VidCompress / Large files
Multi-gigabyte recordings, exports, and 4K clips shrink to a fraction of their size. Set a target and VidCompress does the heavy lifting.
Or jump straight to a destination:
Large video files — long recordings, high-bitrate exports, 4K footage — are slow to upload, awkward to share, and quick to fill storage. The good news is that big files usually carry the most wasted bitrate, so they compress dramatically with little visible change.
Set a target and VidCompress shrinks the file as far as you need while keeping it sharp. Files under 300 MB compress locally in your browser; larger files use the fast cloud path.
Add the large file
Drop in your recording or export. MP4, MOV, WebM, MKV, AVI, and WMV are accepted.
Choose a target size
Set a custom target, or pick a preset for a known limit. Large files have lots of headroom to shrink.
Let it compress
VidCompress re-encodes efficiently, holding resolution high while cutting wasted bitrate.
Download the result
Get a far smaller MP4 that uploads, shares, and stores easily.
How much can a large video shrink?
Often 70–90% smaller, because big files usually carry far more bitrate than the picture needs. The exact amount depends on your target.
Is there a file size limit?
Files under 300 MB compress locally in your browser. Larger files are handled on the fast cloud path.
Will quality drop a lot?
Not at sensible targets. Large files have so much wasted bitrate that big reductions stay visually clean.
Do I need to install anything?
No. It runs in any modern browser.
Is it free?
Yes. The free plan compresses up to 300 MB locally with no signup or watermark.
