Base64 Encoder

Usage Guide

Base64 turns binary data into visible text, which is useful when small images, files, certificates, or snippets need to pass through text-only systems. Enter plain text to encode it, paste Base64 to decode it, or convert an image into a Data URL for HTML, CSS, or temporary documents. Remember that Base64 is not encryption: anyone with the string can decode it. It solves transport and embedding problems, not confidentiality. Large files also grow by roughly one third, which can slow pages, APIs, and logs.

Examples

• Convert a tiny SVG or icon into a Data URL for a quick CSS background prototype.
• Decode an API field to confirm whether the actual payload is JSON, text, or a binary marker.
• Encode a short config snippet before placing it in an environment variable that dislikes special characters.

FAQ

• Is Base64 secure? No. It is encoding, not encryption.
• Why does decoded text look broken? The original bytes may not be UTF-8 text, or the string may be truncated or escaped.
• Should every image be Base64? No. Use it for small inline assets; use normal file URLs for larger images.
