Case Converter — frequently asked questions

What is Title Case vs Capitalize Each Word?+

Capitalize Each Word capitalises every word. Title Case follows style rules — small words like 'and', 'the', 'of' stay lowercase unless they are first or last.

Does camelCase / snake_case strip punctuation?+

Yes — programmer cases remove spaces and punctuation and join the words, since that is how identifiers are written.

Can I undo a conversion?+

Your original text stays in the top box, so you can re-run a different case at any time.

Adakah anda memuat naik fail saya ke pelayan?+

Tidak — setiap alat di sini memproses fail anda sepenuhnya pada peranti anda, dan tiada apa dimuat naik ke pelayan. Satu-satunya pengecualian ialah alat AI, yang menghantar teks yang diekstrak (bukan fail) ke Claude untuk melakukan kerjanya.

Adakah terdapat had saiz fail?+

Kami tidak mengenakan had buatan, tetapi kerana pemprosesan berlaku dalam pelayar anda, fail yang sangat besar (500+ MB atau 1,000+ muka surat) dihadkan oleh memori peranti anda, bukan oleh kami.
