Browser-based

What this tool does

01

Apply a visible pixel rotation and re-encode the video, rather than only changing a player-dependent rotation metadata flag.

02

Inspect current rotation, choose the pixel transform, encode, and test in more than one player.

03

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.

Representative tasks

Where this tool earns its place

Fix a sideways phone clip

Rotate pixels clockwise so players that ignore orientation metadata still display correctly.

Boundaries

What to check before relying on the result

  • Re-encoding is lossy and can change color or compression characteristics.
  • Existing rotation metadata may already affect displayed dimensions; inspect with Media Info first.

How to use

01

02Review the detected media facts and task-specific controls.
03Start the local job, watch progress, or cancel to terminate the worker.
04Play or inspect the downloaded result before replacing the source.

Tips & Tricks

  1. 01
    Start with a short representative file

    Confirm codec and browser support before committing device time to a long source.

  2. 02
    Keep the source

    Every output is a new file. Retain the original until you have completed a full playback check.

FAQ

02
Is 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.
