How to convert text case

  1. Step 1

    Enter or upload text

    Type, paste, or upload a .txt file. Character, word and line counts update as you go.

  2. Step 2

    Choose a conversion

    Pick UPPERCASE, Title Case, Alternating Case, Replace Spaces, Count Text and more.

  3. Step 3

    Tune formatting options

    Preserve line breaks, trim extra spaces, remove empty lines, or preview changes in real time.

  4. Step 4

    Copy or download

    Edit the converted output if needed, then copy it or download converted.txt.

Real text case conversion — entirely in your browser

OneFileKit converts case with real Unicode-aware transforms. Whitespace, punctuation, hyphens and apostrophes are handled carefully so Title Case and Sentence case stay readable.

Count Text reports characters, words, lines and paragraphs without changing your source. Analytics only record aggregate events such as conversion type and size range — never your text.

Uploads stay local: files are read in the browser, UTF-8 BOM is stripped when present, and nothing is executed or stored on our servers for normal use.

Frequently asked questions

Is my text uploaded?
No. Conversion runs locally in your browser. Your text stays in your browser and is not sent to the server for normal use.
Which files can I upload?
Plain text files with .txt or .text extensions (UTF-8). Files are validated for size and character limits before loading.
Does Count Text change my input?
No. Count Text leaves your source text unchanged and shows character, word, line and paragraph statistics in the output panel.
Do you store or log my text?
No. Analytics only track aggregate events (conversion type, size range, upload/download). We never store the actual user text.
