Why this tool is useful
Use this formatter for plain-text reports, terminal notes or fixed-width drafts where complete lines need aligned left and right edges.

Text Line Justifier
Distribute spaces between words so each eligible line reaches an exact character width, while preserving blank lines and final short lines.
Ready. Your working data stays in this browser.
How it works
Each non-final line is split into words, then the browser allocates the exact number of required spaces from left to right. Lines that cannot be expanded safely remain unchanged.
Practical example
Set a width of 42 for a paragraph containing several words. Complete lines reach exactly 42 Unicode characters while its final line stays naturally short.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
