# Free social media tools: counters, previews and more

Free tools that run in your browser: character counters, a post previewer, a thread splitter, UTM builder, image and video checkers and more.

Nineteen free tools for people who post. Count characters the way each network does, preview and split posts, tag links, crop images, check videos and find your best hours, work out your engagement rate and compare scheduler prices. Every tool runs in your browser, needs no account and uploads nothing.

Each tool uses the same limits and counting rules as the 1Post composer, so a post that passes here will not be refused for length when you publish it. Questions about a tool: hello@get1post.com.
