Frequently Asked Questions

What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to embed images in HTML, CSS, and JSON files without needing separate image files. Base64 encoding increases file size by about 33%, but eliminates additional HTTP requests.
Why convert images to Base64?
Converting images to Base64 allows you to embed them directly in your code, reducing HTTP requests and simplifying deployment. This is especially useful for small images like icons, logos, and backgrounds. However, for large images, it's often better to keep them as separate files for caching purposes.
Are my images uploaded to a server?
No. All image processing happens locally in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security. No data is transmitted to any server.
What image formats are supported?
We support all common image formats including JPG, JPEG, PNG, GIF, WebP, SVG, BMP, and ICO. The converter automatically detects the file type and generates the appropriate Base64 encoding with the correct MIME type.
Is there a file size limit?
Yes, individual files are limited to 10MB, and you can convert up to 20 files at once. For most use cases like icons, logos, and small images, this is more than sufficient. Large images should be optimised before converting to Base64.
Can I use the converted Base64 in production?
Absolutely! The Base64 output is standards-compliant and works in all modern browsers. Choose the appropriate output format for your use case: Data URI for direct embedding, CSS for stylesheets, or HTML for img tags.
