About this social post character counter
Check how long your post is against the character limit of the platform you're posting to. Paste your draft, choose X/Twitter, Threads, Instagram, LinkedIn, or Facebook, and this tool counts Unicode characters — counting each emoji as one character, not by UTF-16 code units — and shows how many you have left or how far over the limit you are. Use this workspace to prepare a result you can review before putting it to use. All processing takes place on your device, without an account or an upload of your inputs. Check the examples to understand the expected output, read the limitations for the supported scope, and reset the form when you want to start a separate task.
How the social post character counter works
Counts Unicode code points (so most emoji count as one character each, not two or more) and subtracts from the selected platform's published character limit.
