Instagram Line Break Generator
Preserve line breaks and blank lines in Instagram, Threads, TikTok captions with invisible characters.
About this tool
Instagram Line Break Generator (instaline) fixes the problem where Instagram / Threads / TikTok / X strip blank lines from captions on save. By inserting zero-width Unicode chars (U+2063 Invisible Separator / U+200B Zero-Width Space / U+2060 Word Joiner) into each blank line, the apps no longer treat them as empty β your layout is preserved on paste. Includes a character counter for Instagram bio (150) and feed caption (2,200), platform-specific previews for Threads / TikTok / X, and auto-truncation of 3+ consecutive blank lines (spam-filter safe). 100% client-side; nothing is uploaded.
Use cases
Scenario 1
Preserve Instagram post layout
A traveler posting a multi-paragraph trip report keeps the intended blank-line breaks intact via zero-width insertion.
Scenario 2
Bio line break
For a 3-line Instagram bio, the tool applies the minimal zero-width combo that preserves line breaks within the 150-character cap.
Scenario 3
Long Threads post
For 500-char Threads posts that need readable paragraph breaks, the U+2063 default keeps everything intact.
Scenario 4
TikTok caption emphasis
Separate hashtags, key points, and CTAs in TikTok captions on different lines so viewers can scan fast.

Frequently asked
- Q. Why does Instagram strip blank lines?
- A. On save, Instagram / Threads / TikTok strip lines that contain only `\n`. By adding a zero-width character to each blank line, the apps no longer see them as empty.
- Q. Which char should I use β U+2063 / U+200B / U+2060?
- A. As of April 2026, U+2063 (Invisible Separator) is the most reliable. If older builds (iOS β€ 14 or Android β€ 9) misbehave, switch to U+200B. U+2060 (Word Joiner) is for preventing word splits, not line breaks.
- Q. Does it count against the character limit?
- A. Yes β zero-width chars count too. The counter shows visible vs real length so you stay within Instagramβs 150-char bio limit.
- Q. Any spam-filter risk?
- A. Patterns with 30+ blank lines per post can trip spam filters. The tool auto-shrinks 3+ consecutive blank lines to 2 by default.
