Real browser tool
Reduce video file size while keeping visual quality practical
This is a working compression tool, not an AI generation form. It reads your local video, re-encodes it in the browser, and lets you download the compressed result.
Resolution and quality presets
Choose Original, 1080p, 720p, 480p, or 360p, then select High Quality, Medium Quality, or High Compression.
Free WebM download
The compressed result is exported as WebM, which works well for web sharing, previews, and smaller browser-friendly files.

Workflow
How to compress a video online
Use the original resolution when you want minimal visible quality loss, or choose a lower resolution for a smaller file.
1
Upload a video file from your device.
2
Choose Original resolution for near-lossless compression, or select a smaller resolution to reduce file size.
3
Pick a compression quality preset based on your file-size goal.
4
Click Compress Video and download the WebM result after browser processing finishes.
Limits
What this free compressor does not do
Clear limits help avoid fake claims. Browser compression is useful, but it is not the same as a professional server-side transcoding pipeline.
This is not a full professional transcoder and does not export MP4 yet.
Browser support varies; modern Chrome-based browsers usually work best.
Very long or high-resolution files can be slow because processing happens on your device.
Near-lossless means visually similar for many videos, not mathematically lossless compression.
Audio preservation depends on browser MediaRecorder support.
FAQ
Video compressor FAQ
Practical answers about browser-based compression, audio, resolution, output size, WebM export, and local processing.
Will the compressed video keep 1080p resolution?
Choose Original if you want to keep the source resolution. A 1080p video stays 1080p, but it is still re-encoded, so it is not mathematically lossless.
Can the compressed file ever become larger?
Yes. If the source video is already heavily compressed or has a very low bitrate, re-encoding may not reduce the size. Try Medium Quality or a lower resolution if file size matters more.
Does this tool keep audio?
It tries to keep the source audio track and records it into the WebM output when the browser supports audio capture. If audio cannot be captured, the result will show an audio notice.
Why does the download use WebM instead of MP4?
The current tool uses browser MediaRecorder, which can export WebM locally without a server-side transcoder. MP4 export usually requires heavier encoding support.
Is the video uploaded to ImagineClip?
No. The file is read and processed in your browser. The compressor does not upload the video during this workflow.
Which quality option should I choose?
Use High Quality for previews where visual detail matters, Medium Quality for sharing and web use, and High Compression when smaller file size is more important than detail.
What kind of videos work best?
Short clips under 100MB work best. Long videos, 4K files, or files with unusual codecs can be slower because all processing happens on your device.
