About lowercase
Converting text to lowercase reformats your words without changing their meaning — handy for headings, code, data and tidying up pasted text.
Everything runs locally in your browser, with no upload, no limit and no sign-up, and you can chain conversions on the same text.
Lowercase makes every letter small, which is the safest way to normalise text before a case-insensitive comparison so that "Email", "email" and "EMAIL" all match. It's the conventional form for URL paths, email addresses, tags and hashtags, where mixed capitals can confuse links, deduplication or lookups. Reach for it when you want one canonical version of a word and don't need to preserve the original capitalisation.
Frequently asked questions
How do I convert text to lowercase?
Paste your text into the box and press the lowercase button. The text is converted instantly and you can copy it — all in your browser.
Is my text uploaded anywhere?
No. The conversion happens entirely in your browser, so your text never leaves your device and nothing is stored online.
Can I switch to another case?
Yes. The other options (UPPERCASE, lowercase, Title Case, Sentence case and more) are right there, so you can transform the same text again.
Is there a limit on how much text I can convert?
No. You can convert as much text as you like — it runs locally and instantly, with no sign-up.
Does lowercasing affect the part before the @ in an email address?
It will lowercase the whole address, which is fine for the domain (always case-insensitive), but technically the local part before the @ can be case-sensitive — in practice almost every provider treats it as lowercase, so it's safe for normalising and deduplicating addresses.
