Convert text to Base64 and back instantly with this online utility. Base64 encoding turns text into a safe ASCII format for use in data transmission, APIs, configuration files, and more — and you can decode back into readable text just as quickly. The tool works entirely in your browser for maximum privacy and speed.
Base64 is a binary-to-text encoding scheme that converts data into a set of 64 printable characters (A–Z, a–z, 0–9, +, /) with optional padding (`=`). It is commonly used to represent text, images, and files in a safe text format for systems that handle only text.
To encode text into Base64, enter your plain text and choose Encode. To decode a Base64 string back to plain text, paste the Base64 text and select Decode. The tool immediately shows the converted result.
Base64 encoding makes binary data safe to transmit or store in text-only systems like email, configuration files, web APIs, and data URIs. This online tool lets you quickly convert between formats without uploading data to servers — everything runs in your browser.
To get the most accurate output:
No — Base64 is an encoding format, not encryption. Anyone can decode Base64 string back to its original data. Use true encryption (e.g., AES) for sensitive data.
Yes — the tool supports plain text and most character sets when encoded correctly.
Yes — Base64 encoding and decoding tools are fully responsive and work on desktops and mobile browsers alike.
If the tool supports file upload, it can convert image or file content to Base64. Otherwise use a file-supporting encoder/decoder tool.
