ChangeTheHeaders

The author encountered an issue where dragging images from Safari sometimes resulted in WebP format, even when the original webpage displayed PNG or JPEG. This caused problems because the author prefers using PNG and JPEG for publishing images. The author investigated the issue and found that Safari's "Accept" HTTP request header influenced the image type served by websites. Jeff Johnson, the creator of the "StopTheMadness" Safari extension, explained the cause and developed the "ChangeTheHeaders" extension to solve the problem. The extension allows users to customize HTTP request headers, including the "Accept" header, to prioritize desired image formats. The author used "ChangeTheHeaders" to prioritize PNG, effectively preventing WebP downloads. The extension also allows customization of the User-Agent and Accept-Language headers. The ChangeTheHeaders extension works across all Safari platforms, including Mac, iPhone, iPad, and Vision Pro. It offers a set-it-and-forget-it solution for controlling image formats and other header-related issues. The extension is available on the App Store for a small fee. By adjusting the "Accept" header, the author successfully fixed the issue and gained control over image formats.
