Clean duplicate hashtags and organize tags.
How does Hashtag List Cleaner work?
Hashtag List Cleaner takes a block of tags separated by spaces, adds a leading # to any tag missing one, and removes duplicates, giving you a clean, ready-to-paste hashtag list.
How to use it
- Paste your tags separated by spaces, with or without # symbols, for example: #marketing #seo marketing growth.
- The cleaned, deduplicated list is generated automatically below.
- Copy it into your social media caption.
Common use cases
- Cleaning up a hashtag list before publishing a social media post.
- Merging hashtag suggestions from multiple sources without duplicates.
- Standardizing tags to all start with # before pasting into a scheduler.
Frequently asked questions
Does it work with tags separated by commas or new lines?
Tags are split on whitespace, so tags separated only by commas without spaces may not split correctly — separate each tag with a space.
Is the tag list case-sensitive when removing duplicates?
Yes — #SEO and #seo are currently treated as different tags.
