Does resizing reduce image quality?

Downscaling generally preserves quality well. Upscaling beyond the original resolution may result in some softening or pixelation.

Can I resize without changing the aspect ratio?

Yes. Enable the aspect ratio lock to automatically calculate the proportional dimension when you set either width or height.

What is the maximum size I can resize to?

You can resize images up to 10000x10000 pixels. Larger dimensions may take longer to process.
