Convert any image to Base64 instantly in your browser. Drag and drop your file, preview it, and copy the Base64 string or data URI for embedding in CSS, HTML, or JSON.
Base64 encoding allows you to embed images directly into CSS, HTML, or JSON without making additional HTTP requests. This technique is especially useful for small icons, logos, and UI elements where reducing network round-trips improves page load performance.
The data URI format includes the MIME type (like image/png) so browsers can render the image correctly. Our tool detects the image type automatically and generates a ready-to-use data URI you can paste directly into your code.
We support all common web image formats including PNG, JPEG, GIF, WebP, BMP, and ICO. The tool automatically detects the format.
You can convert images up to 50MB. For larger files, we use Web Workers to process in the background without freezing your browser.
No. All processing happens locally in your browser. Your images never leave your device.
