Posting on social media means juggling a lot of small jobs: finding hashtags, fitting a bio into 150 characters, checking whether a thumbnail will crop badly, working out if last week’s post did well. sociallyhive puts a free tool on each of those jobs, so you can get the answer in a few seconds and get back to making things.
What you’ll find here
There are 32 tools covering Instagram, TikTok, YouTube, LinkedIn and Facebook. They fall into a few groups:
- Generators for hashtags, captions, bios, usernames, titles, tags and descriptions, like the Instagram hashtag generator.
- Calculators for engagement rate and rough creator earnings, like the engagement rate calculator.
- Text tools that count characters and check your post against each platform’s limit.
- Image tools that resize pictures, check thumbnails and preview how a post will look.
- Reference guides for image sizes and story or reel dimensions.
- Fun extras such as the fancy text generator and an emoji picker.
How we build the tools
Every tool runs in your browser. The text you type and the images you load stay on your device and are not uploaded to us. You don’t need an account, there is no sign-up wall and there is no limit on how often you use them.
Where a tool gives you a number, it also shows the formula behind it, so you can check our working. Our How We Calculate page explains each one in plain words.
How the site stays free
We want the tools to stay free for good. To pay for hosting and development, the site may carry advertising. Ads will never sit inside a tool’s result or change what a tool tells you.
