FAQ
What image formats are supported?
JPG, JPEG, PNG, WebP, SVG, and GIF images are supported. The data URI uses the original MIME type of your file.
Is there a size limit?
You can upload images up to 25 MB. Keep in mind that Base64 encoding increases the data size by about 33%, so very large images will produce very long strings.
Are my images uploaded to a server?
No. The conversion happens entirely in your browser using the FileReader API. Your images never leave your device.
When would I use an image as Base64?
Base64-encoded images are useful for embedding small icons or assets directly in HTML, CSS, or JSON — eliminating an extra network request. They're common in emails, data URIs, and single-file applications.
