  • Files usually get larger, not smaller.
JPG — JPEG image

Lossy raster image — smallest file for photos and renders.

PNG — Portable Network Graphics

Lossless raster image with transparency.

Preguntas de delineantes

Does converting to PNG improve quality?

No. PNG preserves exactly what the JPEG contained; anything the JPEG discarded is gone for good.
