FAQ

Are images uploaded to a server?

No. Images are imported, converted, and exported on your device. Android may back up app settings through the system backup service when backup is enabled; images and temporary conversion files are excluded.

Is Photos access required?

On iPhone, add-only Photos access is requested only when saving to Photos. On Android, the system photo or file picker provides access to selected images; Android 8 and 9 may request write access when saving to the photo library.

What happens to animated GIF or WebP files?

The first frame is converted as a still image. Animation is not preserved.

Are there additional charges after purchase?

No. The app is a one-time purchase with no in-app purchases or subscriptions.
