Frequently Asked Questions
What is Base64?
Base64 is an encoding system that converts binary data into ASCII text strings. It is commonly used to transfer data on media that only support text, such as email, URLs or JSON. It is not an encryption method, but simply an encoding format.
Is it safe to use this tool online?
Yes, absolutely. The entire conversion process happens locally in your browser using JavaScript. No data is sent to our servers or third parties. Your content remains private and secure.
What is the difference between encoding and encryption?
Base64 encoding transforms data into a different format but is easily reversible by anyone. Encryption, on the other hand, protects data with a secret key and only those with the key can decrypt it. Base64 is NOT secure for protecting sensitive information.
When should I use Base64?
Base64 is useful for: embedding images in HTML/CSS (data URIs), sending binary data in JSON or XML, encoding credentials in HTTP Basic Authentication, transferring files via email, and in general when you need to represent binary data as text.
