How Do PNG Files Differ From JPEG Files?

PNG and JPEG (or JPG) are both popular image file formats, but they differ in various aspects:

Compression Algorithm: 

PNG (Portable Network Graphics) files use lossless compression to preserve all image data and maintain high quality. On the other hand, JPEG (Joint Photographic Experts Group) files use lossy compression, which sacrifices some image details to achieve smaller file sizes.

Color Support: 

PNG files support a wide range of colors and can handle transparency, making them ideal for graphics and images with sharp edges or text. JPEG files, however, support millions of colors but do not support transparency.

File Size: 

JPEG files have smaller file sizes than PNG files due to their lossy compression. It makes JPEGs suitable for web usage and large collections of photos, where smaller file sizes are beneficial for faster loading times and efficient storage.

Image Quality: 

PNG files maintain high image quality without compression artifacts, making them perfect for images that require crisp details. While providing good quality, JPEG files may exhibit compression artifacts and a slight loss of quality due to their compression method.


PNG files are commonly used for graphics, logos, icons, and images that require transparency. JPEG files are widely used for photographs and images where color variation is more important than preserving fine details.

Method 1: Using Preview

Open the PNG file: 

Locate the PNG file you wish to convert and double-click on it. By default, it should open in the Preview application on your Mac.

Access the Export function: 

Once the PNG file is open in Preview, click on the "File" menu at the top-left corner of the screen. From the dropdown menu, select the "Export" option.

Choose the JPG format: 

In the export window, you'll see various options to customize your export settings. Select "JPEG" from the "Format" dropdown menu. If desired, you can also adjust other locations, such as quality, resolution, and color profile.

Specify the save location:

Choose the destination folder where you want to save the converted JPG file. You can select an existing folder or create a new one by clicking the "New Folder" button.

Export the file: 

Once you've chosen the save location, click the "Save" button to initiate the conversion process. Preview will convert the PNG file to JPG format using the specified settings.

Method 2: Utilizing GraphicConverter

GraphicConverter is a powerful third-party application that provides extensive image conversion capabilities. Here's how you can use it to convert PNG to JPG on your Mac:
