Frequently asked questions
What is Base64 used for?
Base64 represents binary or text data as plain ASCII characters, commonly for embedding images in CSS or HTML (data URLs), email attachments, and storing small blobs in JSON or config.
Is Base64 encryption?
No. Base64 is encoding, not encryption. It is easily reversible and provides no security, so never use it to protect secrets.
Is my input sent to a server?
No. Encoding and decoding happen locally in your browser, so your data stays private.
