Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that converts binary data into ASCII characters. It's commonly used in emails, data URLs, embedding images in HTML/CSS, and transmitting data over protocols that only support text.
Is Base64 encoding the same as encryption?
No. Base64 is an encoding scheme, not encryption. Anyone can decode Base64 data. It should never be used to protect sensitive information. Use proper encryption (like AES) for security.
Does this tool support file encoding?
This tool encodes and decodes text. For encoding files (images, PDFs) to Base64, you would need to first read the file as binary data.
