What is Base64 encoding for images?

Base64 encoding converts binary image data into ASCII text characters. This allows images to be embedded directly in HTML, CSS, or JavaScript code as data URIs, eliminating the need for separate image file requests.

What's the difference between including and excluding the data URI prefix?

The data URI prefix (data:image/jpeg;base64,) tells browsers how to interpret the Base64 string. Include it for direct use in HTML/CSS. Exclude it when you need just the raw Base64 data for APIs, databases, or custom processing.

Will the Base64 output work in all browsers?

Yes, Base64 data URIs are universally supported by all modern browsers including Chrome, Firefox, Safari, Edge, and even older versions of Internet Explorer. JPG is the most compatible image format.

Why is the Base64 string larger than the original file?

Base64 encoding increases file size by approximately 33% because it converts binary data to ASCII text. This trade-off is acceptable for small images where reducing HTTP requests is more valuable than the size increase.

Can I use the Base64 output directly in my code?

Yes, with the prefix included, the output is ready to paste directly into HTML img src attributes, CSS background-image properties, or JavaScript code. Without the prefix, you can use it in API payloads or custom implementations.

Is there a file size limit for conversion?

Our tool supports JPG files up to 50MB. However, for practical use, Base64 encoding is most beneficial for smaller images under 100KB to avoid bloating your HTML or CSS files.

Are my images secure when using this converter?

Absolutely. All image processing happens locally in your browser. Your JPG files never leave your device or get uploaded to any server, ensuring complete privacy and security.

What's the difference between JPG and JPEG?

JPG and JPEG are the same format - JPEG stands for Joint Photographic Experts Group. The .jpg extension was used in early Windows systems that required 3-character extensions. Both extensions are fully supported by this tool.
