About Social Media

Growing an audience means sweating the small details that platforms quietly enforce: the character limit on a caption, the exact image size for a banner, the link preview that decides whether a post gets clicked. ToolsHub pulls the everyday tasks of creators, community managers, and marketers into one toolkit so you can publish faster and look more polished.

Writing comes first. The Social Media Character Counter checks a caption or bio against the limits for each network before you hit post, the Hashtag Generator suggests relevant tags, and the Keyword Density Checker keeps your copy focused. When you want to know how a post will land, the Open Graph Preview and the Twitter Card Generator show the title, description, and thumbnail people will actually see when your link is shared.

Visuals and measurement round out the set. The Social Media Image Resizer crops artwork to the right dimensions for every feed and story, the Social Media Post Mockup helps you preview a layout, and the YouTube Thumbnail Downloader fetches public thumbnails from a video. To track performance you can run the Engagement Rate Calculator, estimate revenue with the YouTube Earnings Calculator, tidy links with the UTM Campaign URL Builder, and check handles with the Username Availability Checker.

Most of these tools run right in your browser, so your drafts and images stay on your device. A couple are different by necessity: the YouTube Thumbnail Downloader and the YouTube Tag Extractor fetch public data about a video through our server, since that information lives on YouTube rather than your machine. Everything is free and needs no account—open a tool, paste your text or link, and get a result you can use immediately.
