What’s New Version 7.2.12
Fixed the issue that the image picker is not scrollable while selecting images.
Description
This app can scale and/or denoise images using various advanced on-device AI algorithms. Note that this app is not affiliated with the original waifu2x project.
Privacy is one of the top priorities of this app. Your files will never leave your device to be processed. Additionally, we don't collect any personal information because there are no ADs even if you only use free models. Therefore, if you encounter any problems, please send us a feedback email or create a GitHub issue so that we can work together to fix them.
Try additional models and custom models on your own images for free before you purchase!
Highlight features:
1. Unlimited number of imported images.
2. Supports both SRCNN and CUnet models from the original waifu2x project.
3. Supports Real-ESRGAN models for both illustrations and photos.
4. Supports Real-CUGAN models for anime illustrations. Also supports customizable intensity.
5. Supports Anime4K models for anime videos.
6. Supports custom Core ML models. Import any model to process images for your specific needs.
7. Custom scale modes. You have options to scale images up to 128x, 1.5x, fixed size and more.
8. Supports multiple ways of importing images: the album, files, folders, drag and drop, other apps, Shortcuts.
9. Supports images with alpha channel.
10. Multiple output formats: PNG, JPEG, HEIF, WebP.
11. Multiple processing backends. You can choose between highest quality or highest speed.
12. Write output images directly to an external path (including network drives like SMB).
13. End-to-end support for 16-bit color and color spaces. Color accuracy will not be compromised after processing.
14. Highly optimized RAM usage. You can easily produce images that don't even fit inside your device RAM.
15. Supports deleting or replacing original images if they come from the album.
16. Supports downscaling images before processing, which is useful while processing some photos.
