Text & Encoding calculators
These tools count and transform text: word and character counts, reading time, case conversion, number to words, Base64, ASCII and Unicode code values, Morse code, and classical ciphers such as Caesar and Vigenère. A color harmony tool for building palettes also lives here.

Counting words, characters and reading time
Word counts look simple but depend on rules: whether hyphenated words count as one or two, how numbers and URLs are treated, and whether characters include spaces. Different tools can differ by a few words on the same text, so when a hard limit applies, use the counter the publisher or school specifies. The Word Count Calculator reports words, characters with and without spaces, sentences and paragraphs.
Reading time divides word count by a reading speed. Commonly cited estimates for adult silent reading fall around 200 to 250 words per minute, and speaking aloud is slower, often around 130 to 160. The Reading Time Calculator lets you set the speed to match your audience or a presentation.
Character codes and encodings
Every character is stored as a number. ASCII defines 128 codes covering English letters, digits and control characters; Unicode extends this to well over a hundred thousand characters across the world's scripts, and UTF-8 encodes them using one to four bytes each. The ASCII and Unicode Value Calculator shows the code point and bytes for any character, which helps when debugging garbled text.
Base64 represents binary data using 64 safe text characters, so it can travel in email, JSON or URLs. It turns every 3 bytes into 4 characters, making the data about a third larger. Morse code is an older encoding of letters as dots and dashes, still used in amateur radio and aviation navigation aids.
Classical ciphers and case styles
A Caesar cipher shifts every letter by the same amount, so there are only 25 possible keys and it can be broken by trying them all. The Vigenère cipher uses a keyword to vary the shift and resisted casual attack for centuries, but frequency analysis breaks it today. The Cipher Calculator includes a brute-force decoder that shows how quickly these fall, which makes them useful for teaching and puzzles rather than security.
Title case rules differ between style guides such as AP and Chicago, especially for short words like 'of' and 'with'. Check the guide your publication follows after using the Text Case Converter.
