Hashtag Cleaner & Deduplicator: the complete guide
A Hashtag Cleaner and Formatter extracts, deduplicates, and formats hashtags from unorganized social media captions, notes, and drafts. When managing Instagram, TikTok, LinkedIn, or YouTube campaigns, marketers frequently copy hashtag groups from previous posts, notes apps, or spreadsheets, leading to duplicate tags, irregular spacing, mixed casing, and broken punctuation. This tool extracts all valid hashtags, removes duplicates, normalizes casing, and formats them with your choice of spaces, commas, or line breaks.
Hashtag Limits Across Major Social Platforms
Platforms enforce varying hashtag thresholds: Instagram supports up to 30 tags (with 3-5 recommended for algorithmic reach), TikTok recommends 3-5 focused tags, LinkedIn works best with 3-5 industry tags, and YouTube allows up to 15 tags in descriptions. Deduplicating and formatting tags ensures you never exceed platform limits or trigger spam penalties.
Casing Styles and Accessibility (CamelCase)
CamelCase hashtags (e.g. #WebDevelopment instead of #webdevelopment) improve readability for screen readers used by visually impaired users. This tool allows toggling between lowercase, original casing, and clean formatted casing.
