Case Modify is a free online text toolkit: case converters (uppercase, lowercase, title case, sentence case), Unicode stylers, code formatters, encoders, random generators, and unit converters. Every tool runs in your browser—no account required.
Students fix essay capitalization, bloggers format headlines, developers prettify JSON and test regex, marketers build UTM links, and teams share quick utilities without installing desktop software.
For standard tools, your text and values stay on your device after the page loads. That makes Case Modify practical for drafts, proprietary snippets, and customer data samples you do not want uploaded to a remote formatter.
