About Image to Base64 Converter
Encode an image as text for a development workflow that accepts embedded data. Keep the data URL prefix when the receiving field expects a MIME type, or omit it when only the Base64 payload is needed. Encoding usually increases the data size.

What to know about Image to Base64 Converter.
Does Base64 make an image smaller?
No. Base64 usually adds about one-third to the encoded data size. Use it when an integration requires text data, rather than as image compression.
Are my files uploaded for processing?
No. File contents are processed in your browser. The site, codecs and any required models still need to load over the network; local results depend on your device and browser.
