Image to Base64 Features
Fast & Secure Encoding
Convert any image to Base64 string instantly with privacy-first client-side processing.
Multiple Formats
Supports JPG, PNG, GIF, WEBP, BMP, SVG and more. Also handles PDF first page extraction.
Data URI Ready
Get ready-to-use Data URIs (e.g., "data:image/png;base64,...") for embedding in HTML/CSS.
Client-Side Processing
All conversions happen in your browser. Images never leave your device â 100% private.
What is Base64 and why encode images?
Base64 encoding converts binary image data into ASCII text, allowing you to embed images directly in HTML, CSS, JavaScript, or JSON without separate file requests. It's perfect for:
- â Data URIs in web pages (img src, CSS backgrounds)
- â JSON APIs (sending images as strings)
- â Email attachments (plain text)
- â Database storage
Our tool generates both the raw Base64 and the ready-to-use
Data URI.
Frequently Asked Questions
What is Image to Base64 converter? +
It's a tool that encodes image files (JPG, PNG, GIF, etc.) into a Base64 string, which represents the image data in ASCII format. This string can be used as a Data URI to embed images directly in HTML, CSS, or JavaScript.
Is it safe to upload my images? +
Yes, 100% safe. All processing is done locally in your browser using JavaScript. Your images are never uploaded to any server, ensuring complete privacy.
What is a Data URI? +
A Data URI is a Base64 encoded string prefixed with the MIME type (e.g., `data:image/png;base64,`). It allows you to embed the image directly in web pages without an external file. Our tool provides both the raw Base64 and the complete Data URI.
What image formats are supported? +
We support all common formats: JPG, PNG, GIF, WEBP, BMP, SVG, and even the first page of PDF files. The tool reads the file as binary data and converts it to Base64.
How do I use the Base64 string in HTML? +
Simply copy the generated Data URI (starts with "data:image/...")
and use it in the `src` attribute of an `` tag, or in CSS
as `background-image: url('data:image/...');`.
Is there a file size limit? +
No strict limit, but very large files will result in very long Base64 strings which might be slow to process in the browser. For optimal performance, we recommend images under 5MB.
