- 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.
よくある質問
Does converting to PNG improve quality?
No. PNG preserves exactly what the JPEG contained; anything the JPEG discarded is gone for good.
