Blurry photo? Low-resolution screenshot? AI upscaling sharpens and enlarges images 2x or 4x in your browser — free, private, and surprisingly effective.
Resizing an image up always meant blur — a 400×300 photo stretched to 1600×1200 looks like a smudge no matter which algorithm does the stretching. AI upscaling works differently: a neural network analyzes the image and reconstructs plausible detail — edges become crisp, textures regain structure, faces stop looking like watercolors. The result is not magic, but for most real-world images it is dramatically better than any traditional resize.
AI upscaling reconstructs detail; it cannot invent information that was never captured. A 200-pixel screenshot upscaled 4x will look smoother and sharper than any alternative, but it will not look like a native 4K photograph. The realistic sweet spot is 2x for photos and 4x for graphics, logos and text-heavy images — where the model can predict edges and shapes confidently.
Because the neural network runs on your device via ONNX Runtime Web, personal photos — including faces — are never uploaded to a server for processing. That makes AI upscaling safe for family photos and unreleased designs alike, and it is also why there are no resolution caps or paid tiers: the computation is on your machine, so there is nothing to meter.
Upscale first, then compress: enlarge with AI, then run the result through Image Compress or Image to WebP to keep the enhanced file lightweight for the web.
