Frequently Asked Questions
No. Base64 encoding and decoding run entirely in your browser. Nothing you enter is uploaded or stored.

Yes. You can encode an image into a Base64 data URI to embed it directly in HTML or CSS.
No. Base64 is an encoding, not encryption. It is easily reversible and provides no security — never use it to protect sensitive data.
