Convert a mailer

Outlook Classic cannot render WebP, so those images come out blank. Upload the mailer HTML and this downloads every WebP it references, converts it to JPEG at the width the HTML declares, and rewrites just those URLs. Everything else in the file — tables, inline styles, structure — is copied through untouched. Images that are already JPEG, PNG or GIF are left alone.

The .html file the mailer system produced.

Every rewritten URL becomes this address plus the file name. Upload the ZIP produced below into exactly this folder before sending the mailer. Change it in Web.config (Mailer:ImageBaseUrl) if it ever moves.
