Frequently Asked Questions

How does the Image Upscaler increase resolution without blurriness?
It employs intelligent bicubic/Lanczos interpolation and super-resolution edge preservation filters in canvas memory to upscale low-resolution images 2x or 4x while sharpening details.
Is it suitable for pixel art and digital illustrations?
Yes. It includes dedicated nearest-neighbor scaling modes for pixel art and vector-like graphics to keep crisp pixel boundaries without unwanted blur.
Is my source photo uploaded to an external server?
No. Upscaling executes entirely client-side using browser canvas rendering. Your sensitive or personal photos remain private on your computer.
