base64
An encoding scheme that converts binary data into ASCII text strings. It is commonly used to transmit binary content such as images over HTTP/JSON interfaces, at the cost of roughly 33 percent size inflation.

The fix for D-5 is to base64-encode the ciphertext when writing to Postgres and decode it when reading back, while the model keeps bytes unchanged.
Base64 encoding merely converts binary image data into a character sequence that can be transmitted by text protocols; it does not change the image's own resolution or clarity.
Compared with base64 inlining into JSON or a text prompt, transmitting binary data via multipart avoids the roughly 33% size inflation and extra encoding/decoding overhead caused by base64 encoding.
base64 encoding inflates data size by about 33%, and inlining large images significantly increases request payload; in practice it is often combined with compression or on-demand cropping to balance quality and transmission overhead.
