02 / PLATFORM LIMITS

One draft. Every platform.

See which post, caption, or description fits. Colored bars flag overages before you publish.

Limits are useful publishing guides, not guarantees. X has weighted characters and links; Bluesky uses visible characters; TikTok's API counts UTF-16 units; YouTube descriptions have a byte limit. Account types, apps, and server rules may differ. Platform names are for identification only; Glyphometer is not affiliated with or endorsed by these services. Learn about counts.
03 / SMART FORMATTING

Little fixes. Big polish.

Select as many fixes as you need. Preview changes before applying, and undo anytime.

Smart word corrections are intentionally conservative. Some phrasing is ambiguous; always review important text before publishing.

04 / POST PREVIEW

See the first impression.

Choose a platform to preview your opening lines. Actual feed truncation varies by screen size and app.

A BETTER WRITING ROUTINE

How Glyphometer helps you post smarter.

01

Draft anywhere, edit here

Paste a caption, comment, headline, or update. Glyphometer measures words, visible characters, underlying Unicode units, and bytes without uploading your writing.

02

Compare your limits

Every network has its own rules. Check a short post against X, Bluesky and Threads or size longer copy for Instagram, LinkedIn, Pinterest, TikTok, and YouTube.

03

Polish, preview, copy

Clean up unusual punctuation, doubled words, emojis and encoding glitches. Preview the result, apply only what you need, and copy or save the finished text.

What exactly is a “character”?

An emoji can be made from multiple Unicode code points even when it looks like one symbol. Glyphometer uses a modern browser's grapheme segmentation for its visible-character metric. Other metrics include JavaScript UTF-16 units and UTF-8 bytes because some publishing APIs measure those instead.

For X, our weighted estimate treats URLs as 23 characters and many emoji/non-Latin characters as two. It's designed for quick drafting and may differ in edge cases from X's own composer. Always check the final post in the platform before publishing.

Can an automatic text fixer be perfect?

Some errors are obvious (“your welcome” is usually “you're welcome”). Others require understanding the sentence. Rather than rewrite meaning, Glyphometer uses a small, explainable set of conservative fixes for homophones and shorthand.

Formatting tools like HTML encoding and diacritic removal can be intentionally destructive. Use the before-and-after preview and undo buttons, especially for names, quotations, and multilingual writing.

GOOD TO KNOW

Frequently asked questions.

Does Glyphometer upload or store my text online?

No. The counter and formatter run in your web browser. Your draft is autosaved on this device using browser local storage so you can pick up where you left off. Clearing browser storage or using Clear removes the local draft. If ads are enabled by the site owner, advertising partners may independently process data according to the site's privacy policy.

Why don't all the platforms count my text the same way?

Some services weigh URLs, count UTF-16 units or UTF-8 bytes, or treat connected emoji as single visible characters. We show each platform's approximate publishing metric and the general-purpose counts so you can compare them.

Does Remove Emoji also remove text emoticons like :) ?

No. It removes Unicode emoji and emoji sequences. Plain-text faces such as :) or <3 are kept, because those are ordinary characters and punctuation.

Can I undo formatting changes?

Yes. Each applied batch is added to the editor's undo history. You can undo and redo changes while this page remains open, or preview the selected tools without changing anything.

Is it completely free to use?

Yes. You don't need an account, subscription, or extension. The website is lightweight and works on modern desktop and mobile browsers.
