Frequently Asked Questions
Does resizing reduce image quality?▾
Resizing to smaller dimensions removes pixel data but we use high-quality resampling. Enlarging small images will reduce quality as the software needs to "guess" extra pixels.
How do I keep the aspect ratio?▾
Tick the "Maintain aspect ratio" box. When you change one dimension, the other updates automatically to keep the image from stretching.
What's the maximum size I can resize to?▾
Up to 10,000 pixels on either dimension. Keep in mind that extremely large images will consume more memory in your browser.
