Hashtag Generator
One tool for every platform, with the right number of tags for each. 100% free, no signup. Everything runs in your browser.
The number of hashtags that works is different on every platform, and it is different by a lot. Thirty is normal on Instagram and looks unhinged on X, where one or two genuinely perform better than five. YouTube shows exactly three above your title and switches all of them off if you use more than fifteen. Facebook barely reacts to them at all. This hashtag generator handles all seven platforms in one place: pick where you are posting and the limits, the advice and the number of tags all change to match. If you only ever post to one place, the dedicated tools linked below go deeper on each.
How to use
- Describe your post in plain words. The tool reads what you wrote rather than needing a keyword list.
- Check which topic it matched. It shows you its guess so you can correct it in one tap instead of wondering.
- Choose the platform. This is the step that changes everything: the cap on the slider, the advice underneath, and how many tags you get.
- Set the count. The slider physically cannot exceed what the platform allows, so you cannot accidentally build a set that gets ignored.
- Press Build, tap anything you do not want, then copy the whole set or one group at a time.
Why use our hashtag generator?
Seven platforms, seven different answers, and most hashtag tools give you one. That is why so many people end up pasting an Instagram sized block onto TikTok or X, where it reads as spam and costs them engagement rather than earning it. Switching the platform here rewrites the advice line, so the reasoning is visible rather than hidden: you can see that YouTube only surfaces three, that X drops off past two, and that Facebook is largely indifferent.
The other half is the split between big, medium and small tags, which is weighted differently per platform because the platforms behave differently. Instagram rewards a spread across reach levels. TikTok mostly wants to know what category the video is in. YouTube needs its three visible tags to be the clearest search terms available. Getting that weighting right is the part a generic list of thirty tags can never do, whichever platform you paste it into.
Who is this tool for?
Anyone posting the same content in several places uses this as the one stop, adapting a caption from Instagram to TikTok to LinkedIn without keeping three sets of rules in their head. It is also the fastest way to learn those rules, since the advice changes in front of you as you switch.
If you only post to one platform, the dedicated tools are better tuned: Instagram for the thirty tag mix, TikTok for the three to six that categorise a video, YouTube for the three that show above your title, X for the one or two that beat a long list, and Facebook for an honest account of how little they do there. Before publishing, the hashtag counter checks the finished caption against whichever limit applies.
Frequently asked questions
Instagram allows 30, and 8 to 15 chosen well beats all 30 broad. TikTok works on 3 to 6. YouTube shows 3 above the title and ignores everything if you pass 15. X performs best on 1 or 2. LinkedIn takes 3 to 5 at the end of a post. Facebook, 2 or 3, though they do very little there. Pinterest treats them as keywords rather than links.
Because the platforms genuinely differ, in their caps, in how hashtags are displayed, and in what their audiences read as spam. A single number for all of them would be wrong for at least five of the seven.
The subject can carry across; the quantity and the format should not. Taking a thirty tag Instagram block to X is the most common version of this mistake and it visibly costs engagement.
No, and nothing free does so honestly any more. The platforms stopped publishing those numbers, so anything claiming them is scraping and breaks quietly. This applies the structure and the rules instead, which is the part most sets get wrong regardless of the counts.
This one covers all seven and is built for switching between them. The dedicated tools start with the right count already set, weight the tag mix for that platform specifically, and their guidance goes deeper into how that one platform actually treats hashtags.
No. The hashtag data and every calculation live in your browser. Nothing is uploaded and no account is required.
