Platform copy checker
Fit copy to the field before you publish.
A focused counter for titles, descriptions, ads, metadata, and platform copy. One text box, clear limits, source links where public rules exist.
How TextFit works
Specific pages, same fast tool.
TextFit gives concrete URLs to concrete writing jobs. A YouTube title page, a Google Ads headline page, and a WeChat title page all open the same counter with the right preset already selected. Public official limits are linked from the result card; writing-guide presets are labeled as practical ranges instead of hard rules.
FAQ
Useful before publishing.
Does TextFit upload my text?
No. The current version counts text in your browser with local JavaScript.
Why are some presets verified and others guides?
Some platforms publish exact field limits. Others change UI behavior or do not publish a stable public limit, so TextFit labels those as writing ranges.
What is weighted width counting?
Some ad systems count full-width characters as 2. TextFit shows that weighted count next to normal characters and bytes.
Privacy
Privacy notice
TextFit counts pasted text in your browser. The current version does not upload your source text to a Solidscreen server. The site may use Cloudflare Web Analytics and Google AdSense, which can process standard visit, device, and advertising data according to their own policies.
Terms
Terms of use
TextFit is provided as a practical browser tool. You are responsible for the text you paste, the results you use, and the rules of any platform where you publish. Platform limits can change, so source links and writing ranges should be checked when accuracy matters.
