Compress video in your browser
Choose a size — 8 MB, 25 MB, or any number you type — and the video is re-encoded to fit it. Your file never leaves your device, so even a large clip starts straight away.
Most "file too large" messages come down to a single number: the limit of the app or inbox you are sending to. This compressor works backwards from that number. You choose the size, and the bitrate — and the frame size, if it has to — are worked out so the finished file lands just under it.
How to compress video online
Open your video
Drop the file onto the editor or choose it from your device. Nothing is uploaded, so even a large file opens immediately.
Pick a target size
Tap 8, 10, 25, 50 or 100 MB, or type any size into the box. The panel shows the estimated file size and frame size before you export.
Trim if it is long
Every second you cut leaves more of the size for what remains, so a shorter clip comes out noticeably sharper.
Export
The video is encoded at a constant bitrate worked out from your target and downloads as MP4 or WebM.
How the size target works
A video's size is its bitrate multiplied by its length. A 60-second clip at 25 MB has roughly 3.2 megabits per second to spend, minus a little for the sound. The compressor spends that on the picture, and if it is too little for the original resolution it lowers the frame size as well, because a smaller sharp picture looks better than a large blocky one. You see the estimate in the panel before you commit.
Shorter is the best compressor
Cutting the clip is the most effective way to raise quality at a fixed size. If a clip still looks soft at your target, trim the start and end, or set Max FPS to 24. For a talking-head clip or a screen recording, both changes are almost invisible and free up a lot of the budget.
Your video never leaves your device
Most online video editors upload your file to their servers before you can touch it. This one works differently: every edit and every export happens inside your browser, on your own hardware.
Compression is usually the last step before you send something to someone, which means the file is often personal: a family clip, a recording from work, footage you are sharing with one person rather than the internet.
Here it never leaves your device. Your browser decodes the video, re-encodes it at the size you chose and saves the result next to the original.
Compress video — questions and answers
How small can I make a video?
As small as you like, but quality falls with size. As a rough guide, a minute of 720p video looks good at 20 to 30 MB and is watchable at 10 MB. Below that, trim the clip or accept a smaller frame.
Will the file be exactly the size I picked?
It aims just under it. The video is encoded at a constant bitrate worked out from your target, with a margin for the sound and the file structure, so it normally lands a little below the number you chose.
Why did the frame size go down?
When the target leaves too few bits for the original resolution, the frame is scaled down until each pixel gets enough detail to look clean. The panel shows the new frame size before you export, and choosing a larger target keeps more of the resolution.
Does compressing change the format?
You choose. MP4 is the default and plays everywhere. WebM is available too, and the Convert tool can turn a short clip into a GIF instead.
Is there a file size limit?
There is no upload, so there is no upload limit. The largest video you can compress depends on your device’s memory; a computer handles long 4K files more comfortably than a phone.
Is my video uploaded to compress it?
No. Your browser re-encodes the file on your own device. Nothing is sent to a server, so there is no queue and no copy left anywhere.
Can I compress a video for email?
Yes. Most email services cap attachments at about 25 MB, so the 25 MB button fits the common limit. If your provider uses a different limit, type it into the size box.
