About the JPG format
JPG (or JPEG) is the most widely used image format on the web. It uses lossy compression that keeps photos small in file size, and it is supported by virtually every device, browser, app and online form ever made.
Why convert to PNG?
PNG is a lossless image format that preserves every pixel exactly and supports transparency. It is the standard choice for logos, screenshots, graphics with text and anything that needs a transparent background. Choose PNG when quality matters more than file size, or when you need transparency — for logos, screenshots and graphics.
