About Video Compressor

The Video Compressor allows you to quickly shrink the file size of local video files directly inside your browser without uploading your media to any external servers. Featuring multiple compression quality presets (Low, Medium, High), target resolution downsampling (1080p, 720p, 480p, 360p), and framerate controls, the tool re-encodes video streams locally using browser MediaRecorder pipelines. You can review a live side-by-side comparison of your original vs compressed file size, check the percentage of storage saved, and preview the resulting video before downloading.

Frequently Asked Questions

Does this tool upload my video to a server to compress it?

No. The entire compression process takes place locally inside your browser using HTML5 Canvas and MediaRecorder APIs. Your video file never leaves your computer or phone.

How much can I reduce my video file size?

Depending on your original video bitrate and the preset selected (e.g. downscaling 1080p to 720p or 480p), you can typically reduce video file sizes by 40% to 80% with minimal perceived quality loss.

Will compressing my video degrade its audio track?

The tool preserves the synchronized audio track while re-encoding the video stream to ensure balanced overall size reduction.

Which formats are supported for compression?

You can compress any video container natively supported by your browser, including MP4, WebM, and MOV.
