Frequently asked questions
How this tool works, what it cannot do, and what happens to what you put into it.
How does X count characters?
X counts every character in your tweet, including letters, numbers, spaces, and punctuation. URLs are counted as 23 characters regardless of their actual length. Most emojis count as 2 characters each.What's the best character count for engagement?
Tweets between 71-100 characters typically get 17% more engagement than longer tweets. Keeping tweets under 250 characters leaves room for retweets with comments and increases shareability.Do hashtags and mentions count toward the character limit?
Yes, hashtags and @mentions count toward your 280-character limit. Each character in the hashtag or username counts, including the # and @ symbols.How are emojis counted in tweets?
Most emojis count as 2 characters due to how they're encoded. Some complex emojis (like flags or emojis with skin tones) may count as more. Our tool tracks emoji usage so you can plan around it.What happens if I exceed the character limit?
X won't let you post tweets over 280 characters. You'll need to edit your content, create a thread, or use the long-form posts feature if you have access to it.Is my data private?
Yes. This tool does its work in your browser, so whatever you type, paste or upload stays on your device. Nothing is sent to our servers, which is also why it keeps working if you go offline after the page has loaded.Is this really free?
Yes. Every tool here is free with no account, no credit card and no usage cap. They exist so that the people who need our scheduling product find us, which only works if the tools are genuinely useful on their own.Do I need an account?
No. Open the page and use it. An account is only for OctoSpark itself, where you plan, schedule and publish a whole calendar rather than fixing one post at a time.Can I use the output commercially?
Yes. Anything you produce here is yours, including for client and commercial work. We claim no rights over it and we do not watermark it.
