Will I lose image quality when editing and re-saving an existing png file?

Question

I know that each time a .jpg file is saved, it is compressed and loses quality.

Is the same true for .png files?

While being compressed a png image still is lossless. If you change parts of your image and re-save the quality of the image is still the same!

though it depends on how you've saved it. If it was an 8-bit png, and you edit it adding color outside the compressed pallet, colors may shift as it gets resaved.

You could. Depends on how you re-save it. I would select png24 8bit. That will keep the quality high.
