Frequently asked questions
What is Base64 encoding actually used for?
It converts binary data into plain ASCII text so it can be safely embedded somewhere that only supports text — email attachments, data URLs in CSS/HTML, API payloads, and config files.
Is Base64 a form of encryption?
No. Base64 is a reversible text encoding, not encryption — anyone can decode it instantly. Don't use it to protect sensitive data.
Can I encode images or files with this tool?
This tool encodes and decodes plain text. To convert an image file to Base64, use the dedicated Image to Base64 tool instead.
