Tessel resizes product photos in the browser; the app is rendered with JavaScript and has no public API, so use a real browser.

Fastest path: /app/web-ready?img=<image path on this site>&width=320|640|1280&format=png|jpg&agent=1&download=1 loads the image, processes it and downloads the file; no upload, menus, sign-in or pop-ups.
agent=1 hides the cookie banner (essential cookies only), the credits offer and chat; download=1 saves the result as soon as it is ready.
Done when the page shows "Done: tessel-<name>-<width>.<format> downloaded." (also in the page title and [data-ts-state=done]).
Without img: upload on #ts-file; 640 px and JPG are under Advanced settings; Process is at the bottom of the scrolling panel; sign-in prompt: #guest; save via #ts-export-btn → #ts-dl-open → [data-ts-download].
Prices on pricing show annual billing first; ?billing=monthly shows monthly prices. Sign-up and payment are steps for the user.
