Frequently Asked Questions

Does this tool save my text?

**Absolutely not.** The conversion happens entirely in your computer's Random Access Memory (RAM). Once you close or refresh the tab, your text is gone forever. We have no "Save" button on our server side because we don't have a database for your text.

Is there a word limit?

**No.** Unlike cloud-based tools that limit you to 1,000 words, you can paste as much text as your browser can handle. Whether it's a tweet or a novel chapter, it works.

Does it handle special characters?

**Yes.** It preserves punctuation, emojis, numbers, and symbols. It only alters the casing of alphabetical characters.

Can I convert PDF text to lowercase?

Yes. First, copy the text from your PDF. Then paste it here. PDFs often have messed up formatting (ligatures, etc.), which our tool can help standardize if you re-type into clean text.
