1. Paste or type your text
Start by pasting or typing your content into the left-hand input box on the main Pro Case Converter page. You can work with up to 25,000 characters at a time.
Instead of running your text through multiple tools, Pro Case Converter lets you type once and switch between case styles instantly. No extensions, no editor plugins, just a fast browser-based workflow.
Start by pasting or typing your content into the left-hand input box on the main Pro Case Converter page. You can work with up to 25,000 characters at a time.
Pick a mode such as sentence case, Title Case, Proper Case, UPPERCASE, lowercase, camelCase, or snake_case. The tool highlights the active mode so you always know which format is being applied.
As you type or paste new content, the right-hand output panel updates in real time based on the selected mode. You can switch modes at any point to see how your text looks in a different style.
Many users keep Pro Case Converter open in a browser tab while writing emails, blog posts, or documentation. It acts like a formatting sidekick for messy text.
If you are not sure which style reads best, simply toggle between modes instead of reformatting by hand. The content stays the same — only the casing changes.
