Key Features
FAQs
What does Base64 Encoder / Decoder do?
It converts plain text into Base64-encoded strings and decodes Base64 strings back into readable text. It also converts images into Base64 data URIs that you can embed directly in HTML, CSS, or JSON.
Is my data safe when using this tool?
Yes. All encoding and decoding happens 100% in your browser. No text, images, or Base64 data is ever sent to a server or stored anywhere.
What image formats are supported?
The tool supports PNG, JPG/JPEG, GIF, SVG, and WebP image formats. You can drag-and-drop or use the file picker to select an image.
What is a Base64 data URI?
A data URI is a string format that embeds file data directly in code. For example, 'data:image/png;base64,...' lets you embed an image in HTML or CSS without needing a separate file. This tool generates these URIs automatically.
Does it handle special characters and Unicode?
Yes. The tool fully supports UTF-8 encoding, so it correctly handles special characters, emojis, and text in any language.
