About Base64 to JPG Converter

JPEG (Joint Photographic Experts Group) is the most common image format for photographs on the web. It uses lossy compression to reduce file size while maintaining good visual quality.

This tool automatically detects the format and renders it as an image in your browser. Perfect for debugging APIs, testing Data URLs, or inspecting encoded image data during development.

All conversion happens locally in your browser — your data never leaves your device.

Frequently Asked Questions

What is the difference between JPG and JPEG?

There is no difference — they are the same format. JPG is just a shorter extension name used because older operating systems only allowed 3-letter extensions.

Does this support progressive JPEG?

Yes! The tool decodes any valid JPEG Base64 string, including progressive JPEGs that load gradually.

Why is JPEG better for photos?

JPEG compression works well with photographic content where there are smooth gradients and natural variation. It achieves much smaller file sizes than PNG for photos.

Can I convert PNG Base64 to JPG?

No, this tool only decodes Base64 to JPEG. If your Base64 data is PNG format, use the Base64 to PNG page instead.

How do I generate a JPEG Base64 string?

In JavaScript: const canvas = document.createElement("canvas"); const dataUrl = canvas.toDataURL("image/jpeg", 0.8);
