Frequently Asked Questions
What is a Base64 data URL?
A Base64 data URL encodes binary image data as a text string that can be embedded directly in HTML, CSS, or JSON without a separate file.
Does encoding preserve the image quality?
Yes. The image is encoded losslessly as PNG, preserving pixel dimensions and pixel data exactly.
Is the image uploaded anywhere?
No. All encoding happens locally in your browser. The image never leaves your device.
