AI Upscale: Enlarge Images

Really quick upscale and surprisingly great results

First time trying to upscale pictures and this app made it so easy. Nice interface and great results.

The workflow stumbles, and the final results are not the quality expected. These may be honest bugs. AI Upscale makes use of the Photos library to source and export images. This is tedious and limiting: photographers looking for a serious tool are most likely not using the Photo app and library for their workflow, and using it only for this purpose introduces additional hurdles. The solution is to introduce AIU import and export images with the Files explorer for Pro users. Enhanced images, as seen in the AI Upscale enhanced preview, appear to have great results: the enhanced image is sharp and has great colour depth at higher alleged dimensions. But when the enhanced image is saved back to the Photos Gallery, the result appears to be heavily compressed, with smaller dimensions than the enhanced image, and with a reduced bitrate resulting in heavy color banding. The preview in AIU looks great—so what’s happening when it’s saved? The AIU preview is limiting, offering a sliver of detail of the enhanced image at full size, or a ‘fit to screen’ view. ‘Tap to do X’ options do not respond. Neither view is as useful as a full size, loupe view of the enhanced image for verifying details are being enhanced appropriately. In addition to the ‘save to gallery’ option there is a ‘Share Image’ button, but this fails with the message “Failed to share image”. Dev: I can offer you screenshots. Source images tested in 8-bit and 16-bit Jpeg and Tiff on ipadOS 18.x and 26.x All results saved back to Photos are 8 bit, heavily compressed. Version 7.0: images saved to photos look better, with no banding, but still are not the dimensions of the enhanced image. The other issues remain in v7.
