How it works

How to compress a video, free, in three steps.

1
Drop in your video
MP4, MOV or WebM, of any size: a phone video, a screen recording, a 4K camera file. It opens in your browser; nothing is uploaded.
2
Choose a size or a quality
Type the size it has to fit under, like 20 MB for Discord, or choose Small, Balanced or High quality. You see the resolution and the expected size before you start.
3
Download the smaller MP4
An H.264 MP4 that plays everywhere. If it comes out over your size, it's made again smaller, automatically, until it fits.

Why this one

Free, with nothing held back, and nothing uploaded.

Hits the size you need

Ask for under 20 MB and you get under 20 MB: the bitrate is worked out from the length, and the file is checked and redone if the encoder overshoots.

Looks as good as it can

Rather than starving a 4K picture of bits, the resolution steps down to what the size can carry cleanly, and 60 fps drops to 30 when bits are short.

No upload, no waiting

Compressing on your own device skips the slowest part of every online compressor: uploading a big file and downloading it again. The browser's hardware encoder does the work.

Free, with no limits

No watermark, no sign-up, no file size cap of ours and no daily limit. Compress as many videos as you like.

Your file is opened and processed by your own browser. It is never sent to a server, so it stays private, and there’s no upload to wait for.

How video compression works

A video's file size is its bitrate times its length. Phones and cameras record at very high bitrates, 50 megabits a second for 4K iPhone video, far more than a video shown on a phone or in a chat needs, which is why compressing makes such a difference.

This compressor works out the bitrate that fits your size, picks the largest resolution that bitrate can carry cleanly and encodes an H.264 MP4 with your browser's hardware encoder. Choose a quality instead and it compresses as far as it can while still looking right.

Questions

The video compressor: your questions, answered.

How do I compress a video without losing quality?

Choose High quality: the video keeps its resolution and gets enough bitrate to look the same, and the file still shrinks, often to a third of its size, because phones record at far higher bitrates than they need. No compression is truly lossless, but at High it's very hard to see.

Is there a free video compressor with no file size limit?

Yes. Because this one runs in your browser rather than on a server, there's no upload and no size cap of ours: multi-gigabyte files work. The only limit is your device's speed.

How much can a video be compressed?

Phone and camera videos are recorded at high bitrates, so a 5–10× reduction often looks nearly the same. Below about 2 megabits a second, 1080p video starts to lose detail; the tool steps the resolution down to keep the picture clean, and warns you when a size is too small to look good.

What format is the compressed video?

An MP4 with H.264 video and AAC audio: the most widely playable video format there is. It plays on phones, in browsers, in Discord, WhatsApp and email clients, and in every editor.

Is this video compressor really free?

Yes. There's no price, no trial, no account and no limit on how many files you do. The video compressor runs on your own device, in your browser, so it costs us nothing to run and we don't charge for it.

Does it add a watermark?

No. The file you download has no watermark, no logo and no intro or outro added. It's your file, changed only in the way you asked.

Is my video uploaded anywhere?

No. The file is opened and processed by your browser, on your device, and never sent to a server: not to us, not to anyone. You can check: watch the Network tab of your browser's developer tools while it works, and you'll see the file is never sent anywhere.

How big a file can it handle?

There's no file size limit of ours. Files of several gigabytes work, because the file is read from your disk as it's needed rather than loaded all at once. What sets the pace is your device: a long 4K video takes longer on an older laptop than on a new one.

Which browsers does it work in?

Current versions of Chrome, Edge and Safari, and Firefox on a computer: any browser with the WebCodecs API for encoding video and sound. Some files, like iPhone HEVC video, need Chrome, Edge or Safari to decode. A computer is much faster than a phone for long videos.
