Posting the same content across multiple social platforms means checking it against each platform's own character limit — X/Twitter, Instagram captions, LinkedIn posts, and others all enforce different maximums.
This tool checks your pasted text's character count against several major platforms' commonly cited limits simultaneously, showing at a glance which platforms your post fits within and which would require trimming.
This is useful when repurposing the same core message across several social channels, letting you see immediately which version needs shortening for a specific platform before you start manually adjusting text for each one.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.

This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
If you find yourself needing this often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.
Because there's no sign-up or installation step, you can jump straight from a search result to a working tool in a couple of seconds.
Frequently asked questions
Do these limits ever change?
Yes, platforms occasionally adjust their character limits, so treat these as commonly cited reference figures and verify against the platform's current official limit if precision matters for your specific use case.
Does this count emoji or links differently, like some platforms do?
This tool counts raw characters; some platforms count emoji or shortened links differently in their actual limit enforcement, so treat this as a close approximation rather than the platform's exact internal count.
