Ad Character Limit Checker — free online
You write an ad, paste it in, and it gets cut off mid-sentence. Every platform has its own character limit, and they're all different, so you end up counting by hand or guessing. We added a free tool that does it for you — Ad Character Limit Checker — right in your browser.
What it does
Type your ad headline or description and it instantly shows how it measures up against the limits for Google, Meta, LinkedIn, X, and TikTok — all side by side. You can see at a glance which platforms your text fits and which ones will trim it, so you can trim it yourself before it goes live.
Nothing leaves your device
The whole thing runs in your browser. Your headlines and descriptions are never uploaded and never saved anywhere. When you close the tab, nothing stays behind.
How to use it
- Open Ad Character Limit Checker.
- Type or paste your ad headline or description.
- Look at the side-by-side counts and adjust your text until it fits every platform you need.
It's free with no limit. There are more small tools on the Apps page.
