FAQ
Frequently asked questions
How do I resize without distortion?
Enable Preserve aspect ratio or use Fit inside. Avoid Stretch to fill when source and target proportions differ.
Can I enlarge an image?
Yes, up to the safety limits, but enlargement interpolates pixels and cannot restore missing detail.
