Trim Video
Cut a video to a precise start and end time and create a new encoded clip.
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
Trim a local video with start and end timestamps. The compatibility path re-encodes the result so cuts are not restricted to source keyframes.
Inspect the source duration, set a valid start before end, process, and check both boundary frames.
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
Keep 00:12 through 00:42 from a longer product recording.
What to check before relying on the result
- Timestamp precision is bounded by source timing and encoder behavior.
- Re-encoding changes the encoded bitstream and invalidates file-level signatures.
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.
