How small can it get?

A 1080p phone clip taken down to 720p at medium quality typically lands between a fifth and a half of its original size. Footage that is already compact will barely move.

Can I hit an exact target size?

Not directly here. Pick a resolution, look at the size reported under the result, and drop one step further if you are still over. Two passes almost always land it.

Does it lose quality?

Yes, and any tool claiming otherwise is either not compressing or not telling you. The controls exist so you can choose where the loss goes: fewer pixels, fewer frames, or coarser detail.

Will it work on several files at once?

Yes. Add them all and the same settings run down the list, one after another, with progress shown per file.

About the Compress Video

A video that will not attach to an email, will not upload to a form, or eats a quarter of the space on a phone has one of two problems, and telling them apart saves a lot of wasted effort.

If the file is large because the picture is enormous — 4K footage of a whiteboard, a 1080p screen recording of some text — then resolution is the lever. Halving the height quarters the number of pixels, and no quality setting ever devised competes with removing three quarters of the data before compression begins. That is why the resolution control sits at the top of this page and defaults to 720p, which is more than enough for anything watched on a phone or embedded in a document.

If the file is large because a great deal is happening in it — a hand-held walk through a market, confetti, rain — then quality is the lever, and the honest news is that there is less room than people hope. Movement is genuinely expensive to store. Dropping the quality on busy footage buys size at a visible cost, and no tool avoids that trade by being clever.

The third control, frame rate, is the one people forget. A screen recording of somebody scrolling through a document does not need sixty frames a second; fifteen looks identical and stores a quarter as much. On real-world footage of moving people it is much less forgiving, which is why it is left alone by default.

One warning that saves disappointment: a file that has already been compressed hard — anything downloaded from a social platform — will not shrink much further without becoming visibly worse. The size it arrived at was somebody else's answer to this same question, and they had the original to work from.

How to use it

1Add one video or a batch of them.
2Choose a resolution to shrink to. This does more than everything else on the page combined.
3Lower the frame rate if the footage is a screen recording or a slideshow.
4Set the quality, run it, and compare the before-and-after figures under the result.
