Format, wrap, and align plain text, email drafts, markdown documents, and source code blocks with real-time column precision. The Universal Text Wrap Tool by RiazHub empowers developers, editors, and technical writers to enforce strict RFC 2822/5322 72-character email standards, 80-column PEP 8 and terminal boundaries, or custom line limits without breaking words mid-sentence. Features include word-boundary safe slicing, forced character splitting, a dual-direction paragraph unwrapper to merge fragmented lines, custom line delimiters (\n, \r\n, <br>), hanging comment prefixes (// , > ), and a live visual character ruler with column guide lines. Powered by an instant, 100% in-browser client-side engine ensuring complete confidentiality and zero server data transmission for sensitive emails, codebases, and private documentation.

Wrapping Strategy

Hard Wrap (Word-Boundary Safe) Breaks lines at spaces/hyphens before column limit without cutting words.

Force Strict Wrap (Mid-Word Break) Splits strictly at exact character count, slicing words if necessary.

Unwrap / Join Lines Merges fragmented lines back into clean, cohesive paragraphs.

Wrap with Hanging Indent / Prefix Applies prefixes (e.g., //, >, tabs) to wrapped subsequent lines.

📖 Why 72-Character Wrapping Remains the RFC Email Standard ▼

Under RFC 2822 and RFC 5322 (Internet Message Format), plain text emails are recommended to have lines no longer than 78 characters, with 72 characters being the universally adopted industry norm.

This standard ensures that when an email message is quoted and replies are prepended with reply markers (e.g., > or >> ), the lines will not wrap awkwardly or cause jagged stair-stepping formatting on terminal-based email clients, mailing lists, and patch submission systems like the Linux Kernel Mailing List (LKML).

⚡ Hard Wrap vs. Soft Wrap: What Is the Difference? ▼

Soft Wrap: A purely visual rendering trick performed by text editors, web browsers, and word processors. No newline characters are actually inserted into the underlying data stream. If you copy the text into another program, it remains one giant, unbroken single line.

Hard Wrap: Explicit newline characters (\n or \r\n) are permanently injected at specific column boundaries. This guarantees that your lines break at exact character widths across any terminal, source code repository, plain text viewer, or embedded printer.

🖥️ The History & Value of 80-Column Line Limits in Code & Terminals ▼

The ubiquitous 80-column limit traces its history back to the 1928 IBM punch card format, which featured 80 columns of punched data. This standard was adopted by classic CRT computer displays such as the DEC VT100 terminal.

In modern software engineering, coding conventions like Python's PEP 8 and standard C/C++ style guidelines enforce 79 or 80 column limits. This permits developers to view two to three code files side-by-side on wide monitors without horizontal scrolling, and dramatically improves reading comprehension.

🔒 100% Privacy Guarantee: Zero Server Transmission ▼

This tool operates with complete client-side autonomy. Every line computation, regex parsing step, and file generation routine is executed in your web browser's local JavaScript memory.

Zero data is sent to RiazHub or any third-party server. You can safely format confidential legal contracts, proprietary source code, private cryptographic keys, and sensitive correspondence without privacy risk.
