Base64 converts binary data into text made of letters, digits, and a few symbols so it can be embedded in JSON, HTML, CSS, or data URIs. It is not encryption and does not protect sensitive data.
Any file type can be selected and encoded as a Base64 data URI, including images, fonts, PDFs, and ZIP archives.
The tool checks whether the decoded bytes can be read as text. If they can, it shows the text; if binary data is detected, it offers a file download.
