Word wrap text to width

Word wrap turns long, uneven text into readable lines that fit a chosen column width. Supply plain text and an integer width, and the tool reflows every paragraph while keeping words intact. Blank lines continue to separate paragraphs, so a multi-paragraph email or note keeps its structure. The result is deterministic and ready to paste into terminal output, source-code comments, plain-text documentation, issue trackers, or messages where predictable line lengths matter.

How wrapping to a column width works

Word wrapping solves a layout problem without rewriting the content. The tool reads the words in each paragraph from left to right and adds the next word to the current line when the word, its separating space, and the existing line fit within width. When they do not fit, it starts a new line before that word.

This means ordinary lines do not exceed the requested width and words are never cut in the middle. A single word that is itself wider than the limit is the deliberate exception: it remains whole on its own line because breaking an identifier, URL, filename, or technical token could change its meaning or make it impossible to copy. Whitespace inside a paragraph is normalized, so repeated spaces, tabs, and existing single line breaks become normal word separators.

Blank lines still identify separate paragraphs and the output retains a single blank line between them. This approach makes the tool useful both for unformatted prose and for reflowing text that was previously wrapped at the wrong width. It does not add hyphens, justify margins, detect Markdown, or paraphrase sentences.

The operation changes line placement only, making the output easy to inspect and repeat.

Choosing a useful width and reading the result

Choose width according to the destination rather than the size of the source text. Terminal logs and traditional email often benefit from moderately narrow lines, while code comments may need room for indentation and comment markers that you will add later. If the surrounding format consumes characters, subtract that prefix from the available column count before wrapping.

For example, a documentation system with a four-character comment prefix needs a text width four columns smaller than the final visual target. Empty source text is valid and returns no lines or paragraphs. Newlines are normalized to LF, making the same request stable across Windows, macOS, Linux, browsers, and edge execution.

Remember that width counts JavaScript string characters rather than rendered pixels. Proportional fonts give different visual widths to narrow and wide letters, so use this tool for column-oriented plain text, not pixel-perfect graphic layout. For fixed-width fonts, the character limit maps naturally to visible columns for most common text.

Reliable use in email, comments, and automation

For email drafts, wrap after composing and editing, because inserting words into already wrapped text can leave ragged short lines. Preserve intentional paragraph changes with blank lines, then pass the complete body in one request. For source comments, wrap the prose first and add language-specific prefixes afterward, or reduce width by the prefix length and attach the prefix to each returned line.

For terminal output, account for timestamps, log levels, indentation, and ANSI decoration outside this tool so the visible message stays within the desired boundary. In automated pipelines, store width as a project setting rather than scattering different values through scripts; this makes formatting changes reviewable and keeps generated files consistent. Test long technical tokens explicitly.

The algorithm never breaks a word, so a URL or generated identifier can exceed width, and callers that require hard limits should combine wrapping with a separate, explicit token-breaking policy. The capability performs no network calls and does not inspect the meaning of the text. Invalid requests are rejected before a result is produced.
