Frequently Asked Questions
Why would I use Base64 images?
Base64 images are embedded directly in your code, eliminating extra HTTP requests. This is useful for small images (icons, logos), email templates, and single-file applications. However, Base64 increases file size by ~33%, so it's best for images under 10KB.
What image formats are supported?
We support PNG, JPEG, GIF, WEBP, SVG, ICO, and BMP. The converter automatically detects the image type and generates the correct MIME type in the Data URI.
Is my image uploaded to a server?
No. All processing happens directly in your browser using the FileReader API. Your images never leave your device, ensuring complete privacy.
Why is the encoded string larger than my original file?
Base64 encoding converts binary data to ASCII text, which increases size by approximately 33%. This is normal and expected. For larger images, it's usually better to use regular image files.
