Video
Smaller file, same video
Every other free compressor wants you to upload your footage first. This one does not. It does the work on your own machine, and the file never leaves it.
Compress a video
Runs on your device, nothing uploaded
Your video is read off your disk, drawn to a canvas at the size you picked, and re-encoded by your own browser. No server is involved at any point, which is also why there is no file size limit and no queue. Re-encoding is lossy, so start from your original export rather than from a copy that has already been squeezed.
Three steps
How it works
Drop a file in
Nothing uploads, so there is no wait and no size cap beyond what your own browser can hold.
Pick a size and a quality
Resolution does most of the shrinking. Quality is the fine tuning on top of it.
Save it
Your browser encodes it and hands it straight back. If it comes out bigger than what you started with, we say so.
What it is for
Why this one is worth having
Nothing gets uploaded
The file is read off your disk, drawn into a canvas and re-encoded in the tab. No server anywhere in that, which is also why there is no queue.
It admits when it failed
Re-encoding a file that is already small makes it bigger. Most tools hand it back anyway. This one tells you to keep what you had.
It is not fast
It runs at playback speed, so a 30-second clip takes about 30 seconds. That is the trade for not paying for a server.
FAQ
Video size compressor, asked and answered
Does my video get uploaded?
No. It is read off your disk, re-encoded by your browser, and handed straight back. There is no request to a server anywhere in that, no account, and no copy of your footage except the one already on your machine.
Why is there no file size limit?
Because it costs us nothing. Other tools cap you at 100MB because every megabyte is their bandwidth bill. None of this touches our servers, so the only limit is what your own browser can hold at once.
How much smaller will my video get?
Usually somewhere between half and a fifth, depending on what you started with. Straight out of a phone or an editor, a lot. Something that has already been through Instagram, barely, and sometimes not at all.
Will it look worse?
A bit, yes. It is a re-encode. On the balanced setting you will not spot it in a feed. Start from your original export where you can, because the quality loss stacks every time you do this.
Do I get an MP4?
In Chrome, Edge and Safari, yes. Firefox can only make WebM, and the page tells you which one you are getting. Every major platform takes both.
Why is it slower than other compressors?
It runs at playback speed, so a minute of video takes about a minute. The fast ones are fast because they run on servers somebody is paying for, and the price of that is handing them your footage.
