Hashtag Cleaner sanitizes and normalizes hashtag lists by removing duplicates (case-insensitive), stripping invalid characters, fixing common formatting issues like double # symbols, removing spaces within tags, and standardizing capitalization to your preferred style (lowercase, Title Case, or camelCase). It validates hashtags against platform-specific rules — Instagram's 30-tag limit, Twitter's recommendation of 1-2 tags, and LinkedIn's 3-5 tag sweet spot.
Social media managers maintaining hashtag libraries, content creators organizing saved hashtag groups, and marketing teams standardizing brand hashtag usage. The tool runs entirely in your browser — your data never leaves your device.
