Frequently Asked Questions

What is Base64 encoding used for?

Base64 encoding converts binary data into ASCII text representation. It is widely used in web development for embedding inline images in CSS/HTML and transmitting binary payloads over text-based protocols.

Is Base64 encoding a form of encryption?

No. Base64 is an encoding format, not encryption. Anyone can decode Base64 data. If you need confidential encryption, use our AES-256 File Encryptor tool.

Are my images or text uploaded anywhere?

No. All text string and image file reader conversions occur locally in your browser DOM.
