Why would I need to encode to Base64?

Common uses: embedding images in HTML/CSS, sending binary data in JSON/XML, encoding email attachments, and storing binary in text databases.

Can I encode images to Base64?

Yes, upload an image file to get its Base64 representation. This can be used in data URIs to embed images directly in HTML or CSS.

Does Base64 provide encryption?

No, Base64 is encoding, not encryption. Anyone can decode Base64 text. For security, use actual encryption methods.

Why does Base64 make files larger?

Base64 encoding increases size by about 33%. Three bytes of data become four Base64 characters, plus padding if needed.

URL-safe Base64 replaces + with - and / with _ to avoid URL encoding issues. Useful for tokens and query parameters.
