Frequently asked questions
What does an uppercase converter do?
It changes every small letter in your text into a capital letter. Numbers, punctuation, spacing and line breaks are kept as they are.
Why keep web addresses unchanged?
Parts of a web address can depend on case, so changing them may break the link. Email addresses are usually fine either way, but leaving them alone keeps them looking normal.
What happens to the German letter ß?
By default ß becomes SS, the standard capital spelling. Untick the option to keep ß as it is.
Is writing in all capitals considered shouting?
Online, long passages in capitals often read as shouting and are harder to read. Use capitals for short headings, labels and codes, and sentence case for normal text.
Does it work for other languages?
Yes, for languages with capital letters, such as French, Spanish, German, Greek and Russian. Languages without case, such as Urdu, Arabic and Chinese, are left unchanged.
Can I go back to normal text?
Use the Sentence Case Converter to turn capitals back into normal sentences, or the Lowercase Converter for all small letters.
Are my line breaks kept?
Yes. Only letters change, so lists and paragraphs keep their layout.
Should I write my name in capitals on official forms?
Many forms, such as visa and bank forms, ask for block capitals so handwriting and scanners read names correctly. Follow the instructions on the form, and keep spaces and hyphens in names as they are.
Does uppercase text affect search engines?
Search engines treat capitals and small letters the same, but headings and titles in capitals can look like shouting in search results, which may reduce clicks.
Is the text I paste kept private?
Yes. The conversion runs inside your browser, so your text is never uploaded or stored anywhere.
How this tool works. These text tools run entirely in your browser with plain JavaScript, so the text you paste never leaves your device and results update as you type. Each tool is tested with real text such as copied PDFs, emails, code, lists, emojis and non-English scripts before it goes live.
