Convert to PNG when you need transparency support, lossless quality, or are working with graphics, logos, or images with text. PNG is also better if you need to repeatedly edit and save the image without quality degradation.
No, converting JPG to PNG won't recover lost quality from JPG compression. However, it prevents further quality loss if you edit the image multiple times. Once saved as PNG, future edits won't degrade quality like they would with JPG.
Yes, PNG files are typically 2-3 times larger than JPG because PNG uses lossless compression. The trade-off is perfect quality preservation and transparency support, which JPG cannot provide.
Use PNG for logos, graphics with text, images requiring transparency, screenshots, or any image you'll edit multiple times. Use JPG for photographs and when file size is more important than perfect quality.
Yes! Unlike JPG, PNG supports transparency. However, converting an existing JPG to PNG won't make the background transparent - you'd need to edit the image to remove the background separately.
