What is Hashtag Generator?

Hashtag Generator is a free tool that instantly turns plain text into hashtags. Each line of input becomes one hashtag — in CamelCase or lowercase format. All processing happens locally in your browser.

What is the difference between CamelCase and lowercase hashtags?

CamelCase hashtags capitalize the first letter of each word (e.g., #SocialMedia), making them easier to read. Lowercase hashtags use no capitals (e.g., #socialmedia), which is a common style on many platforms.

Does Hashtag Generator collect my data?

No. All text processing happens locally in your browser. Your data never leaves your device. We only collect anonymous traffic statistics — no cookies, no ads, no personal tracking.

Does it work offline?

Yes. After the first load, Hashtag Generator works fully offline without any internet connection.

Create Hashtags from Text Instantly

Hashtag Generator turns any plain text into ready-to-use hashtags in seconds. Paste your topics — one per line — and choose CamelCase or lowercase format. All processing happens locally in your browser — your data never leaves your device. No registration, no ads, no limits, forever free.

How to Use

Paste your text: Enter one topic per line in the text area above. Each non-empty line becomes one hashtag.
#CamelCase: Capitalizes the first letter of each word and removes spaces — e.g., "social media" → #SocialMedia. Easier to read on any platform.
#lowercase: Converts all characters to lowercase and removes spaces — e.g., "Social Media" → #socialmedia. Common style on Instagram, Twitter/X, and TikTok.
Horizontal / Vertical: Toggle between hashtags displayed on a single line (space-separated) or stacked one per line. Switch at any time without regenerating.
Copy: Copies all generated hashtags to your clipboard, ready to paste anywhere.
Delete: Clears both input and output so you can start fresh.
Theme: Switch between Light, Dark, and Auto to match your preference or device setting.

CamelCase vs. Lowercase — Which to Use?

Both formats are widely accepted, but they serve different contexts:

#CamelCase (e.g., #DigitalMarketing) improves readability for multi-word hashtags and is recommended for accessibility — screen readers can distinguish separate words more easily.
#lowercase (e.g., #digitalmarketing) is the dominant style on Instagram and TikTok, where hashtag matching is case-insensitive regardless.

How It Works

Each non-empty line in the input is treated as one hashtag topic. The tool strips leading and trailing whitespace from each line, collapses internal whitespace, removes characters that are not valid in hashtags (special symbols, punctuation), and prepends the # symbol. CamelCase uses Unicode-aware capitalization so accented and non-Latin characters are handled correctly. Lowercase uses toLocaleLowerCase() for proper Unicode case folding. No server calls, no external libraries, no AI.
