Growing on social media is part craft, part logistics — you need the right words, the right hashtags, the right image sizes and copy that fits each platform's limits. CrispToolHub's free social media tools handle the fiddly parts so you can focus on creating, with no sign-up and nothing stored.
The Instagram bio generator turns a few details about you into polished bio options with line breaks, emojis and a call to action — in a free template mode or with optional AI. The YouTube title generator does the same for videos, scoring each suggestion for click-through potential so you can pick the strongest hook.
The hashtag generator suggests 30 relevant tags by topic and niche, mixing high-volume, medium and niche tags for the best reach, and lets you copy a selected set. The character counter shows live progress bars against every platform's limit — from X's 280 characters to LinkedIn's 3,000 — so your post never gets cut off.
Finally, the social media image resizer crops and resizes any photo to the exact dimensions Instagram, YouTube, LinkedIn, X and Facebook expect — feed posts, stories, thumbnails, covers and profile pictures — all in your browser, with no upload. Pick a tool above and start posting like a pro.

FAQ
Frequently asked questions
Are these social media tools free?
Yes — every tool is free with no sign-up. The character counter, hashtag generator and image resizer are 100% client-side, and the Instagram bio and YouTube title generators include a free unlimited template mode plus an optional AI mode (5 generations per day) powered by Google Gemini.
Do I need an account to use them?
No account is required for any tool. The image resizer processes your photo entirely in your browser — it's never uploaded — and the text tools run locally too. Only the optional AI generation sends your short prompt to our secure proxy; nothing is stored.
What social platforms do the tools cover?
The character counter and image resizer support Instagram, X (Twitter), LinkedIn, YouTube, Facebook and TikTok with their current character limits and recommended image dimensions, and the hashtag generator tailors suggestions for Instagram, X, LinkedIn and TikTok.
Are the AI features any good for engagement?
The AI Instagram bio and YouTube title generators use proven copywriting hooks — curiosity gaps, numbers, strong verbs and clear calls to action — to suggest options you can refine. They're a fast starting point, not a guarantee; always tweak the output to match your voice and stay honest with your audience.
How current are the platform size and character limits?
We keep the limits and image presets updated for 2026, including the 280-character X limit, 2,200-character Instagram caption, 150-character Instagram bio, and the recommended feed, story, thumbnail and cover dimensions. Platforms occasionally change these, so treat them as reliable guidance.
