How do I crop an MP4 video for free?
To crop an MP4, simply pick your video file inside the online tool. Drag the handles to adjust the frame borders to your liking, or choose a preset layout size. The tool processes everything directly on your computer, meaning your file is never uploaded and the results are ready instantly.
Can I crop an MP4 to a specific aspect ratio?
Yes, you can easily change your video to popular dimensions like square 1:1, vertical 9:16, or widescreen 16:9. The tool allows you to manually adjust the cropping box or select standard presets to make sure your video fits your favorite social media platforms perfectly.
Does cropping an MP4 reduce quality?
No, your video quality stays sharp. Because the tool processes your changes locally on your own computer, it preserves the resolution and details of your original footage. Your final video exports quickly without getting blurry or pixelated.
Is there a size limit when cropping MP4?
No, there are no file size limits or upload caps. Since your video file stays safe on your device and does not get uploaded to a cloud server, you can change the dimensions of large files without facing long waiting times or browser crashes.
Can I edit my MP4 after cropping?
Yes, you can keep working on your file. After you finish framing your shot, just click to continue into the main Flixier editor. This lets you combine multiple videos, cut out unwanted mistakes, add automatic subtitles, or insert music tracks without leaving your browser.
What file formats are supported?
Flixier supports MP4, MOV, AVI, WMV, M4A, MPEG, GIF, and many other formats. You can also paste a YouTube or cloud link directly into Flixier to import videos instantly.
Can I crop multiple MP4 videos at once?

What size can I crop videos to?
