Frequently asked questions
What is Base64 encoding used for?+
Base64 converts binary or text data into an ASCII-safe string, commonly used for embedding images in CSS or HTML, email attachments, and API tokens.
Does this tool handle special characters and emoji?+
Yes, the encoder correctly handles UTF-8 text, including accented characters and emoji, not just plain ASCII.
Can I decode Base64 that contains binary data?+
The tool is optimized for text. For binary files like images, decoded output may not display correctly as text but the underlying conversion is still accurate.
Is Base64 the same as encryption?+
No. Base64 is an encoding, not encryption. It provides no confidentiality and can be reversed by anyone instantly.
