About the Base64 File Encoder
Upload a file and generate Base64 output with file size and MIME details. This can simplify testing APIs or embedding small assets in code examples.
Common uses
- Encode small files for API tests.
- Create data URIs for images or assets.
- Inspect file MIME and encoded size.
Tips for Using Base64 File Encoder
Base64 increases size by roughly one third, so avoid embedding large files when a normal file upload or CDN asset is more appropriate.
