Compress an iPhone video
Free, in your browser, nothing uploaded. Drop the file, press the button.
iPhones record at high bitrates — often 4K and 60 fps — so a short clip can be hundreds of megabytes. ShrinkClip re-encodes it to a compact MP4 that texts, emails and uploads without a fight, and it all happens on your device.
uses your device's built-in video encoder · nothing to install · no file ever leaves your browser
No upload queue
Compression runs on your own CPU. A 500 MB recording never crawls up your connection to someone's server — there's nothing to upload, wait on, or trust.
No command line to learn
The same H.264 encoding professionals tune by hand — with the bitrate math and resolution worked out for you. Pick a size, press the button.
Private by default
Your video is processed in browser memory and discarded when you close the tab. We never see a frame of it — only anonymous size and preset stats.
Questions people actually ask
Do I need to convert HEVC first?
No. Drop the clip straight from your phone or Photos export; ShrinkClip decodes it and re-encodes to H.264 MP4, which plays on Android and Windows too.
Will it downscale my 4K video?
Only when the target size makes 4K pointless — a small file can't feed that many pixels, so stepping down to 1080p or 720p actually looks sharper at the chosen size.
