How it works

The engine sizes the image first, then searches for a suitable compression result.
Check all constraints
Download is enabled only after every requested value passes validation.
Common questions

What is the safest resize method?
Crop to fill keeps the requested ratio without stretching. Review the preview to ensure important content remains visible.
