FAQ
- Can I compare different image sizes: yes, the tool normalizes them before computing.
- How threshold works: lower values are more sensitive, higher values mark only obvious changes.
- Why difference ratio looks high: compression, resampling, or slight shifts can increase it.
- Are images uploaded: no, loading and comparison run locally in your browser.
