Frequently Asked Questions
Got questions about Base64? We've got answers.
What is a Base64 data URI?
A Base64 data URI embeds image data directly into a string that can be used in HTML, CSS, or JavaScript without requiring a separate file request.
When should I use Base64 images?
Base64 is useful for small images like icons or sprites where you want to reduce HTTP requests. For larger images, file URLs are more efficient.
Is Image to Base64 safe?
Yes, absolutely. All processing happens entirely in your browser — nothing is uploaded to any server.
