Unicode normalize

Client

NFC, NFD, NFKC, and NFKD in one local tool.

About Unicode normalization

Apply NFC, NFD, NFKC, or NFKD normalization to text—code point counts and copy output, browser-only. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.

How to use this page

Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.

Choose a Unicode normalization form. To strip accents only, use Remove accents.

Input 4 code points → output 4 code points (NFC)

  • Line ending converter — Count LF, CRLF, and CR; normalize to one EOL style; optional UTF-8 BOM strip—local only, Git-friendly. for the next text or markup step in your edit loop.

Common use cases

  • Normalize user input before hashing or database unique indexes.
  • Compare NFC vs NFD for accented characters in i18n QA.
  • Apply NFKC to fold compatibility characters before search indexing.

Common mistakes to avoid

  • Using NFKC for all storage

    NFKC can change meaning (e.g. ligatures)—pick the form your spec requires.

  • Confusing with accent removal

    Use Remove accents when you only need ASCII-friendly slugs.

FAQ

Which form should I use?

NFC is common for storage; NFD helps when stripping combining marks; NFKC/NFKD fold compatibility glyphs.

Is text uploaded?

No. Normalization uses String.normalize in your browser.
