FAQ

Is Resizia free?

Yes. Resizia is completely free, with no in-app purchases, subscriptions or ads.

Are my images uploaded?

No. Everything is processed on your device, and the app collects no data. See the Privacy Policy.

How do I resize a photo?

Tap “Photos” (or “Files”) and choose an image. Pick a mode – “Dimensions”, “File size” or “Both” – set the width / height (“W” / “H”) or a “Target” size in KB or MB, then tap “Start” and “Save to Photos” or “Share”.

Which formats are supported?

Input: JPG, PNG, HEIC, WebP and other formats the system can decode. Output: JPEG, PNG or HEIC. PNG is not offered in File size / Both modes, because a lossless format can’t target a file size.

Why wasn’t the target size reached?

For very small targets the app lowers quality and then automatically reduces the dimensions. If the target still can’t be met, it shows the closest result with a note.

Width and height got smaller after choosing a crop ratio?

A ratio crop (1:1, 4:3, 3:4, 16:9, 9:16, 3:2, 2:3) keeps the largest area with that ratio, so the width or height is smaller than the original. The output is still the highest resolution for that ratio.

Smart crop didn’t find a face?

Small, side-on or poorly lit faces may not be detected. The app then looks for the main subject, and otherwise crops from the centre. Tap “Adjust crop” to drag the frame yourself; a manual position always wins over the automatic one.

What are “Common sizes” and “My modes”?

“Common sizes” are built-in sizes such as profile photo 1:1, square, portrait 3:4 and 4:5, vertical 9:16, article cover, banner 3:1 and video thumbnail 16:9 (common reference values you can change as needed). You can also save your own sizes, with an optional file-size limit. “My modes” saves your whole setup under a name (up to 20, stored only on your device) so you can apply it again with one tap.

How does batch processing work?

Tap “Batch (up to 9 photos)”, choose up to 9 photos, set “Max width” / “Max height” (or a target size or preset), tap “Start batch”, then “Save all” or “Share all”. With a crop ratio selected, each photo’s crop can be adjusted individually.

What if I share more than 9 photos?

Up to 9 photos are processed at a time. On iPhone and iPad, Resizia appears in the share sheet when 1–9 images are selected; select 9 or fewer.

Do my output images include the location?

Not by default. “Remove photo info (location, etc.)” is on by default, so outputs contain no GPS location, device model or capture time. This info is kept only if you turn the switch off.

Saving fails / “Photos access is turned off”?

Go to Settings › Privacy & Security › Photos › Resizia and choose “Add Photos Only” or “Full Access”.

Can’t find Resizia in the share sheet?

In the Photos app, tap Share, then tap “More” at the end of the app row and turn Resizia on. Choose Resizia, tap “Done” in the “Add to Resizia” panel and open Resizia – the shared photos load automatically.

How do I change the language or appearance?

Tap the gear icon at the top right. You can choose from 35 interface languages or “System default”, switch between Light and Dark, or turn on Night mode (dark automatically from 19:00 to 07:00).

Text too small?

Turn on “Elder mode” in Settings for larger text and buttons.

Where is the privacy policy in the app?

Open Settings › About › Privacy and tap “Privacy Policy” to read the full policy in the app. The same text is on the Privacy Policy page.

Restore the default settings?

Open Settings and tap “Restore default settings”.
