Free TikTok tools

Explore free TikTok tools to create stylish bios, captions, usernames, hashtags, and fonts. Easy to use, mobile-friendly, and no signup required.

Plan copy before you open the app

Draft bios, hooks, and tag ideas before you open the app. Generators mix local templates with your keywords—they are not connected to TikTok or any paid AI API.

Unicode “fonts” are characters

Unicode “font” tools output special characters; test on your phone because some devices show boxes. Character and script helpers explain API vs in-app limits where that matters.

Hashtags and trends

Hashtag suggestions on Case Modify are thematic ideas, not live trend data. Pick a small set that matches the first seconds of your clip. Irrelevant tags often hurt more than they help.

Frequently asked questions

Short answers about privacy and how these tools work.

Does Case Modify connect to my TikTok account?

No. Tools run locally after the page loads. You copy text and paste it yourself.

Are generated usernames guaranteed to be free?

No. TikTok alone knows whether a handle is taken. This site does not check availability.

Do hashtag lists show what is trending?

No. Lists are topic-based ideas. TikTok’s discovery experience changes by the minute.

Why does my bio look different on another phone?

Unicode and line breaks render per device. Always preview in the TikTok app before publishing.

Does the character counter include emojis?

Yes—each emoji can count as multiple code units depending on where you paste. Use it as a guide, not a guarantee against TikTok’s own limits.

Can these tools post to TikTok for me?

No. Generators and counters only prepare text in your browser. You paste into TikTok yourself.

Do caption generators call TikTok’s API?

No. Suggestions use local templates and your keywords. Trend data and posting always happen inside TikTok.
