Free social media tools
Small, fast tools for everyday social media work. They are free and you do not need an account to use them.
The tools
- Character counter: paste your text and see instantly whether it fits X (280), Threads (500), LinkedIn (3,000), Instagram and TikTok (2,200) and the rest.
- UTM builder: add source, medium and campaign tags to your links so your web analytics show which post sent each visitor.
- Social media limits: characters, images, video and media requirements for each network, in one table.
When to use each one
Use the character counter when you write one message for several networks: it shows at a glance where you need a shorter version. Use the UTM builder whenever a post links to your website, so you can compare networks in analytics; the UTM parameters entry explains each field. Keep the limits table open when you plan carousels and videos, since image counts vary a lot: 1 on Pinterest, 4 on X, 9 on LinkedIn, 10 on Instagram, Facebook and Threads, up to 35 on TikTok in Postika.
From tool to calendar
The same limits are checked inside Postika when you schedule a post, so text that passes the counter will also pass in the app. If you plan regularly, the scheduler saves the step of copying text between tools, and your AI can draft posts that already respect every limit. Plans start at €29 a month; see pricing.

Frequently asked questions
Are the tools really free?
Yes. They are free to use and do not require an account. They exist because we needed them ourselves while building Postika.
Do the limits match what Postika enforces?
Yes. The tools use the same limits Postika checks before scheduling. Where a network officially allows more in some formats, the limits page notes the difference.
Why does my post fit on one network but not another?
Each network sets its own limits. A 400-character post fits Threads (500) and LinkedIn (3,000) but not X (280). The character counter shows every network side by side.
