How to reduce video file size online
Need help?
Read the FAQ
Choose a file from your computer or phone — Android, iPhone, Mac or Windows. It opens straight in your browser and is never sent to a server.
Pick Basic, Strong or Superb. The expected size is shown before you start, and you can remove the audio track if you don't need it.
Play the compressed video to check it, then download it. Not small enough? Try a stronger level on the same file.
Frequently Asked Questions
Choose Basic or Superb. Both keep the original resolution (up to 1080p) and lower the bitrate carefully, so most people can't see a difference on a phone or laptop screen. Strong saves the most space but softens the picture.
MP4, MOV, WEBM, MKV, AVI, M4V, 3GP, WMV, FLV, MPEG and most other common formats. The compressed file is always an H.264 MP4, which plays on every phone, browser and social network.
Most email services limit attachments to about 20–25 MB. Upload your video, look at the expected size of each level and pick the one below your limit — usually Strong for anything longer than a minute or two.
Yes. As soon as the file is opened, each level shows its expected size and how much smaller it will be. The final size usually lands within a few percent of that estimate.
No. There is no sign-up, no watermark and no daily limit.
You need a connection to open the page and to download the compressor the first time (about 30 MB). After that, the compression itself runs entirely on your device and does not use the internet.
Yes, it works in mobile browsers on Android and iPhone. Phones are slower than computers, so short clips work best there — keep the tab open while it runs.
No. Compression permanently discards some detail to save space, and it can't be added back. Keep your original file if you might need full quality later.
