Text Tools – Online Utilities & Calculators
Professional browser-based typography and text tools to preview, test, compare, and export fonts and text in real time with client-side privacy.
Text and typography tools here run entirely in the browser: a font tester for comparing typefaces on real copy, character/word counters, case converters, and text cleanup utilities. No text you paste is transmitted anywhere.
Most used in Text Tools
Font Tester
Professional online typography tool with 120+ fonts across 8 categories to test, preview, compare side-by-side, and customize typography in real-time with responsive controls, color palettes, and CSS or image export.
Text Case Converter
Convert any text between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, and kebab-case in one click.
Remove Duplicate Lines
Strip duplicate lines from any list or text with optional case-insensitive comparison, whitespace trimming, and sorting.
Text Diff Checker
Compare two blocks of text line by line with highlighted additions and removals — perfect for comparing drafts, config files, or code.
URL Slug Generator
Convert any headline into a clean, lowercase, hyphen-separated URL slug with accent transliteration and optional stop-word removal.
Word & Character Counter
Live counts of words, characters (with and without spaces), lines, sentences, and paragraphs, plus an estimated reading time.
All Text Tools
Line Sorter
Sort any list of lines alphabetically, numerically, by length, in reverse, or shuffled randomly — with optional deduplication.
Find and Replace Text
Replace text across large bodies of content with literal or regular-expression matching, case control, and a live result preview.
Whitespace Remover & Text Cleaner
Clean pasted text in one pass: collapse multiple spaces, remove tabs, strip blank lines, join broken lines, and trim edges.
Reverse Text Generator
Flip text backwards character by character, reverse word order, or reverse the order of lines — instantly and locally.
Text to Binary Converter
Encode text into UTF-8 binary bytes and decode binary strings back into readable text, with full Unicode support.
Text to ASCII Codes Converter
Show the ASCII/Unicode code point of every character in decimal, hexadecimal, or binary — and convert code lists back into text.
Unicode Character Inspector
Break any text into its Unicode characters with U+ code points, UTF-8/UTF-16 encodings, and flags for invisible or confusable characters.
Testing fonts like a designer
A font preview is only meaningful on realistic content: paste the actual paragraph lengths, heading sizes, and character sets your product will use. Check the characters that break typefaces — tabular numbers in tables, accented characters, and mixed-language strings. Compare two fonts at the same rendered size, not the same nominal point size, because x-height differs between families.
Counting and transforming text
- Word counters here follow the whitespace convention; a URL or "state-of-the-art" counts as one word. Character counts distinguish with/without spaces because platform limits (tweets, meta descriptions) differ.
- Case converters are literal: Title Case capitalizes every word, Sentence case only the first — neither is smart about proper nouns, so review brand names after converting.
Common mistakes
- Judging a font at heading size only — body text at 14–16 px is where most typefaces differ.
- Pasting formatted text (from Word) with curly quotes and non-breaking spaces into a tool that counts them as distinct characters.
- Cleaning whitespace without checking code blocks, where indentation is meaningful.
