Base64 Encoder / Decoder

Safely encode text, extract files from Base64 Data URIs, and preview decoded images instantly. Fully optimized for UTF-8 (Urdu/Arabic/Emojis).

Advanced Base64 Encoding & Image Extraction

Base64 is an encoding algorithm that transforms any binary data (like images, audio, or complex text) into a safe string consisting of 64 printable ASCII characters. It is heavily used in web development for embedding assets safely over networks.

• Smart Image Decoding: If you paste a Base64 Data URI (like data:image/png;base64,...) into our Decoder, the tool automatically recognizes it, provides a live visual preview, and allows you to download the original image or file directly to your device.
• UTF-8 Support (Urdu, Arabic, Emojis): The standard JavaScript btoa() function fails when encoding multi-byte characters like Urdu text or Emojis. Our tool uses a highly optimized encodeURIComponent escaping sequence to safely handle all global character sets.
• 100% Client-Side Privacy: Whether you are extracting a private image or decoding an API token, everything happens inside your browser. Your data never touches our servers.
