Professional Video Compressor

Compress video locally with measured output size, resolution, quality and audio controls instead of a blind one-click preset.

Why this tool is different

Compress video locally with measured output size, resolution, quality and audio controls instead of a blind one-click preset. Controls expose the decisions that materially affect the result instead of hiding them behind a one-click preset.

Requirements and recommendations

How to use Video Compressor

  • Choose a readable video and inspect its real duration, dimensions, codecs and bitrate metadata.
  • Choose a quality level, optional maximum resolution and audio bitrate instead of accepting a hidden preset.
  • Review the measured before/after byte size and keep the original when the result is not worthwhile.
How OpenFileTools processes it

Local processing, explicit choices.

Media is read from the selected File/Blob in this browser. The media engine is lazy-loaded only on these routes; OpenFileTools does not upload the source to its servers.

Frequently asked

Questions, answered.

Is my media uploaded?

No. Source bytes remain on this device and are read directly by the browser. OpenFileTools does not receive the file.

Why can a recognized file still fail?

A container and the codecs inside it are separate. Browser decoder and encoder support varies by operating system and browser, so the tool checks the actual track rather than promising universal conversion.

Does processing change my original?

No. A separate result is created for preview or download; the selected source file is not modified.
