FAQ
?Why should I convert images to Base64?
Converting small images (like icons or logos) to Base64 and embedding them directly in your HTML or CSS reduces the number of separate HTTP requests the browser must make, which can improve page load speed.
?Is there a file size limit?
Because everything runs in your browser, there is no hard limit imposed by a server. However, very large images will create massive Base64 strings that can freeze your browser or bloat your HTML files, so it is recommended for images under 1MB.
?Is my image uploaded to the internet?
No, the image is converted using the local FileReader API in your web browser. Your file is completely private and never leaves your device.
