Compress a video

Tap Choose videos and pick one or more from the system picker. Klein makes a smaller copy on your iPhone. Your originals stay in Photos, untouched.

Set a size limit

Open Size limit and enter a target in MB — useful when something has to fit an email or upload cap. Klein aims for that budget; if a copy still lands over the limit, the app says so.

Trim before compressing

Tap Trim on a selected video and set the start and end, then tap Done. Only the trimmed range is compressed.

Where copies are saved

Copies stay inside Klein until you act on one. Open a copy and tap Save to Photos to put it in your library, or Share to send it somewhere else.

Fix Photos permission

Klein asks for add-only Photos access the first time you save, so it can write a copy without reading your library. If saving is refused, open iPhone Settings → Privacy & Security → Photos and allow access for Klein, then tap Save to Photos again.

If Klein says Photos didn't confirm the save, the earlier attempt may have succeeded; saving again can create a duplicate in Photos.

Delete a copy

Open the copy and tap Delete copy, or swipe it away in the list. The original in Photos stays, as does anything you already saved or shared. Removing the app deletes every copy it kept on your iPhone.
