Why does my formatting disappear when I paste into LinkedIn?

LinkedIn's post box is plain text. It keeps line breaks and emoji but drops bold, italics, headings and bullet styles that come from Markdown or rich text, and it collapses an empty line. This tool rewrites those marks as Unicode characters LinkedIn treats as ordinary text, and puts an invisible braille-blank character on separator lines so your paragraphs stay apart.

Does this tool use AI?

No. Every conversion is a fixed set of text rules that run in your browser. Nothing is sent to a server, no model is called, and nothing you paste is stored or logged.

Is my post uploaded anywhere?

No. The formatter runs entirely on your device. The page sends no request containing your text and has no accounts or analytics on what you paste.

What are AI watermarks and can they be removed?

Assistants often leave invisible characters behind: zero-width spaces, word joiners, tag characters, soft hyphens and look-alike spaces, sometimes used to mark machine-written text. They survive copy-paste and can make a post look or behave oddly. The formatter detects and removes them, including bold letters written as Unicode symbols, and tells you exactly how many it removed.

How does the AI word finder work?

A fixed list of overused assistant phrases, including delve, leverage, robust, "in today's fast-paced world" and "I hope this helps", is matched and shown with a plain-English replacement. You can undo any single replacement before you post. No model is involved.

Does the bold really stay bold on LinkedIn?

It looks bold because bold-shaped Unicode letters are pasted as plain text. LinkedIn applies no real styling, so it is an appearance, not a format. Screen readers may read those letters differently, so use the plain option when accessibility matters more than looks.

What is the LinkedIn character limit?

LinkedIn allows 3,000 characters per post. The counter shows how much of the 3,000 characters you've used; some mobile keyboards count certain Unicode letters as more than one character, so stay slightly under the limit.

How much of my post is visible before "see more"?

About 200 characters on desktop and fewer on mobile. The preview shows where that cut falls, so put the hook in your first two lines.

Should I move links to the first comment?

Many creators do it because link posts can reach fewer people. Set Links to "move to first comment" and the tool hands you a ready-to-paste comment plus a post without the URL. It is a workflow choice, not a LinkedIn guarantee.

How it works

The problem

Why formatting gets lost in LinkedIn

LinkedIn's post box is a plain-text field. It keeps line breaks and emoji, but it throws away the styling that Markdown or rich text carries with it: bold arrives as literal asterisks, a heading keeps its hash mark, a bullet stays a hyphen, and a genuinely empty line is collapsed so two paragraphs run together.

Copying out of ChatGPT, Claude, Gemini, Notion or Google Docs makes it worse, because those editors wrap structure in Markdown and every assistant writes its own preamble. What looked like a finished post arrives as a wall of symbols.

The invisible separator

A paragraph break in a LinkedIn post is really just a newline. Leave a truly empty line and LinkedIn collapses it. A line that holds exactly one U+2800 BRAILLE PATTERN BLANK character looks empty but is a real character, so LinkedIn keeps it and your paragraphs stay apart.

That is why this tool puts one U+2800 on every separator line: not at the start, not at the end, only between paragraph blocks. If you would rather see the divider, choose the visible dash line instead.

No workaround is perfect. Bold here is an appearance made of Unicode letters, not real formatting, and some screen readers read those letters differently. LinkedIn apps and browsers also wrap lines differently. Choose the plain ASCII option when accessibility or searchability matters more than looks. Rich-text paste keeps bold, headings and lists, but colour, fonts and other style-only emphasis are dropped. LinkedIn cannot carry them anyway.

How it works

Three steps, one paste

Nothing leaves the page and nothing is saved. The rules run in your browser as you type.

Paste your post

Drop in the raw text from ChatGPT, Claude, Notion or your own draft. Markdown is detected automatically, and plain pastes work too.

Check what was changed

Hidden characters, fake-bold letters and known AI phrases are listed with a plain-English replacement. Untick keep on any row to restore the original.

Copy into LinkedIn

The output is plain text LinkedIn accepts. Press Copy for LinkedIn, paste once, and the bold, bullets and paragraph gaps stay.

What it does

Everything a paste needs

Fixed text rules, run locally. No model, no upload, no account.

Preserves line breaks

Paragraphs stay apart with an invisible separator line, so LinkedIn does not crush them into one block.

Bold and italic that survive paste

Markdown emphasis becomes bold-shaped and italic-shaped Unicode letters, which LinkedIn pastes as ordinary text.

Nested bullets and numbered lists

List markers become real bullet symbols across three nesting levels, while numbered lists keep their numbers.

Removes hidden AI watermarks

Zero-width spaces, tag characters, soft hyphens, look-alike spaces and fake-bold Unicode letters are stripped and counted.

Finds and rewrites AI words

A fixed list of overused assistant phrases is matched and shown with a plain-English replacement, and each one can be undone.

Strips the AI preamble

Lines like “Sure, here is a post” and “I hope this helps” are removed, so the paste starts with your actual hook.

Counter and see-more preview

A live 3,000-character counter and a preview of the first 200 characters show where LinkedIn will cut the post.

Links moved to the first comment

Optionally strip URLs from the post and get a ready-to-paste first comment instead. It is a workflow choice, not a guarantee.

Nothing leaves your browser

The script runs on your device. There is no upload request, no account, and no analytics on what you paste.
