Social media tools
Tools for preparing posts: checking how a link will look when shared, planning a feed and styling text.
Before you post
The Twitter Card Preview fetches your page from the Fix42 server and shows how the link will look on X, Facebook, LinkedIn and Discord, which is the quickest way to catch a missing image or title. The Instagram Grid Planner lets you drag posts around to see your profile grid before you publish, in your browser. The YouTube Thumbnail Extractor shows the thumbnail sizes YouTube serves for a video, which is handy for your own channel and for reference.
If a link preview still shows an old image after you fixed your tags, the platform has probably cached the old version. Facebook and LinkedIn both have their own inspector pages that force a fresh fetch, and X refreshes after a while on its own. The Twitter Card Preview reads your page fresh every time, so it shows what your tags say right now.
Styled text
The LinkedIn Post Formatter, Fancy Text Generator and Upside Down Text all use Unicode characters that look like bold, italic or flipped letters. They paste anywhere, but screen readers may read them oddly, so use them for a word or two of emphasis rather than whole posts. The LinkedIn formatter sticks to bold, italic and a few list styles that suit a professional feed; the fancy text generator has many more decorative styles for bios and captions. The Emoji Keyboard, Morse Code Translator and Text to Binary converter are simple copy-and-paste helpers.
