Hashtag Formatter
Clean up a list of hashtags: add the # signs, remove duplicates and broken characters, choose lower case or CamelCase, limit the count, and lay them out in a line or for a first comment.
Hashtag Formatter: Tags written with # are picked out of the text; otherwise each word or comma-separated phrase becomes a tag. Spaces and punctuation are removed, since a hashtag ends at the first one, duplicates are dropped regardless of case, and tags made only of digits are left out. CamelCase joins phrases with a capital for each word, which screen readers and people read more easily. Runs 100% locally in your browser with zero server file uploads.

#travel #summer #photography
Removed 2 duplicates and 0 over the limit.
Hashtags end at the first space or punctuation mark, so #summer-vibes links only #summer; tags made only of numbers are left out. Check each platform's current limit on hashtags per post.
Choosing hashtags
A few specific tags that describe the post usually work better than many broad ones: a mix of one or two popular tags, a few niche ones, and any branded or event tag. Avoid tags unrelated to the content, which can make a post look like spam.
Check the length of the full caption with the social media character counter, and plan a profile's look with the Instagram grid maker.
Accessible hashtags
Screen readers read #SummerVibesInLisbon as separate words but #summervibesinlisbon as one long word, so CamelCase makes hashtags usable for blind and partially sighted followers at no cost.
How to use it
- Paste hashtags, plain words, or a whole caption.
- Choose the case, a limit, and the layout.
- Copy the clean hashtags into your post.

Frequently asked questions
Why use CamelCase hashtags?
#SummerVibes is easier to read than #summervibes, and screen readers pronounce the words separately instead of as one jumble.
Do hashtags work with accents and other alphabets?
Yes: letters from any language and underscores are kept; only spaces, hyphens, and punctuation end a hashtag.
Should hashtags go in the caption or the first comment?
Both work on most platforms; the block layout, with dots above the tags, keeps them out of sight in a first comment.
