Apologies for overlooking your review when you posted it. If this error still appears in version 1.4, can you share the URL of the page with the problem image(s), either here or on Github at https://github.com/jscher2000/Save-webP-as-extension/issues or by email at jscher2000@outlook.com.

Hmm, the canvas used for the format conversion should scale to the natural dimensions of the image, but it sounds like there is some enlargement factor that I missed with those. So I can test the problem site, could you email me at jscher2000@outlook.com or submit a new issue on https://github.com/jscher2000/Save-webP-as-extension/issues ? Thanks.

As a workaround until then, you can try the "IE11" button, which re-requests the image as an older browser to discourage sending modern formats. Depending on the site, that may work for you.

(Update: version 1.5.1 pops up a little panel with some more options when the script is denied permission to read the page. Previously that just caused silent failure.)

Hi morpheen, does the add-on entry show on the right-click context menu? If so, do the buttons display when you click the item? If so, do any of the buttons work or are they all nonresponsive?

Sorry, yes, I changed a default setting in the last update. The bar used to always pop up in the "stand-alone" viewer (when you Open Image in New Tab). Now it only pops up automatically for WebP and AVIF images. But you can change it back in the Settings/Options.

Under "Button Bar Options" in the "Auto-close and Auto-open" section, there is a checkbox for "image/webp and image/avif only" -- uncheck that box to make sure the bar opens for all images if you might want to save a JPEG or PNG in a different format.

Hi, if you click the "gear" button on the info bar, you can find that option in the "Auto-close and Auto-open" section -- check the box in the parentheses:

[x] Open bar automatically on stand-alone web images ([x] image/webp and image/avif only)

I thought that was the default. [update 3/27/2023: version 1.3.3 sets that as the default, but this is not retroactive to existing installations if you have customized any settings already]
