Word & character counter
Count words and characters as you type. Useful for articles, assignments, captions, and page descriptions.
Words are Unicode letter or number groups. Characters count Unicode code points, including punctuation. Reading time is an estimate at 200 words per minute; languages without word spacing may be undercounted.
Text case converter
Change text to uppercase, lowercase, title case, or sentence case.
Title case capitalises each word; it does not apply a publication style guide. Sentence case may require manual corrections for names and abbreviations.
URL slug generator
Turn a heading into a clean, hyphenated URL segment. Choose Unicode or ASCII output.
This generates one URL segment, not a complete URL. ASCII mode removes unsupported characters and is not full transliteration. Changing a published URL may require a redirect.
UTM link builder
Add consistent campaign labels to a link so your analytics setup can identify the visit source.
Only HTTP and HTTPS destinations are accepted. Existing UTM parameters are replaced; other parameters and fragments are preserved. This tool does not install analytics. Avoid putting personal data in campaign labels.
JSON formatter & validator
Format or minify JSON and check for syntax errors.
Validation checks JSON syntax, not a schema. Formatting uses JavaScript parsing: very large numbers can lose precision and duplicate object keys collapse to the final value. Do not use it for data that requires exact numeric preservation.
URL encoder / decoder
Encode a parameter value or a complete URL, or decode percent-encoded text.
Parameter mode encodes URL separators; complete-URL mode preserves them. Decoding uses the matching function and leaves plus signs unchanged. Encoding is not encryption.
