How to trim MP4 online

Have a clip in MP4 that you want to split into multiple parts? Need to quickly trim an MP4 online? Try Fastreel by Movavi then!

Fastreel by Movavi is an online platform that lets you create videos without having to install additional software. It works great as an online MP4 trimmer. The fast processing, intuitive interface, and swift preview let you cut out unwanted parts of the video in just a few clicks.

Here’s how to trim MP4 with Fastreel by Movavi:

Step 1. Visit the website

Click the button below to go to the Fastreel site.

Step 2. Add the video file

Click the Add Your File button or drag-and-drop the video into the box on the page. Note that the file you want to upload should be under 500 MB. If you’re working with a bigger file, it’s better for you to get the desktop alternative – Movavi Video Editor.

Step 3. Trim the video

There are two ways to cut out unwanted parts from your video with this MP4 trimmer.

To get rid of the beginning or the ending part of your video, drag one of the two yellow edges of the recording on the Timeline to the desired point. If you trim the beginning of the video, don’t forget to move the final clip to the beginning of the Timeline.

If you want to delete a part in the middle of the clip, you’ll have to use the splitting tool. Drag the red marker to the point the unwanted fragment starts, then click Split. After that, find the point where the cutout should end and click the same icon again. Finally, select the unwanted piece and click the Trash can icon under it.

Step 4. Save the result

Click Export in the top-right corner of the window. You can choose to export the video with or without the watermark and in various sizes. When you’re done with the settings, the platform will start processing the trimmed video. When it’s done, the result will both appear on the web page and be sent to your email.
