84.2 MBTurn a short 4K source into a shareable video
4K recordings contain far more pixels than many social posts, messages, and ordinary web players display. A short 4K source may therefore be a good candidate for a smaller delivery copy. Upload an MP4, MOV, or WebM source that is under 100 MB and three minutes. The compressor creates an MP4 at up to 1080p, so this page is for compressing footage recorded in 4K, not preserving a 4K output.
Keep your original recording if you may need the full resolution for future editing or large-screen display. Use the compressed version when smaller downloads and easier uploads matter more. A downscaled video can still look clear on a phone or in a typical web player, but small details can change. Preview faces, text, and fast movement before you share the result.
How to use the compressor
Check your 4K source
Choose a clip within the 100 MB and three-minute limits. Longer camera recordings should be trimmed or prepared in an editor before uploading. Keep the original 4K file separately.
Select a compression level
Start with Balanced for a general sharing copy. Choose Better quality if fine details matter, or Smaller file size when the transfer limit is more important. No level guarantees a particular file size.
Inspect the downloaded MP4
Watch the result at the size your audience will use. Pay attention to motion, text, and areas with fine texture. The output is limited to 1080p even when the input is 4K.
What changes when 4K footage is compressed?
Reducing a 4K recording to a maximum of 1080p removes pixels, and encoding reduces data further. This can be a useful tradeoff for a short clip that will be watched on a phone or embedded at modest dimensions. It is less suitable if viewers must zoom in on tiny labels or if the file is intended for a 4K master. A result that looks good at normal viewing size may still show less detail than the original when enlarged.
The source matters as much as the preset. Grain, rapid movement, and busy scenes are harder to compress cleanly than a steady, simple shot. If the result looks soft, try Better quality or shorten the clip before compression. If you need to retain true 4K resolution, use a workflow that explicitly supports 4K output. The main Video Compressor page explains the general upload and download process.
Frequently asked questions
Can I upload a 4K video?
Yes, if it is an MP4, MOV, or WebM within the 100 MB and three-minute input limits.
Will the compressed file stay in 4K?
No. This tool limits output to 1080p, so keep the original if you need a 4K master.
Which setting is best for 4K footage?
Balanced is a useful starting point. Try Better quality if important details look too soft in the preview.
Can I compress a long 4K recording here?
Only if the source is within the stated duration and size limits. Trim or prepare longer footage first.
Will compression always make my 4K file smaller?
The result depends on the source and chosen level. Check the downloaded file before relying on a particular reduction.
