YouTube Video Compressor

Reduce a large video before uploading to YouTube while keeping text, motion and audio clear.

When to use the YouTube compressor

Useful when bandwidth is limited or a large tutorial, presentation, recording or draft takes too long to upload.

Duration and quality

For YouTube, visual quality usually matters more than reaching the smallest file. Longer videos need a larger size budget.

Recommended resolution

Keep 1080p when detail matters; use 720p only when upload size or speed is the priority

Recommended output settings

Use MP4/H.264 with AAC and avoid an unnecessarily tiny target. Preview the result at full screen before uploading.

If compression or upload fails

Retry with H.264, lower the resolution or target size, trim unnecessary footage, close other tabs and start again from the original. Recheck the platform's current upload screen before sending.

All videos are processed locally in your browser. Refreshing or closing the page clears the video and result.
