Frequently Asked Questions
What is the difference between Data URI and Plain Base64?
Data URI includes the MIME type prefix (e.g., data:image/png;base64,...) and can be used directly in HTML img src or CSS background-image. Plain Base64 is just the encoded string without metadata, useful for APIs or databases.
Is there a file size limit?
There is no hard limit, but very large images (above 10MB) may be slow to process. Base64 encoding increases file size by roughly 33%, so keep that in mind for performance.
Are my images uploaded to a server?
No. All encoding happens in your browser using the FileReader API. Your images never leave your device.
