100% Private100% PrivateImage Zippy is a free browser tool site with no account system, so there is no in-site messaging or support account to sign into.
A contact form for this site will be added later. Until then, this page does not publish a contact email and no email address has been invented for it.
If a tool fails on your device, the details that help are: which tool page, your browser, and the image type and size you tried. Keep a copy of the original image, because tools here never upload it anywhere, so a failed file cannot be recovered from the site.
