Convert any image (PNG, JPG, GIF, SVG, WebP) to a Base64 data URI for embedding in HTML, CSS, or JSON.
Convert any image into a Base64-encoded data URI ready to drop into your CSS, HTML, JSON payload, or design tool. Drag the image in, copy the result. No upload — encoding happens entirely in your browser.
Base64 data URIs let you embed an image directly in your stylesheet, HTML document, or JSON response without an extra HTTP request. This is useful for very small images (logos, spacers, icons) where the request overhead would outweigh the size savings, and for self-contained documents (email templates, single-file demos) where external assets aren't an option.
Drag-and-drop or file-picker upload.
Auto-detects MIME type and builds the correct data:image/...;base64, prefix.
Output preview with copy-ready CSS (background-image: url(data:...)) and HTML (<img src="data:...">) snippets.
Supports PNG, JPG, GIF, SVG, WebP, BMP, and ICO.
Works with files up to 10 MB, processed locally.
Use it for small, fixed assets that don't change between page loads — UI icons, gradient pixels, single-pixel transparencies. Avoid it for large hero images or anything that benefits from browser caching, since inline Base64 is downloaded fresh on every page load and inflates HTML/CSS file sizes by ~33%.
For SVG icons, prefer inline <svg> markup over Base64 — you get the same single-request benefit plus the ability to style with CSS. For email templates that disable external image loading by default, Base64 inline images bypass the block.
