Frequently asked questions
- What is Base64 encoding?
- Base64 is a way to represent binary data as ASCII text using 64 printable characters. It is commonly used to embed images in HTML/CSS, encode email attachments, and safely pass data in URLs.
- Is Base64 a form of encryption?
- No. Base64 is encoding, not encryption — it is easily reversible and provides no security. Do not use it to hide sensitive data.
- Does this tool send my data to a server?
- No. Base64 encoding and decoding runs entirely in your browser using JavaScript. No data is ever transmitted.
