Who is it for?
- Useful when you want to choose compression settings yourself and keep the video on your device instead of using an upload site.
- Useful when you want to see a preview and the estimated file size before downloading the result.

Getting started
- Open compress.addy.ie and drag in a video or browse for the file.
- Optionally open Settings to change the compression method, codec, frame rate, resolution scaling or audio bitrate.
- Click Compress Video, watch the preview and progress, then download the compressed video and check it.
Decision points
- If keeping files off a server matters, the README says all processing happens locally in the browser; still review it against your own privacy needs.
- If you need batch jobs or a watch folder, the README does not describe them; compare a desktop compressor.
Limits
- The live page showed only the title Video Compress when reviewed, so feature details come from the GitHub README and the current interface may differ.
- The README gives no file-size or duration limit; large videos may be limited by your browser and device, so test a short clip first.
- Account, pricing and support terms are not described in the reviewed sources.
Frequently asked questions
Is my video uploaded to a server?
The README says compression runs client-side with FFmpeg.wasm and that no server upload is required. This review did not run the app.
Which settings can I change?
The README lists compression method, codec selection, frame rate, resolution scaling and audio bitrate, plus a real-time preview and file-size estimate.
Why is the tool called Video Compress on its page?
The live page title reads Video Compress, while the GitHub repository calls it Browser Video Compressor; the README links compress.addy.ie as the demo and the repository owner is Addy Osmani.
