Frequently Asked Questions
Why convert images to Base64?
Converting images to Base64 Data URIs allows you to embed them directly into HTML, CSS, or JSON without requiring the browser to make a separate HTTP request to fetch an image file, which can speed up page rendering for small icons.
Does Base64 encoding increase file size?
Yes. Base64 encoding expands the data size by approximately 33%. For this reason, it is recommended to only encode small images (like icons or logos) rather than large high-resolution photographs.
Is my image uploaded to a server?
No. The conversion happens entirely within your web browser using HTML5 File APIs. Your image never leaves your device, ensuring complete privacy.
