Compress a 4K Video
To compress a 4K video, upload it below, choose a quality level, and download a dramatically smaller file — no desktop software, no command line. Modern phones and cameras shoot 4K at bitrates that produce hundreds of megabytes per minute, and browser-based compression cuts that down fast.
The catch with 4K is that the files are enormous long before they are useful: a two-minute iPhone 4K clip can outweigh an entire photo library backup. Unless the footage is headed for professional editing, most destinations — chats, drives, websites — do not benefit from that much data.
How it works
- 1
Upload your 4K footage
Drop in clips from your iPhone, Android, mirrorless or drone — anything up to 500 MB per file. HEVC and H.264 sources are both handled.
- 2
Pick your quality level
High keeps the footage looking premium while shedding serious weight. Medium and Low push the size down further for sharing and archiving.
- 3
Download the lighter file
Save the compressed video and compare — 4K sources typically shrink by a large factor because their original bitrates are so generous.
Why use Video-Matic
Biggest wins on 4K sources
High-bitrate camera files have the most fat to trim, so 4K clips see some of the largest size reductions of any input.
No heavyweight software
Skip installing an editor or wrestling with encoder settings — the browser handles a job that usually demands desktop tools.
500 MB per upload
Generous enough for several minutes of 4K straight off the camera; longer projects can be split and compressed in parts.
Footage stays private
Processing runs on EU servers in Paris and every file is deleted automatically within 24 hours of upload.
Frequently asked questions
Will my video still be 4K after compression?›
Yes — compression reduces the bitrate, not the frame dimensions, so the output keeps its 4K resolution. If you would rather trade resolution for size, run the clip through the resize tool at 1080p first; a downscaled and compressed file is far smaller than either step alone.
Why are my 4K phone videos so huge?›
Phones record 4K at high bitrates to preserve detail for later editing, often producing several hundred megabytes per minute at 60 fps. That headroom is wasted when the video is just going to be watched. Re-encoding at a sensible bitrate keeps the picture looking nearly identical while cutting the size drastically.
Which quality level should I choose for 4K footage?›
High is the safe default: 4K sources carry so much extra bitrate that High alone usually delivers a big reduction with little visible change. Choose Medium for sharing in chats and Low only when size matters far more than fine detail, since 4K fine textures are where low bitrates show first.
How many credits does compressing 4K cost?›
The same as any video: 1 credit per compression, regardless of resolution. A new account includes 3 free credits, and additional one-time credit packs are on the pricing page. There is no subscription, and files over 500 MB just need to be split before uploading.
