Image to Base64

Convert an image to Base64 online in seconds. Paste, upload, or drag-and-drop a picture to get a clean image Base64 string (a text representation of the file) you can use in HTML, CSS, JSON, or APIs. This image to Base64 converter supports PNG, JPG/JPEG, GIF, WebP, SVG, ICO, and BMP—perfect for convert image file to Base64 string, JPG to Base64 online, PNG to Base64 encoder, and building Base64 data URLs for the web.

What is “Image to Base64” (and why use a Base64 image encoder)?

Image to Base64 encoding turns binary pixels into a text-safe string using the Base64 alphabet. The result often appears inside a data:image/*;base64,... URL, so you can embed an asset inline without hosting a separate file. If you’ve searched for “encode image as Base64 data URL”, “image file to Base64 string converter”, or “online PNG/JPG to Base64 tool”, this is exactly that workflow.

How to use the Image → Base64 converter

1. Upload or drop an image (PNG, JPG, GIF, WebP, SVG, ICO, BMP) or paste a file from clipboard.
2. Choose options:
   • Output format: raw Base64 or full data URL (data:image/png;base64,...).
   • Line wrap: no wrap for APIs; 76-char wrap for MIME emails.
   • URL-safe Base64 (replace +// with -/_) for tokens and query strings.
3. Click Encode to generate the Base64 image string, then copy or download the result.

When should you use an online image to Base64 tool?

• Inline assets: Embed icons and small sprites via Base64 image data URL in HTML/CSS.
• Email/MIME: Some templating flows prefer JPG to Base64 strings with 76-char wrapping.
• APIs & JSON: Send images through text-only channels (image to Base64 for REST/GraphQL).
• No hosting: Quick prototypes where PNG to Base64 in a single file is convenient.

Who is this for?

• Front-end developers needing a fast JPG/PNG to Base64 converter for data URIs.
• Email & marketing teams embedding Base64 images in HTML newsletters.
• Designers & QA sharing assets as Base64 strings for bug reports and handoffs.
• Automation & DevOps piping screenshots through image to Base64 API workflows.

Best practices & caveats

• Overhead: Base64 adds ~33% to size. Great for small assets; large images should stay as files.
• Caching: Data URLs are bundled with the page; separate files can be cached by the browser/CDN.
• Correct MIME: Use the right prefix (image/png, image/jpeg, image/svg+xml) or previews may fail.
• URL-safe: For query strings, pick the URL-safe Base64 variant and consider stripping = padding.

Troubleshooting

“Image won’t display”

Verify the MIME prefix matches the actual format (e.g., JPEG vs PNG) and ensure the Base64 string isn’t wrapped or truncated.

“Why is the file so large?”

Base64 inflates size by ~33%. For performance, use external files, compression, or WebP/AVIF before converting image to Base64.
