Case Converter Online

Updated 2026-07-09

Convert text between camelCase, PascalCase, snake_case, kebab-case, UPPER CASE, lower case, and Title Case instantly, right in your browser. Paste any string and SnapTools rewrites it in the casing you pick as you type, then lets you copy or download the result. Nothing is uploaded — all conversion runs locally, so it is safe for code, identifiers, and private text.

Switching naming conventions by hand is slow and error-prone across many words. The Case Converter detects word boundaries automatically and rebuilds your text in one step, whether you are renaming variables, normalizing column names, or formatting headings.

// how to use

  1. 1 Paste or type your text into the input panel on the left — conversion runs as you type.
  2. 2 Open Settings to pick the target case (camelCase, PascalCase, snake_case, kebab-case, UPPER CASE, lower case, or Title Case).
  3. 3 Read the converted text on the right, then click Copy or Download.

camelCase, PascalCase, snake_case, kebab-case, UPPER CASE, lower case, and Title Case. It detects word boundaries from spaces, underscores, hyphens, and capital letters.
Yes. The converter splits the input into words first — whether they are separated by spaces, underscores, hyphens, or capitalization — then rebuilds them in the target case.
No. Conversion happens in your browser — nothing is uploaded, so it is safe for private notes, code, and identifiers.
This tool reformats the casing of whole words across your text; Find & Replace swaps specific strings for others. Use Find & Replace when you need targeted substitutions rather than case changes.
Numbers stay attached to their surrounding word, and acronyms are treated as regular words — so "parseHTML5" becomes "parse_html5" in snake_case. Review the output if you need a specific acronym style.
