Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.
Switch text between UPPER CASE, lower case, Title Case, Sentence case, and the programmer cases — camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case — plus alternating and inverse for fun. A live character, word and line count sits under the input.
Everything converts in your browser. To sort, de-duplicate or trim a list of lines, use the Text Cleaner.
Title Case capitalises the first letter of every word; Sentence case capitalises only the first word of each sentence. Both are one click here.
Yes — camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case, converting cleanly between any of them.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
InfyTool is built by the same team as these free libraries.
