    I am looking for clarification on two issues. The FAQ includes this passage:
    It should say “Serving existing converted image” the first time, but “Serving existing converted image” on subsequent requests.

    What is the difference between “Serving existing converted image” and “Serving existing converted image“?

    I have purchased an api key from EWWW but it appears to be optimizing various images and I cannot find any setting either with the plugin or with EWWW to set it to only convert jpg and png to webp. I purchased the .99c api and EWWW is keeping track of every optimization, counting how many are left (after which I expect to be charged again).

    Thanks, this passage is clearly wrong.
    It should have said:

    There should be a “X-WebP-Convert-Status” header. It should say “Serving freshly converted image” the first time, but “Serving existing converted image” on subsequent requests

    But actually, I need to rewrite this because I did some changes.
    Instead of summing up what was done in one status header, multiple status headers are added, showing the process.

    The conversion library (webp-convert) emits:

    First visit:
    X-WebP-Convert-Log: Converting (there were no file at destination)
    X-WebP-Convert-Log: Serving converted file

    Subsequent visits:
    X-WebP-Convert-Log: Serving converted file

    When a .htaccess rule redirects directly to an existing webp, the following header is output:

    x-webp-express: Redirected directly to existing webp

    As to ewww: As long as you dont install the ewww plugin, there is no way WebP Express will use it to “regular optimization”. It will only use EWWW to convert to webp. I have added no setting, because WebP Express only deals with converting and serving webps instead of png/jpeg – it does not deal with optimizing jpegs or optimiing pngs.

    Thanks very much for the clarification. Could you tell me where I would find the X-webp-express-Convert-Log?

    It is in the FAQ:
    – Open the page in Google Chrome
    – Right-click the page and choose “Inspect”
    – Click the “Network” tab
    – Reload the page
    – Find a jpeg or png image in the list. In the “type” column, it should say “webp”

    Note that you will not see this header if you enabled Alter HTML.
