What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data. This ensures that the data remains intact without modification during transport.

Common Use Cases for Base64

Base64 is frequently used in web development for embedding image files directly into CSS or HTML as Data URIs, encoding credentials for Basic HTTP Authentication, and safely transmitting cryptographic keys or JSON Web Tokens (JWTs) across the internet.

Why use our Base64 Tool?

Often, you need to encode or decode sensitive information (like passwords, API keys, or private tokens). Using server-side online tools puts your private data at risk. DevvTools performs Base64 encoding and decoding 100% locally in your browser. We do not track, log, or transmit your inputs, giving you absolute privacy and instant results.
