Embedding images without a server
When you're building a self-contained HTML file, an email template, or a component that needs to ship with its own assets, hosting images externally adds a dependency. Embedding them as Base64 removes it. The image becomes part of the file itself — no separate request, no broken link if the host goes down.
The trade-off is file size: Base64 is about 33% larger than the original binary. For small icons, logos, and decorative images it's usually worth it. For large photos, a hosted URL is still the better choice.
HTML and CSS output
After uploading an image, the tool gives you two ready-to-use snippets: an <img> tag with the Base64 data URI as the src, and a CSS background-image declaration. Copy whichever format you need. Drag and drop onto the tool or click to open the file picker — both work.
