Good to know
No upload
The video is compressed by your browser, so there's no upload to wait for and nothing is sent to a server.
Aims for your size
In Target size mode the result is checked, and compressed again with a lower bitrate if it came out too big.
MP4 for any device
Saved as MP4 with H.264 video where your browser supports it, the format phones, WhatsApp and websites expect.
Smart resolution
Auto lowers the resolution when the size is too small for full quality, so the video stays watchable instead of blocky.
Frequently asked questions
Is my video uploaded?
No. Compression happens in your browser with its built-in video encoder. The video never leaves your device.
Will it always fit under the size I choose?
Almost always. The tool spreads the size over the video's length, checks the result and compresses again up to two more times if it's over. If a video is very long for the size, it tells you the smallest size that works, so you can pick a bigger one or trim the video first.
Why did my video get a lower resolution?
With Resolution on Auto, the tool lowers the resolution when the size limit leaves too few bits for every pixel. A sharp 480p video looks better than a blocky 1080p one. Pick a resolution yourself to override this.
How long does it take?
It depends on the video's length and your device. A one-minute clip usually takes well under a minute on a recent phone or computer, because the browser's video encoder often uses the device's hardware.
Which videos can I compress?
MP4, MOV (including iPhone videos), WebM and MKV. H.264 and VP9 videos open in every supported browser. H.265 (HEVC) videos need a device that can decode HEVC. If your browser can't read a file, the tool says so.
Does it change the frame rate?
Only above 30 frames per second: 60 fps videos are saved at 30 fps, which saves a lot of space and looks the same for most clips.
