About social media tools
Every social platform has its own character limits, image dimensions, and formatting quirks. ToolJutsu's social media tools help creators and marketers stay within them: bio and caption counters, hashtag formatters and counters, platform-specific image resizers and croppers, username generators, and a bio-link page builder. They are quick, free, and run entirely in your browser so your draft posts are never uploaded anywhere.
Every tool in this category runs entirely on your device. Your files and inputs are never uploaded to a server — there is no server in the loop that touches your data. That makes ToolJutsu a genuinely private way to get everyday tasks done. New tools in this category go live as the project progresses; cards marked “Soon” are on the roadmap.
