Compress a large video file
Shrink a 1 GB, 2 GB or bigger recording without uploading it anywhere. Your computer does the work, so there's no upload wait and no file-size paywall.
Why big files work here
Most free online compressors have to receive your whole file before they can start, and cap free uploads to keep their server bills down. SqueezeVideos never receives the file. In Chrome, Edge and recent Safari, the WebCodecs encoder built into the browser reads the video in pieces and writes the smaller version as it goes, often with the graphics chip doing the heavy lifting.
What to expect
| Device | Comfortable file size | Tip |
|---|---|---|
| Desktop or laptop (Chrome, Edge) | Several GB | Close other heavy tabs; plug in a laptop |
| Mac (Safari) | Several GB | Chrome is a good second try if Safari stops |
| Phone or tablet | Up to a few hundred MB | Trim first; browsers give a tab limited memory |
| FFmpeg fallback (no WebCodecs) | About 1–2 GB | The whole file is loaded into memory |
Four ways to make a big file much smaller
- Drop 4K to 1080p4K has four times the pixels of 1080p. On most screens the difference is hard to see, and the bitrate needed falls sharply.
- 60 fps to 30 fpsUnless it's sport or gaming, halving the frame rate saves a lot of bits with little visible change.
- Trim the dead airLong recordings often have minutes at the start and end nobody needs.
- Use a % target"% of original" at 30–50% is a good first try when there's no fixed limit.
Need the numbers first? The bitrate and file size calculator shows how long a video fits in a given size. Exact sizes: 500 MB, 200 MB, 100 MB. Platform caps are on the upload limits page.
Questions people ask
How do I compress a 2 GB video for free?
Open this page on a computer in Chrome or Edge, drop the file in and choose a target such as 500 MB, or "% of original". The browser's WebCodecs encoder reads the file in chunks, so a 2 GB recording does not have to fit in memory all at once. Nothing is uploaded, so there is no upload wait and no paywall for big files.
Is there a file size limit?
We don't set one. The practical limit is your device: computers handle several gigabytes, phones are happiest under a few hundred megabytes. If your browser falls back to FFmpeg (WebAssembly), the whole file has to be loaded into memory, which in practice limits it to roughly 1–2 GB.
How long does compressing a big video take?
Roughly as long as the video plays, or faster, on a recent computer with hardware encoding; several times longer on older machines or with the FFmpeg fallback. Trimming first and choosing 1080p or 720p speeds it up a lot.
What target size should I pick for a large video?
Pick the destination's limit: 1 GB for Slack, 2 GB for WhatsApp and Telegram documents, or a percentage such as 30–50% of the original for archiving. A 4K phone recording usually looks almost the same at 1080p and a fraction of the size.
Why not use an online compressor that uploads?
Uploading 2 GB on a typical home connection can take longer than compressing it locally, and many upload-based tools cap free files at 1 GB or less. Local compression also keeps private footage on your device.
