JPG vs PNG — Which should you use?
Use JPG for photographs. Use PNG for logos, screenshots, icons, and any image requiring transparency or repeated editing.
No — the original JPEG compression is already baked in. Converting to PNG prevents further quality loss on future saves.
PNG is lossless — it stores more data. That is normal and expected.
