Text Word Wrap & Line Formatter
Text Word Wrap & Line Formatter: Wraps lines on word boundaries without breaking mid-word when possible.
About this text word wrap & line formatter
Wraps lines on word boundaries without breaking mid-word when possible Applies Unicode-compliant text transformations and parsing directly in the browser tab without data leakage.
Text processing & transformation mechanics
Splits input at whitespace and greedily places whole words into lines up to a positive integer width. Width defaults to 80; long words are never split and original whitespace is normalized.
Worked text manipulation example
Scenario: Clear the UI's initial width of 20 to use the function default of 80 JavaScript code units.
Sample input:
Second field:
Processing: With the second width field cleared, use 80 and move a whole word to the next line before it would exceed that length.
Illustrative output:
Character encoding & string length boundaries
Default width is 80 JavaScript string units. Long words are never split; original whitespace and line breaks are normalized.
Text formatting and transformations in Text Word Wrap & Line Formatter preserve character integrity. Check edge cases such as multi-line inputs and special characters before downstream use.
In-memory text processing boundary
String operations and Unicode manipulations in Text Word Wrap & Line Formatter execute entirely in local browser memory without transmitting input text.
Unicode Consortium & text formatting standards
Unicode Consortium standard annexes (UAX) and character encoding specifications:
- ECMAScript whitespace splitting and UTF-16 String.length.
- Local greedy whole-token wrapping with positive safe-integer width (default 80); not pixel, grapheme, or typographic line breaking.

Frequently asked questions
How does word wrapping choose line breaks?+
It splits text at whitespace and adds words until the next word plus one space would exceed the width, then starts a new line.
What happens with a width of 7?+
Set the width to `7` and enter `one two three`. The result is `one two` on the first line and `three` on the second.
Are long words split?+
No. A word longer than the chosen width stays whole on its own line; the tool does not hyphenate words.
Which widths are valid?+
A missing, `null`, or blank width is 80. A supplied width must be a finite safe integer; values below 1 become 1. Width is JavaScript string length, not rendered pixels.
