Image to Base64 Encoder
Upload any image — PNG, JPG, GIF, WebP, SVG — and get an instantly usable Base64-encoded data URL. The tool shows the full data:image/... string ready to paste into HTML, CSS, or JSON.
Base64 encoding embeds images directly in code, eliminating extra HTTP requests. This is especially useful for small icons, logos, and UI elements where an inline embed is faster than a separate file request.
Everything runs in your browser using the FileReader API. Your image is never uploaded to any server — it's converted locally and stays on your device.

Frequently asked questions
What image formats are supported?▼
Any format your browser supports: PNG, JPEG, GIF, WebP, SVG, BMP, ICO, and more. The output data URL preserves the original MIME type (e.g. data:image/png;base64,...).
Is there a file size limit?▼
No hard limit, but very large images (10MB+) may cause your browser tab to slow down because the Base64 string is roughly 33% larger than the original file. For most web use cases, images under 1MB work best as Base64.
When should I use Base64 images vs regular image files?▼
Base64 is best for small images (icons, logos under ~10KB) where eliminating an HTTP request improves load time. For larger images, regular files with proper caching are more efficient — Base64 increases the HTML/CSS file size and can't be cached independently.
Is my image uploaded to a server?▼
No. The conversion runs entirely in your browser using the JavaScript FileReader API. Your image never leaves your device.
