Which formats are supported?

This tool only supports JPG/JPEG files (image/jpeg). Only JPG/JPEG files can be uploaded and processed. Other file types will be rejected to ensure data integrity and proper encoding/decoding.

How do I use Base64 JPG/JPEG in HTML?

Use the Base64 string in an img tag or download link with the data URI format: Download JPG/JPEG

Can I use Base64 JPG/JPEG in JSON?

Yes! Base64 JPG/JPEG images are commonly used in JSON APIs to send images as text strings: { "image": "data:image/jpeg;base64,YOUR_BASE64_STRING", "filename": "image.jpg", "type": "image/jpeg" }

Why is the Base64 string longer than the original file?

Base64 encoding increases the size of binary data by approximately 33%. This is because Base64 uses 4 characters to represent every 3 bytes of binary data. A 1MB JPG/JPEG image will result in approximately 1.33MB of Base64 text.

Is my file uploaded to a server?

Yes! All JPG/JPEG processing happens entirely in your browser using JavaScript. Your images are never sent to any server, stored, or shared. Everything is processed locally on your device, ensuring complete privacy and security.
