AI Image Upscaler (2×)
AIExécuté sur Votre AppareilEnlarge photos 2× with a real neural super-resolution network (Swin2SR) that runs in your browser — no upload, no watermark, no credits.
This tool runs Swin2SR (~22 MB, downloaded once and cached) in your browser — a real super-resolution network that reconstructs edges and texture as it doubles the resolution. The image never leaves your device, and there are no watermarks, signups, or credits.
Honest limits: input larger than 640px on its long edge is downscaled first (so the output is up to 1280px), and ×2 neural detail is realistic reconstruction, not magic — it cannot recover what a truly blurry source never captured.

AI Image Upscaler — Real Neural 2× Super-Resolution, In Your Browser
Most "free AI upscalers" meter you to three images a day, stamp a watermark on the result, or quietly upload your photos to a GPU farm. This one runs Swin2SR — a real super-resolution network — inside your browser: the ~22 MB model downloads once (then works offline), the upscale happens on your device, and the full-resolution PNG is yours with no watermark and no account.
How it works: 1) Drop an image. 2) The neural network reconstructs it at double resolution — recovering edges and texture that plain stretching smears away. 3) Compare the before/after and download the upscaled PNG.
Being honest about limits: this is the classical ×2 model, so the output is 2× the input, and inputs larger than 640px are downscaled first to keep processing reasonable (final output up to ~1280px). And like every upscaler, it reconstructs plausible detail — it cannot recover detail a genuinely blurry source never captured.
