PNG → JPEG

POST /api/image-png-to-jpeg

Convert a PNG to JPEG. Configurable quality (1–100). Transparency is flattened against a configurable background colour.

Reads a PNG and returns the same picture as a JPEG. Quality is configurable (default 80) — `1` is tiny and ugly, `100` is near-lossless and large. PNG transparency must be flattened because JPEG does not support alpha. The default is to composite over white; pass `background` (a hex colour) to use a different fill.
