Base64 Encoder/Decoder

Our Base64 Encoder/Decoder tool converts text and files between regular text and Base64 format. Base64 encoding is essential for transmitting binary data over text-only protocols like email or HTTP. This free online tool supports both encoding (converting text to Base64) and decoding (converting Base64 back to text). Base64 encoding works by converting binary data into a ASCII string format, making it safe for transmission through systems that only support text. This is particularly useful for embedding images in HTML/CSS, sending file attachments in JSON APIs, or storing binary data in databases that only accept text. Our tool includes URL-safe encoding options that replace + with - and / with _, making the encoded strings safe for use in URLs and filenames. You can also upload files directly for encoding, which is perfect for converting images to data URLs for web development. The tool provides detailed statistics including input/output size comparison and character counts. All processing happens locally in your browser, ensuring your sensitive data never leaves your computer. Whether you're a developer working with APIs, a designer embedding images, or just need to encode/decode Base64 data, this tool provides a fast, secure, and reliable solution.
