Trim Large Video Files Online
Most online video trimmers choke on large files. They have 500MB limits, crash on 1GB videos, or take forever to upload. JustTrimVideo handles large files effortlessly because nothing ever uploads - your video is processed locally on your device.
No File Size Limits
The only limit is your device's available memory. Desktop computers can typically handle videos up to 2-4GB. Even mobile devices can process files up to 500MB-1GB depending on the phone. The tool shows your device's specific limit when you load it.
How to Trim Large Videos
- 1 Select your large video
Click "Choose File" and select your video. It loads directly into browser memory - no upload wait.
- 2 Set your trim points
Use I and O keys or enter times manually. Works the same whether it's 100MB or 2GB.
- 3 Download instantly
Click trim and download. A 10-second clip from a 2-hour file takes the same time as from a 2-minute file.
Why Other Tools Fail with Large Files
Upload-based tools
Uploading a 2GB file takes 10-30 minutes on a good connection. Then you wait for processing. Then download. JustTrimVideo: zero upload time.
Arbitrary file limits
Most "free" tools cap at 500MB or 1GB, then demand payment. Our limit is your device's RAM, typically 2-4GB on desktops.
Server timeouts
Cloud tools often timeout on large files. Local processing never times out - your computer does the work.

Tips for Large Files
- Use a desktop computer - More RAM means larger files. Phones work but have lower limits.
- Close other browser tabs - Free up memory for the video processing.
- Use Chrome or Edge - They typically handle large files better than other browsers.
- Check your device limit - The tool displays your specific limit when loaded.
