Q: What is sentence case?

Sentence case capitalizes only the first letter of each sentence. Other letters stay lowercase, matching normal paragraphs.

Q: Can I convert multiline text?

Yes. Paste multiple paragraphs or list lines; line breaks are preserved in the output so you can drop the result into docs, CMS fields, or spreadsheets.

Q: Is my text uploaded or stored?

No. Conversion runs in your browser with JavaScript. Text is not sent to UseBoldTools servers for this step.

Q: How do I copy the converted text?

Use the Copy Output button after choosing a case format. You can chain steps with “Use Output as Input” if you need multiple passes.

Uppercase, lowercase, title case, sentence case, and toggle case in one place—built for headlines, CMS fields, and messy paste-ins from PDFs or email. Pick a format after you paste; everything runs locally in your browser.

When a case converter beats manual fixing

Editors get ALL CAPS notes from stakeholders, spreadsheets export labels in the wrong casing, and PDF paste-ins often break sentence flow. A dedicated case tool fixes the whole block at once instead of hand-editing each word. Writers can normalize titles before publishing; developers can match constants or UI labels; students can fix drafts that were typed with caps lock on. Because this page keeps five explicit modes, you always know which rule you are applying—unlike a vague “format” button in a giant editor.

Toggle case is the odd one out: it flips each letter’s casing and is handy for quick visual checks or playful social copy, not production prose. For serious publishing, pair sentence or title case with a second pass from the extra spaces remover if the paste still carries double gaps from the source file.
