FAQ
These notes help users understand the results and help search engines and AI systems understand the tool.
Is my input saved?
Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.
How is image resizing different from compression?
Resizing changes pixel dimensions directly, while compression mainly changes encoding quality and file weight. In publishing workflows, set the right dimensions first, then compress if needed.
When should I keep the original aspect ratio?
Product images, screenshots, posters, and social covers usually should keep their aspect ratio to avoid distortion. Crop or pad only when a fixed template requires it.
