container, such as MP4, MOV, AVI or WebM. Some codecs and containers need server processing if the local engine cannot encode them.

How do I set the exact start and end?

Drag the timeline handles, type a time such as 1:30 or 0:45.5, or play the video and use the buttons to set a point at the current time. The cut is aligned to a video frame.

Why does the video engine take a while to load?

The editor downloads its video engine only when you first trim a clip. The download is about 31 MB and is normally cached by your browser, so it should not be needed again unless the cache is cleared.

Can I preview a video that does not play in my browser?

Yes. Choose Prepare a preview MP4. The tool temporarily uploads the video for conversion after asking permission; you can then set trim points using the preview. The trim still uses your original file.

Will trimming reduce video quality?

The selected section is re-encoded so the cut can be placed accurately. This can slightly change image or sound quality. The output keeps the original container format, but its internal codecs may differ.

Which video formats can be processed locally?

Local processing is attempted for MP4, MOV, MKV, AVI, WebM and other supported containers. Success also depends on the codecs inside the file, its size and your device. If local processing cannot handle the conversion, we ask before using the server.
