What this tool does

01

Resize a video locally to 1920, 1280, 854, 640, or a custom even width. Height is calculated to preserve the source aspect ratio.

02

Choose a width that matches the delivery surface, encode, then inspect text sharpness and aspect ratio.

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

Create a 720p-width copy

Scale a large capture to 1280 pixels wide before web delivery.

Boundaries

What to check before relying on the result

  • Upscaling does not add source detail.
  • The output is re-encoded and can change color or compression characteristics.

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.
