How do I resize an image without losing quality?

PixelShift uses high-quality interpolation algorithms to resize images. For the best results, avoid upscaling images too much (e.g., 2x is fine, 10x will look blurry).

Can I maintain the aspect ratio?

Yes! Aspect ratio lock is enabled by default. Enter either width or height, and the other dimension will be calculated automatically.
