Frequently Asked Questions

What does the Threads Caption Formatter do?

It cleans and structures your caption — trimming messy spacing, grouping hashtags at the bottom, and showing a live character count against Threads’ 500-character limit.

What is the Threads character limit?

Threads allows up to 500 characters per post, including hashtags, mentions, and emoji. The counter turns red when you exceed that limit.

Is this the same as the TikTok Caption Formatter?

Similar layout, different limit. The TikTok Caption Formatter tracks a 2,200-character limit. This tool is tuned for Threads’ shorter 500-character posts.

Should hashtags go at the end?

Many creators put hashtags after the main caption so the hook stays readable in the feed. Use “Move hashtags to bottom” to separate body text from tags automatically.

Is my text stored or sent anywhere?

No. All formatting runs entirely in your browser.

Is this tool free and does it work on mobile?

Yes on both counts. The Threads Caption Formatter on draft21 is completely free with no sign-up required and works on all devices.
