Line Break Converter — Facebook & Instagram

About

Tired of Facebook and Instagram squashing your nicely formatted posts into one giant paragraph the moment you paste them in? This extension fixes that.
 
When you paste text into a whitelisted site, Line Break Converter intercepts the paste, rewrites the empty lines with an invisible non-breaking space so the platform won't strip them, preserves runs of double-spaces, and inserts the result into the field for you — instantly, with no extra clicks.
 
WHAT IT DOES
 
• Preserves line breaks when pasting into Facebook posts, comments, and Messenger
 
• Preserves line breaks when pasting Instagram captions and bios
 
• Optional: automatically adds a blank line between paragraphs for that clean, readable promo-post look
 
• Preserves multiple consecutive spaces using non-breaking spaces
 
WHITELIST CONTROL
 
The extension only runs on sites you explicitly add to its whitelist. Facebook and Instagram are pre-configured. Add or remove any domain from the popup at any time. Every other site behaves exactly as it normally would — your pastes are untouched.
 
MANUAL CONVERTER
 
For sites you don't want to whitelist, the popup includes a paste-in/copy-out manual converter. Paste, click Convert & copy, paste the result anywhere.
 
PRIVACY
 
• No accounts, no logins, no tracking, no analytics.
 
• No data is sent anywhere. Your settings (on/off, whitelist, paragraph-spacing option) are stored in Chrome's built-in sync storage so they follow your profile across devices.
 
• The extension reads paste events only on whitelisted pages, transforms the text locally in your browser, and inserts it into the field. Nothing leaves your machine.
