Case Converter
Eleven naming conventions, applied correctly to acronyms and mixed input.
Word and Character Counter
Live counts, plus the length limits that will actually bite you.
Remove Duplicate Lines
Deduplicate thousands of lines in one pass, order preserved.
Sort Lines
Including natural order, which is what you wanted when file10 sorted before file2.
URL Slug Generator
A readable, stable, lowercase slug — with the words that do not belong in a URL removed.
Lorem Ipsum Generator
Placeholder text you can regenerate byte-for-byte, for mockups that do not shift between reviews.
Word Frequency Counter
Which words you actually overuse — as a ranked table, not a guess.
Extract Emails, URLs and Numbers
Pull the structured values out of prose or pasted logs — deduplicated, in order.
Why these run locally
Every tool on this page processes its input in the browser tab. For this category that matters because the inputs are frequently sensitive: digests of passwords and keys, authentication tokens, spreadsheet exports containing personal data, photographs of identity documents. None of that is transmitted, and the tools keep working if you disconnect from the network after the page loads.
