Frequently Asked Questions
How does image upscaling work?
The tool enlarges your image to 2x or 4x its original dimensions using high-quality browser interpolation, followed by a sharpening pass to enhance edges and details. This produces cleaner results than simple stretching.
What is the difference between 2x and 4x?
2x doubles both width and height (4x total pixels), while 4x quadruples them (16x total pixels). A 500x500 image becomes 1000x1000 at 2x or 2000x2000 at 4x. Higher scales produce larger files.
Can this replace AI upscaling?
Browser-based upscaling with sharpening is good for moderate enlargements. For the best quality on heavily pixelated or very small images, AI-powered super-resolution models produce significantly better results.
