What is the difference between Base64 and URL-safe Base64?

Standard Base64 uses + and / characters, which are special in URLs. URL-safe Base64 replaces them with - and _ so the encoded string can be used directly in URLs without percent-encoding.

Can I encode binary files, not just text?

Yes. Use File mode to upload any file (image, PDF, binary) and get its Base64 representation, which you can embed in HTML, CSS data URIs, or JSON payloads.

Does Base64 compress or encrypt data?

Neither. Base64 only encodes binary to ASCII text — it increases size by about 33% and provides no security. For encryption, use AES-256 or similar algorithms.

What is Base64 Encoder?

Base64 is a binary-to-text encoding scheme that represents binary data using 64 printable ASCII characters. It is widely used to embed binary data — images, files, certificates — into text formats like JSON, XML, HTML, and email headers. DailyDevTools' Base64 Encoder/Decoder converts text and binary data to and from Base64 instantly in your browser, supporting both standard and URL-safe Base64 variants with no server involved.

How to use Base64 Encoder

1Type or paste your text in the input field, or switch to File mode to upload any binary file
2Click Encode to convert your input to Base64, or paste an existing Base64 string and click Decode
3Toggle URL-safe mode to use - and _ instead of + and / for safe use in URLs and filenames
4Click Copy to copy the result directly to your clipboard
