The Base64 Encoder & Decoder converts text and binary data to and from Base64 encoding, which is a standard method for representing binary content as ASCII text. Developers use Base64 daily for embedding images in CSS, encoding email attachments, passing data in URLs, and working with APIs that require Base64-encoded payloads.
Paste any text and instantly see the Base64-encoded output, or paste a Base64 string to decode it back to its original form. The tool also handles file-to-Base64 conversion, letting you drag and drop images, PDFs, or other files to get their Base64 representation for embedding in HTML or JSON.
This is a bread-and-butter developer utility that saves you from writing throwaway scripts or searching through terminal commands every time you need a quick Base64 conversion. Everything runs client-side in your browser, so your data never leaves your machine.
