100% PRIVATE · CLIENT-SIDE

Upscale photos without uploading them.

Enlarge low-resolution images directly in browser memory using WebGPU or WebGL2 shader processing, with a safe Canvas fallback.

Photo upscaler

Your image stays on this device and is removed from memory when you leave or reset the page.

or click to choose a PNG, JPG, WebP, or AVIF image

Recommended maximum input: 25 megapixels

Private by design

No image upload endpoint is used. Processing happens locally inside your browser.

GPU accelerated

Uses WebGPU when available, then WebGL2, with a Canvas fallback for broader compatibility.

High-quality filters

Choose bilinear, bicubic, or sharper Lanczos-style reconstruction with optional edge enhancement.

Important disclosure

This tool performs mathematical image enlargement and sharpening. It does not know what is in the photo and cannot reliably restore detail that was never captured. Very large outputs may exceed your browser or GPU memory limits.
