How to Use Image to Base64 Converter
Upload any image file (JPG, PNG, WebP, GIF, SVG) by dragging it into the dropzone or clicking to browse. The tool instantly generates both a data URL and a raw base64 string.
Output Formats
- Data URL — A complete data URI string (e.g.,
data:image/png;base64,...) ready to embed directly in HTML<img>tags or CSSurl()declarations. - Raw Base64 — The base64-encoded string without the data URL prefix, useful for API requests and programmatic use.
When to Use Base64 Images
Base64 encoding is useful for embedding small images directly in HTML/CSS to reduce HTTP requests, including images in emails, or storing image data in JSON or databases.
Frequently Asked Questions
Does base64 encoding increase file size?
Yes. Base64 encoding increases data size by approximately 33%. A 100 KB image becomes roughly 133 KB as base64. Use it for small images (icons, logos) rather than large photos.
Can I use the data URL directly in HTML?
Yes. Copy the data URL and paste it into an img src attribute: <img src="data:image/png;base64,...">. It works in all modern browsers.
What image formats are supported?
All browser-supported image formats: JPEG, PNG, WebP, GIF, SVG, BMP, and ICO.
Is my image uploaded to a server?
No. The conversion uses the FileReader API entirely in your browser. Your image never leaves your device.
