Why use this tool?

Authentic Detail Preservation

Unlike generative AI tools that hallucinate random faces, fake textures, or distorted letters, our resampling preserves true photographic accuracy.

Stepped Multi-Pass Interpolation

Gradual scaling increments minimize aliasing and jagged pixelation for silky smooth gradients.

100% Client-Side Speed

GPU-accelerated in your browser. No upload queues, no wait times, and no token costs.

Frequently asked questions

Why choose Resampling over Generative AI Upscaling?

Generative AI creates fake textures, alters facial features, and can invent details that never existed in the original photo. Our mathematical resampling accurately preserves authentic shapes, logos, fine text, and forensic evidence without hallucination.

Can I upscale screenshots and logos?

Absolutely! Combined with our Edge Sharpness Boost slider, logos and screenshots enlarge cleanly with crisp lines.
