Frequently asked questions

What should I check before using the output?

Thumbnail availability and resolution vary. Respect copyright; cross-origin restrictions may require opening an image to save it.

What if a file or action is unsupported?

Check the input format and any visible error, try a smaller test case, and confirm the browser supports the required feature. Do not treat an empty output as a successful result.
