Why does Instagram sometimes collapse my blank lines into one giant paragraph?

Instagram's text parser often strips trailing spaces at the end of lines or collapses consecutive standard newline characters. When you copy from ToolBuddy, we normalize line breaks and inject clean Unicode braille/zero-width spacing on blank lines so your paragraph gaps stay intact without needing ugly periods (`.`) between lines.

How does bold and italic text work on Instagram if there is no bold button?

Our tool maps standard English letters (A–Z, a–z, 0–9) to their official Mathematical Alphanumeric Symbols in the Unicode standard (such as 𝗕𝗼𝗹𝗱 and 𝘐𝘵𝘢𝘭𝘪𝘤). Because these are distinct Unicode characters rather than HTML tags, they copy and paste directly into Instagram captions and bios.

Does Unicode bold text affect Instagram SEO or screen readers?

Yes—good question! Screen readers and search indexers read mathematical Unicode characters differently from plain ASCII letters. Best practice is to use Unicode bold selectively for short section headers or visual callouts, while keeping your main keywords and core sentences in standard plain text.

Where does Instagram cut off captions with '...more'?

In the main mobile scrolling feed, Instagram shows roughly the first 125 characters (spanning 1 to 2 lines next to your username) before hiding the rest behind '...more'. Make sure your strongest curiosity hook is in those first 100 characters.

What is the maximum length of an Instagram caption?

Instagram enforces a hard limit of 2,200 characters and 30 hashtags per caption. Our live counter tracks both in real time.
