Bio Character Counter — free online tool
You write a nice short bio, paste it into Instagram, and it gets cut off. Then you trim it for X, but it's too long for LinkedIn. Counting characters by hand and guessing each platform's limit is a small, annoying chore. We added a free tool that handles it for you — Bio Character Counter — right in your browser.
What it does
You type or paste your bio once, and it instantly shows how it fits every major platform — Instagram, X (Twitter), TikTok, LinkedIn, and Facebook — all at the same time. No switching tabs, no looking up limits, no guessing. You see right away where your text fits and where it's too long.
Nothing leaves your device
The whole thing runs in your browser. Your bio is never uploaded anywhere and nothing is saved. You can close the tab and it's gone. Nobody sees what you type but you.
How to use it
- Open Bio Character Counter.
- Type or paste your bio in the box.
- Read the count for each platform and trim until it fits.
It's free with no limit. There are more small tools on the Apps page.
