Crop Video
Crop a video to a rectangular pixel region and re-encode the visible area.
Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint. TOOLGRID measures tool usage, not the content you enter.

What this tool does
Crop video with explicit width, height, X, and Y values. The workspace validates even output dimensions for H.264 compatibility.
Inspect source dimensions, set an in-bounds even rectangle, encode, and check every edge of the result.
Processing starts only after you choose files and press the action button. The media engine is not preloaded on the homepage or ordinary tool pages.
Where this tool earns its place
Crop the content region while preserving the original timing and audio.
What to check before relying on the result
- Crop coordinates are source pixels before rotation metadata is applied.
- Invalid or out-of-bounds rectangles fail instead of being guessed.
Open a nearby browser tool when you need to validate, convert, or reuse the result.
How to use

Tips & Tricks
- 01Start with a short representative file
Confirm codec and browser support before committing device time to a long source.
- 02Keep the source
Every output is a new file. Retain the original until you have completed a full playback check.
FAQ
02Is my media uploaded to TOOLGRID?
No. The selected files are written into an in-browser worker file system. The self-hosted encoder assets are downloaded separately, but TOOLGRID does not receive the selected media for processing.
Why can a local media job be slow?
The compatibility encoder runs single-threaded in WebAssembly and is limited by device CPU, available memory, source duration, resolution, codecs, and browser behavior.
What should I verify in the result?
Check playback, duration, seeking, video and audio synchronization, expected tracks, visual quality, and actual file size in the browser or player used by your audience.
