Frequently Asked Questions
What's the difference between 2x and 4x?
2x doubles the image dimensions (4x the pixels), while 4x quadruples dimensions (16x the pixels). 2x generally produces better quality.
Will upscaling improve image quality?
Upscaling increases resolution and applies sharpening, but can't add detail that wasn't in the original. Start with the highest quality source image.
What's the maximum input size?
Free users can upscale images up to 512px on the longest side. Pro users can upscale up to 2048px images.
