Common questions

How do I compress a video?

Open the app, choose a video from your library, pick a quality level (or, with the unlock, an exact target size) and a resolution, then tap Compress. You can preview the result for free; saving it to Photos or sharing it needs the one-time unlock.

The compressed file is bigger than I expected.

A video can only shrink so far before quality suffers. Try a lower resolution (720p or 480p), the Smaller quality level, or removing audio. With the unlock you can set an exact target size. The size shown before compressing is an estimate; the real result appears after.

Why can I only compress one video at a time?

Batch compression (up to 10 videos at once) is part of the one-time unlock. The free version compresses one video at a time at up to 720p.

Why are 1080p and Original locked?

Full 1080p and original resolution are part of the unlock. Free compression goes up to 720p.

Does it work offline?

Yes. Everything runs on your device with no internet connection required.

How do I save to my photo library?

After you unlock, tap Save to Photos on the result screen and allow add-only photo access when prompted. If you declined earlier, turn it back on in iOS Settings, Privacy & Security, Photos, Video Compressor.

"Can't read this video" or "This file has no video track".

The selected file could not be opened as a video, or it contains only audio. If the clip is stored in iCloud Photos, make sure you are online so it can be fetched, then pick it again.

Purchases

Premium is a single one-time purchase, not a subscription. The price is shown in the app before you buy.

Bought it already, or moved to a new device? Open the upgrade screen from Settings in the app and tap Restore Purchases, signed in with the same Apple ID.

If you subscribed weekly or annually in an earlier version, the subscription keeps working. Manage or cancel it in your Apple ID Account Settings: how to cancel a subscription.
