Convert a JPEG before adding annotations
PNG keeps the pixels decoded from the source JPEG and avoids another lossy JPEG export during this conversion. It cannot restore missing detail or create transparency from a white background. Compare file sizes if the output is for an upload.

JPG to PNG questions
Short answers, then the practical details.
Does JPG to PNG improve image quality?
No. Converting to PNG preserves the pixels decoded from the JPG but cannot restore detail removed by earlier JPEG compression. The result avoids a further JPEG encoding step, which can be useful for editing workflows, but simply changing the format does not make the source image sharper.
Can JPG to PNG restore a transparent background?
No. A JPG contains no alpha transparency channel, so converting it to PNG does not automatically remove its background or recover earlier transparency. The visible background remains part of the image. Use Remove Background if you need a transparent cutout.
Why is the converted PNG larger than the JPG?
PNG uses lossless pixel encoding, while JPEG usually stores photographs more compactly through lossy compression. A larger PNG is therefore a normal conversion outcome, not evidence of extra detail. If you need a smaller attachment, keep the JPG or use the image compressor and compare actual output sizes.
