How to Trim MP4 Video Online

  1. Upload Your MP4 File: Click "+ Add Files" to select an MP4 file from your computer, Google Drive, or Dropbox.
  2. Choose Settings: Select compression method — quality preset (Highest to Lowest), target file size percentage, specific file size in MB, constant/variable bitrate, or CRF quality level. Optionally change video codec, audio codec, or resolution (preset like 1080p/720p, percentage, or custom width×height).
  3. Download: Click "Trim" and download your trimmed MP4 file.

Why Trim MP4 Files?

Trimming removes unwanted portions from the beginning, end, or middle of a video:

Social Media Clips

Extract the best 15-60 seconds from longer videos for Instagram Reels (90s max), TikTok (10 min max), YouTube Shorts (60s max), or Twitter/X (2:20 max).

Remove Dead Air

Cut silence, countdowns, or "are we recording?" moments from the start of meeting recordings and presentations.

File Size Reduction

A 1-hour recording trimmed to the relevant 5 minutes is 92% smaller — no compression needed, just removing unused footage.

Lecture Segments

Extract specific topics from long educational recordings for focused study or sharing individual lessons.

Competitors like aconvert.com "directly cuts the selected part without decoding, encoding, or converting, so it runs very fast." floik.com allows "exact timestamps for precision editing." podcastle.ai positions it as "creating social media clips, removing unwanted footage, or customizing video length." XConvert offers trimming with optional re-encoding, codec selection, compression, and resolution control.

Trim vs Cut

"Trim" and "cut" are often used interchangeably. On XConvert, both set a start time and duration to extract a segment. See also Cut MP4.

Frequently Asked Questions

Does trimming reduce quality?

Without re-encoding, trimming copies the original stream — zero quality loss. If you change codec or compression settings, re-encoding occurs with minimal quality reduction at default settings.

Is it free?

Yes. Completely free with no watermarks, no sign-up required, and no file count limits.

Can I trim to exact timestamps?

Yes. Enter times in seconds or HH:MM:SS.sss format for millisecond precision.

Can I trim multiple videos at once?

Yes. Upload multiple MP4 files and trim them all with the same settings.

Does it work on mobile?

Yes. Works in any modern browser on all devices — no app installation required.
