Question 1

What is Base64 encoding?

Accepted Answer

Base64 encodes binary data into ASCII text using 64 printable characters (A-Z, a-z, 0-9, +, /). It's used to embed binary data in text-based formats like JSON, XML, HTML, and email. The encoded output is roughly 33% larger than the input.

Question 2

How do I encode text to Base64?

Accepted Answer

Paste your text in the input field and click Encode. The tool converts each character to its UTF-8 bytes and then to Base64 representation. Click Copy to grab the result.

Question 3

When should I use Base64 encoding?

Accepted Answer

Common uses include: embedding small images in CSS/HTML (data URIs), sending binary data in JSON APIs, encoding file contents for upload, email attachments (MIME), and storing binary data in text-only databases.

Question 4

What's the difference between Base64 and Base64URL?

Accepted Answer

Standard Base64 uses + and / characters, which need escaping in URLs. Base64URL replaces these with - and _ and removes padding (=). JWTs use Base64URL encoding because tokens are often passed in URLs.
