Pixelup is an AI photo upscaler that restores crisp detail, reduces noise, and fixes compression artifacts—right on your device. Open any low-resolution image, upscale it up to 4×, preview the result, and export in high resolution for social, print, or storefronts. The first sentence is punchy and clear, then a scannable feature list—exactly the pattern Apple recommends for product pages.
