Frequently Asked Questions

Will resizing up (enlarging) work well?

Resizing down (making smaller) maintains quality. Resizing up (enlarging) introduces blur and pixelation — you're asking the browser to create pixels that don't exist. Start with the largest source image available.

What's the largest image I can resize?

The tool can handle images up to several thousand pixels in each dimension, browser memory permitting. Very large images (50+ megapixels) may slow down processing.
