Getting started

Image Compressor makes a photo fit the size an upload asks for: a maximum, sometimes a minimum and a pixel size, measured on the real file. Open the app and choose one or more photos from your library, or a file. Pick one of the size options, or type your own numbers in Custom. Tap Compress. When it finishes, the result screen shows the file's measured size against your range, and you can save it to Photos or Files, share it, or copy it.

Compressed copies stay in the app for the window you chose in Settings, 7 days by default, so you can come back and save or share one later.

Common questions

Will the file really be inside my range? Yes. The size shown on the result screen is the byte count of the file the app produced, measured on disk. Forms rarely say whether a KB is 1,000 or 1,024 bytes, so the app aims for a file that is inside the range either way: at most 1,000 bytes for every KB in the maximum, and at least 1,024 bytes for every KB in the minimum. A form that says 40 to 120 KB, for example, gets a file at or below 120,000 bytes and at or above 40,960. If those two readings cannot both hold, the app reads KB as 1,000 bytes for both and says so on the result.

What is the filler a result can mention? When the smallest file the app can make is below your minimum, it can add a small amount of filler to bring the file up to the minimum. The picture is unchanged, only the file is a little larger. The app never does this on its own: it offers it and pads only if you accept. Filler is only added to JPEG files.

Why does it suggest Save to Files when there is a minimum? Saving to Photos can re-encode the copy, which can push it below your minimum. Save to Files hands over the exact file the app measured, so use that when a form sets a minimum. For an upload form, choose the file from Files.

Does it change my original photo? No. The app writes a new file and leaves the original untouched. Location and camera details are removed from the copy.

Where did the compressed photo go? It is in the app until the window you chose in Settings passes, or you delete it. Saving to Photos adds a copy to your photo library; the first time you do that, iOS asks for add-only permission.

Why did saving to Photos fail? Usually the Photos permission was turned off. Open iOS Settings, find Image Compressor, and allow Photos access.

Why was my photo refused? A few things, each with its own message. RAW photos are not supported, so export a JPEG or HEIC from Photos first. Animated images, such as GIF or APNG, are not supported. A photo can also have too few pixels for the size you chose, or the app may not be able to get under the maximum at that pixel size; the refusal then shows the smallest file it can make and offers a smaller size. The refusal screen names the reason and offers one way out, and no free photo is used.

How many photos are free? Three. A photo counts only when it is delivered inside its range. Photos that fail, land outside the range, or that you stop do not count, and compressing the same source again does not count twice. The count is kept on your device, not with an account.

How do I get the unlock back after reinstalling? Open Settings in the app and tap Restore Purchases. Sign in with the same Apple Account you bought it with.

How do I get a refund? Purchases are made through Apple, so refunds are too. Use Apple's report-a-problem service at reportaproblem.apple.com.

Is there a subscription? No. Three photos are free, then one purchase unlocks the app for good.
