Good

Private: hashtag cleanup runs locally in your browser. Nothing is uploaded.

Flexible: paste plain tags, commas, line breaks, or full captions from any platform.

Safe: this tool does not scrape social platforms, log in, or call APIs.

Remove duplicate hashtags

Paste a caption, comma-separated tags, or one tag per line. Duplicate hashtags are removed case-insensitively so the final list is cleaner.

Choose copy-ready output

Switch between one-line, one-per-line, and comma-separated formats. Optionally keep the caption text above the cleaned tag list.

Private by default

The tool runs locally in the browser. There is no scraping, platform API connection, account login, or upload.
