About the Compress Video tool
Phone videos are recorded at a very high quality, which makes the files huge. Compress Video saves your video again at a sensible size and quality, usually making it 50–90% smaller while it still looks good on a phone or laptop. Choose a resolution such as 720p, or enter a file size in MB and the tool works out the quality that fits — handy for email attachments, chat apps and upload forms with a size limit. The result is an MP4 that plays everywhere. Your browser does the work with your device's video hardware, so the video is never uploaded.

Frequently asked questions
How much smaller will my video get?
It depends on the video, but phone videos usually become 50–90% smaller with the recommended 720p setting. A stronger setting, such as 480p, makes the file even smaller.
Can I compress a video to a set size, like 25 MB?
Yes. Choose “Fit under a file size” and enter the size in MB, and the tool sets the quality so the video fits. A very long video may need a bigger size, or you can remove the sound to save space.
Will the video look worse?
Some detail is always lost when a video gets smaller, but at 720p most videos still look sharp on phones and laptops. Choose the light setting (1080p) if quality matters most.
Is my video uploaded anywhere?
No. The video is compressed inside your browser on your own device. Nothing is sent to a server, so private videos stay private.
