How to use it
Here is the short version of using Social Character Counter.
- Paste your text — Counts update live, including hashtags, mentions and links.
- Compare the limits — Each row shows used characters, the maximum and how far over you are.
- Trim and re-check — Edit the text until the platforms you care about are inside their limits.
Features that matter
What Social Character Counter does well.
- Nothing leaves your device — The work happens in your browser tab. There is no upload endpoint in this app, so your files and text cannot be stored, logged or seen by us.
- No upload wait — You skip the round trip to a server entirely. Results are limited by your own CPU, not by network speed or queue size.
- Free, no account, no quotas — No sign-up wall, no watermark, no daily limit. Optional accounts only exist to save favourites and presets across devices.
Frequently asked questions
Is my caption safe to use here?
Yes. This tool runs entirely in your browser using JavaScript. Nothing you paste or open is sent to a server, and the page keeps no copy after you close it.
Do I need to create an account?
No. Every tool is fully usable without signing in. An account only adds saved favourites and reusable presets.
Does it work on a phone?
Yes. The interface is mobile-first with large touch targets and a stacked layout, so it works on phones and tablets as well as desktops.
Do links count as 23 characters on X?
X wraps links with t.co and counts every link as 23 characters, regardless of its real length. This counter uses raw character count, so leave headroom for links.
Why do emoji count differently?
Many emoji are two UTF-16 code units long, so JavaScript's length counts them as two. Platforms may count them as one or two depending on their implementation.
