Frequently Asked Questions
What is Base64 encoding used for?
Base64 is used to encode binary data (images, files) as ASCII text for safe transmission in emails, APIs, and HTML data URIs.
How is Base64 different from encryption?
Base64 is not encryption — it is just encoding. Anyone can decode a Base64 string without a key. Do not use it to protect sensitive data.
Can I encode images to Base64?
Yes. Upload an image file and the tool will generate a data URI Base64 string you can embed directly in HTML or CSS.
