Encode a File to Base64
About This Tool
The Zaberz Base64 Encoder & Decoder converts text or files into Base64 format and back, correctly handling Unicode characters like emojis and non-Latin scripts. It also supports URL-safe encoding for use in links and tokens, and can encode entire files — such as images — into a Base64 string ready to embed directly in HTML or CSS. All conversion happens locally in your browser.
How to Use
- 1 Type or paste text, then click Encode or Decode.
- 2 For files, upload one below to get its Base64 output.
- 3 Copy the result or download it as a .txt file.
