Frequently Asked Questions
What is Base64 encoding for images? +
Base64 encoding converts binary image data into a text string using only ASCII characters. This allows you to embed images directly in HTML, CSS, or JSON without needing a separate image file.
Why would I convert an image to Base64? +
Base64 images can be embedded directly in HTML or CSS, reducing HTTP requests and simplifying deployment. They're useful for small icons, email templates, and single-file applications where you want everything self-contained.
Does Base64 increase file size? +
Yes. Base64 encoding increases the data size by approximately 33%. This is why it's best suited for small images like icons and logos. For large images, linking to a separate file is usually more efficient.
What image formats are supported? +
This tool supports all common image formats including PNG, JPG/JPEG, GIF, WebP, SVG, BMP, ICO, and TIFF. Any image your browser can display can be converted to Base64.
Is my image data sent to a server? +
No. The entire conversion happens in your browser using the FileReader API. Your image data never leaves your device, ensuring complete privacy and security.
