Help & frequently asked questions

Everything happens on your iPhone. No upload, no account, no waiting — the app works fully in airplane mode.

Getting started

  1. Tap Choose Photos and pick the images you want to shrink.
  2. Set the quality and pick an output format.
  3. Tap Compress. Each photo shows its size before and after.
  4. Use Share to send the result anywhere, or Save to put it back in Photos.

Questions

Which format should I pick?

JPEG is the safest choice — every app and website accepts it. HEIC reaches roughly half the file size at the same visible quality and is what your iPhone uses for its own photos, but some older software cannot open it. PNG is lossless, so the quality slider does not apply; use it only when you need exact pixels.

The file got bigger instead of smaller. Why?

This is normal for some images. JPEG is designed for photographs; it handles smooth gradients well and fine noise or sharp-edged graphics badly. A screenshot or a simple graphic saved as PNG is often already smaller than any JPEG version of it. The app shows the change in orange when a file grows, so you can see it and pick a different format or a lower quality.

Is the original photo changed?

No. The original stays untouched in your library. Compressed results are new files that you explicitly share or save.

What is removed from my photos?

Camera and location metadata is stripped from the output. That makes the file smaller and stops your location travelling with a photo you share.

How many photos can I do at once?

The free version compresses 3 photos at a time. There is no limit on how often you use it. Unlocking removes the batch limit and enables HEIC output.

I paid but the app still shows the limit

Open Settings in the app and tap Restore Purchase. Make sure you are signed in with the same Apple Account you bought with. The unlock is a one-time purchase, not a subscription — there is nothing to renew.

Can I get a refund?

Refunds are handled by Apple, not by us. Visit reportaproblem.apple.com and sign in with your Apple Account.

Does it work without internet?

Yes, completely. The app makes no network requests at all.
