Hashtag generator
Generate the right hashtags in seconds
The right hashtags are half the reach. Type a topic or paste your caption and this free generator turns your keywords into relevant hashtags, then rounds them out with a curated niche pack for your industry. It runs entirely in your browser — no login, no app, no limits — so you can generate, tweak and copy as many times as you like. Pick Instagram, TikTok, YouTube or X and it keeps every suggestion inside that platform's own hashtag limit.
How to generate hashtags
Type a topic or paste a caption into the box above, choose the platform you're posting to, and add a niche pack if you want more reach. Press Generate and you'll get a mix of keyword hashtags and popular niche tags. Copy them all, copy them as a list, or tap any single tag to copy it on its own.
Tune for each platform and stay within limits
Instagram allows up to 30 hashtags, YouTube reads the first 15, and X posts do best with just two or three. Pick your platform and the generator caps suggestions to that limit, shows a live tag count and character total, and warns you before you overload a caption. No guesswork — just paste, generate and post.
