Will transparency be preserved?

No. JPEG does not support transparency. Any transparent areas in the PNG will be composited against a white background in the output.

What quality value should I use?

A quality of 85–90 typically produces a visually near-identical image at a significantly smaller file size than the original PNG. Lower values save more space but introduce visible compression artefacts.

Is there a file size limit?

There is no hard limit enforced by the tool, but very large images may be slow to process depending on your device's memory and CPU.

The PNG to JPEG converter uploads a PNG file, renders it on a canvas, and exports it as a JPEG using canvas.toBlob with a configurable quality level. The tool displays the original PNG size alongside the resulting JPEG size so you can find the right quality/size trade-off. Transparency is composited against a white background.
