Frequently asked questions

Will resizing keep my image sharp?

Downscaling generally keeps images looking sharp. Upscaling beyond the original size can look soft because no new detail is created. Dimensions are capped at 8000px.

What does lock aspect ratio do?

It keeps width and height proportional so your image never looks stretched or squished. Change one dimension and the other follows automatically. Uncheck it to set width and height independently.

Which output format should I choose?

PNG is best for graphics and screenshots, JPEG gives the smallest files for photos, and WebP is the smallest of all on modern websites.
