Question: Is there an app that can upscale images quickly and efficiently using my device's GPU?

If you need an app that can upscale images on your device with a fast and efficient use of your device's GPU, Let's Enhance is a top contender. This AI-based tool can upscale and improve blurry or low-resolution images to high resolution, up to 4K and beyond. It also has batch processing, background removal and HDR filters, so it's good for creative professionals, e-commerce and real estate.

Another contender is Remini, which uses AI to improve low-quality photos and videos. It can upscale photos and videos up to 2x without any loss of quality and fix common photo problems like blur and focus. Remini runs on mobile devices and through a simple API, so it's good for social media, heritage preservation, printing services and e-commerce.

SuperImage is another contender if you want a locally installed app that uses your device's GPU for the heavy lifting. It uses AI and a neural network to improve image quality and runs on Android and Windows. Because it doesn't need to upload your data to the internet, it keeps your data private.
