Convert JPG to Base64
Encode the original JPEG bytes as a single Base64 string without changing image quality.
Preserve the JPEG file while encoding
The preset disables resizing, metadata removal, and format conversion, so it encodes the selected JPG bytes directly.
Base64 is a text representation rather than image compression and normally increases the payload by about one third.

Frequently asked questions
Does converting JPG to Base64 reduce quality?+
