Three targets, no settings
Web 1080p, web 720p, light 480p. Each one fixes a resolution, a frame rate and a bit rate. Nothing else to decide.
iPhone app
Ch'ti Press
A video shot on an iPhone is far heavier than a web page needs. Put it on a diet, on the phone itself.
Free. No account, no upload, no analytics.
What it does
Everything on the phone
Compression runs on the device hardware encoder. Your videos are never uploaded anywhere, so there is nothing to wait for and nothing to trust.
Several clips at once
Queue up to twenty videos. Each one shows its size before and after, and how much came off.
Ready to upload
H.264 in an MP4, with the index at the front of the file so a browser can start playing before the download finishes.
How it works
-
Pick a target
720p covers most sites. 1080p for a full-width hero video, 480p when the file has to be tiny.
-
Choose your videos
The system picker opens. Ch'ti Press only ever sees the clips you hand it.
-
Save or share
Put the result back in your library, drop it into Files, or send it straight on. The original is untouched.
Privacy policy
Ch'ti Press collects nothing, transmits nothing and shares nothing. The app has no server, no account and no third-party SDK: no analytics, no crash reporting, no advertising.
Videos are read only when you pick them yourself in the system photo picker, and they are compressed on the device. A working copy lives in the app's private storage while the job runs, and goes away when you clear the list or delete the app.
The app asks for permission to add videos to your photo library, and only to add: it cannot read your library. That permission can be revoked at any time in Settings.
The only setting kept between launches is the target you last used. Deleting the app deletes everything.

FAQ
- Does it change my original video?
- No. The original stays in your library exactly as it was. The compressed copy is a new file.
- Why is my 1080p video still 1080p on the 1080p target?
- Ch'ti Press never enlarges a video. A clip already smaller than the target keeps its resolution and only loses weight through the frame rate and the bit rate.
- Which iPhones does it run on?
- Any iPhone running iOS 17 or later.
- Is anything uploaded?
- No. There is no network code in the app at all.
