What the cleaner fixes
A hashtag ends at the first space or symbol, so #self-care becomes a tag for "self" and #europe trip only tags "europe". The cleaner joins the words back together, removes punctuation, and drops repeats regardless of letter case, keeping the first one you wrote. You choose the case: keep it, make everything lowercase, or use CamelCase (#TravelTips), which is easier to read and to hear for screen reader users.

How many hashtags each platform allows
Only two platforms state a number. Instagram's developer documentation allows 30 hashtags per caption, and Instagram announced in December 2025 that it would gradually cut this to five. YouTube ignores all hashtags on a video that has more than 60, and shows up to three above the title. TikTok, Facebook, LinkedIn, Threads and Pinterest publish no hashtag limit, so the tool doesn't invent one.
The second number is Uplonic's own: when it publishes, it keeps the first hashtags in your list up to a cap per platform (for example 5 on TikTok and 15 on YouTube) and drops the rest from the end. Put the most specific tags first.
Sources and methodology
Numbers checked on October 18, 2026.
Platform limits are shown only where the platform states one: Instagram (30 in the IG User Media API; the cut to five is a reported announcement) and YouTube (more than 60 means all are ignored, up to 3 above the title). The Uplonic numbers are the caps the publishing step applies. Everything runs in your browser.
