🔐 Base64 Text Encoder
Type or paste your text and instantly encode it to Base64.
What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It's commonly used to encode data that may be corrupted during transfer, such as email attachments, images in HTML or CSS (data URIs), or when storing binary blobs in JSON.
Every 3 bytes of binary data become 4 printable ASCII characters from the set A-Z, a-z, 0-9, +, and /. The process is fully reversible — decoding brings back the original data.
When Should You Use This Tool?
- Encoding email attachments (MIME).
- Embedding images directly in HTML/CSS using data URIs.
- Storing binary data in JSON or text-based databases.
- URL-safe data encoding (using Base64URL variant).
Is Base64 Encryption?
No, Base64 is not encryption — it provides no security. It's simply a way to represent data in a text-friendly format that avoids character set issues. Anyone can decode it instantly.
Use this free tool anytime you need a quick, client‑side Base64 conversion without sending your data to any server.
