Text transformer
Paste anything, tap an action, get it back transformed — case styles, developer formats, find & replace, sort, dedupe and more. All local, nothing leaves your browser.
One box, many transforms
The text transformer is an all-in-one scratchpad: switch text between UPPERCASE, lowercase, Title Case and Sentence case, convert to developer formats like camelCase, snake_case and kebab-case, find & replace (with optional regular expressions and case-insensitive matching), sort or reverse lines, remove duplicates, trim whitespace, Base64 encode/decode, and slugify — then copy or download the result.
Everything happens instantly in your browser, so it's fast and private. Press ⌘/Ctrl + Enter to copy the output. For dedicated single-purpose pages, see the case converters, alphabetize, or slugify tools.
Why one tool instead of many
Most of the time you don't know in advance which case you need — you're just cleaning up a heading, a variable name, or a pasted mess. The transformer keeps every option in one place so you can try UPPERCASE, then Title Case, then camelCase on the same text without hopping between pages. It's the fastest way to reshape a single string.
When to use a dedicated tool
For repeated, single-purpose work the focused converters go deeper: the title case, sentence case and developer case pages each explain their format and its conventions. Like everything here, the transform runs entirely on your device.
