Frequently Asked Questions

Does resizing an image lock the aspect ratio by default?

Yes. By default, changing the width automatically calculates the proportional height so your image never looks stretched or squashed. You can toggle the lock off at any time.

What happens if I upscale a small image to larger pixel dimensions?

The canvas uses high-quality interpolation to scale the pixels smoothly, though upscaling raster images cannot invent new detail beyond the original source.
