Why this tool is useful
Use bordered text for README notes, terminal announcements, plain-text status messages or documentation callouts that must remain copyable.

Text Box Drawing Tool
Wrap one or more text lines in an ASCII, single-line, double-line or rounded Unicode border with configurable horizontal padding.
Ready. Your working data stays in this browser.
How it works
The widest Unicode line determines the interior width. Each shorter line is padded to that width and enclosed with the selected border characters entirely in JavaScript.
Practical example
Two lines reading Local processing and No upload become a consistently sized single-line Unicode box with one space on each side.
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.
