An image upscaler built to enlarge, not just stretch
Every step of the upscaling pipeline is tuned to preserve edges and texture instead of smearing them across more pixels.
Progressive resampling
Large resolution jumps are split into smaller resampling steps, which keeps edges cleaner than a single blunt resize to 2x or 4x.
Edge-aware sharpening
A detail-reconstruction pass runs between each resampling step to bring back the crispness that plain image scaling normally softens away.
Nothing leaves your device
There's no image upload, no account, and no server round-trip — the entire upscaling pipeline runs locally in your browser.
