FAQ
What can I solve with this page?
You can simplify a ratio, solve a missing width or height, and compare contain versus cover behavior inside a target box.
When should I use contain versus cover?
Use contain when the full image must stay visible inside the box. Use cover when the box must be fully filled even if some cropping is required.
Does this page resize files?
No. It calculates dimensions and crop expectations only. Use an image resizer when you need actual file output.
Does the share URL include image files?
No. The share URL stores only the numeric dimensions and ratio inputs.
