Text Converters
Text Conversion Tools
These tools transform text from one form to another — changing case, converting between number formats, encoding text for use in different systems, and more.
Case Converters
Text case is surprisingly important in web publishing, legal documents, and design. The tools here handle the most common conversions:
Capitalise first letters — capitalises the first letter of every word, useful for headings, titles, and names.
Title case converter — applies proper title case rules, which are more nuanced than simply capitalising every word. Articles, prepositions, and conjunctions below a certain length are lowercased unless they start the title.
Case converter — converts between UPPERCASE, lowercase, Title Case, Sentence case, and other formats in one tool.
Number Converters
Number to words — converts a numeric value (like 1,234,567) to its written English equivalent ("one million two hundred thirty-four thousand five hundred sixty-seven"). Useful for legal documents, cheques, and formal writing.
Text to binary — converts text characters to their binary (base 2) representation. Each character is shown as an 8-bit binary string. Useful for learning about how computers represent text internally.
Text to hexadecimal — converts text to its hexadecimal (base 16) byte representation. Useful for debugging, encoding work, and understanding character encodings.
Encoding Tools
Base64 encode — converts text or file content to its Base64 representation, ready to use in data URIs, HTTP headers, or JSON payloads.
Reverse words — reverses the order of words in a sentence or list. Sometimes useful for formatting, testing text-processing tools, or generating reversed text puzzles.
Text to slug — converts a phrase or title into a URL-friendly slug: lowercased, spaces replaced with hyphens, special characters removed. Useful for generating permalink slugs for blog posts, page titles, and product names.
Frequently Asked Questions
What is the difference between title case and sentence case?
Title case capitalises the first letter of most words (with exceptions for small words like "a", "the", "of"). Sentence case capitalises only the first word of the sentence and proper nouns — like a normal English sentence. Different style guides (APA, Chicago, AP) have different rules for which words to capitalise in titles.
What is a URL slug?
A slug is the part of a URL that identifies a specific page. For example, in example.com/blog/my-great-article, the slug is my-great-article. Slugs use only lowercase letters, digits, and hyphens — no spaces, punctuation, or special characters.
Why does text to binary produce such long output?
Each character is represented as 8 binary digits (one byte). A single letter "A" becomes "01000001". A short sentence of 20 characters produces 160 binary digits. This is how computers store and transmit all text internally.
