Frequently Asked Questions
What is Base64 encoding for images?
Base64 encoding converts binary image data into a text string using 64 ASCII characters. This allows images to be embedded directly in HTML, CSS, or transmitted as text in APIs and databases.
Which image formats are supported?
Our converter supports all common image formats including JPG/JPEG, PNG, GIF, WebP, BMP, and SVG. The maximum file size limit is 10MB for optimal performance.
Is my image data secure?
Yes, absolutely! All conversion happens locally in your browser using JavaScript. Your images are never uploaded to our servers or transmitted anywhere. Your data remains completely private.
How do I use Base64 images in HTML?
Use the format: <img src="data:image/png;base64,YOUR_BASE64_STRING">. Replace "png" with your image format and "YOUR_BASE64_STRING" with the generated code.
Are there any disadvantages to Base64 images?
Base64 encoded images are about 33% larger than the original file size and cannot be cached separately by browsers. They're best for small images, icons, or when you need self-contained files.
