When should you use image Base64?
Base64 is useful for embedding small assets directly in HTML, CSS, or JSON payloads. It can reduce extra HTTP requests in specific cases, but larger images are still better delivered as normal files.
Privacy-first encoding for development
Your image never leaves your browser during encoding. For format conversion and file size reduction, use Image Converter or Image Compressor . To check hidden EXIF and GPS fields before sharing, use Image Metadata Viewer or clean metadata directly with Image EXIF Remover.
When Base64 helps and when it hurts
Good use cases
- Small icons embedded in HTML email templates.
- Inline assets in generated JSON payloads.
- Quick prototypes without static file hosting setup.
Avoid for
- Large hero images on production landing pages.
- Assets that should be cached independently by CDN.
- Situations where HTML/CSS payload size is already high.
Practical implementation examples
HTML inline image
<img src="data:image/webp;base64,AAA..." alt="Inline icon" />
JSON payload field
{
"mimeType": "image/png",
"base64": "iVBORw0KGgoAAA..."
}Frequently Asked Questions
What is the difference between Data URL and raw Base64?
Data URL includes a prefix such as `data:image/png;base64,` and can be pasted directly into HTML image sources. Raw Base64 only contains the encoded payload.
Does Base64 make image files smaller?
No. Base64 text is typically larger than the original binary file. Use it for convenience in embedding, not for compression.
Is this image encoding done on the server?
No. Encoding is fully client-side, so your file remains local to your device.
