关于此 视频压缩器 工具
The video compressor makes a video file smaller so it fits email attachments, chat apps and upload forms. It re-encodes the video as an efficient H.264 MP4 and can also lower the resolution, which is the biggest way to save space. Pick a level, optionally set a maximum resolution, and download the smaller file.

常见问题
How much smaller will my video get?
It depends on the original. Phone recordings and screen captures often shrink by half or more. Lowering the maximum resolution, for example from 1080p to 720p, saves the most.
Which compression level should I choose?
Balanced suits most videos. Choose Strong for the smallest file when some loss of detail is fine, and Light when quality matters more than size.
Will the video quality drop?
Compression always trades some detail for size. At the balanced level the difference is hard to see on a phone or laptop screen.
最大文件大小是多少?
Uploads up to 512 MB are supported. Longer videos take longer to process, so keep the browser tab open until the download appears.
Is the video compressor free and private?
Yes. It is free with no account and no watermark, and uploaded videos are stored only temporarily under random names before automatic cleanup.
