Details

How this should help in practice

These sections explain the job in plain language and set expectations for what the tool should do well.

Why this needs a dedicated page

People asking about transparency usually want a clear yes-or-no plus useful alpha evidence, not a general edit tool with another checkbox hidden inside it.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Will a JPG ever report transparency?

No. JPG does not support an alpha channel, so the checker will report that the source format has no alpha support.

Does this upload the image to a server?

No. The alpha analysis and preview happen locally in the browser.
