Trim Video on iPhone

Don't want to download yet another app just to trim a video? JustTrimVideo works directly in Safari on your iPhone. No app store, no storage space used, no account needed. Just open the site and trim.

Why Not Use the Photos App?

The Photos app can trim videos, but it saves a new copy (doubling storage use) and re-encodes the video (quality loss). For quick trims you want to share immediately, a browser-based tool is faster and doesn't eat into your iPhone storage.

File Size Limits on iPhone

iPhones have less RAM than computers, so very large files (500MB+) may be slow or fail to process. For large 4K videos, consider using a Mac or PC. For typical phone videos (under 200MB), iPhone works great.
