Step 1.1: Using Spotlight

If you’re not sure where the Preview app is located on your Mac, you can use Spotlight to search for it. Simply press the Command + Spacebar keys on your keyboard to open Spotlight, then type in “Preview”.

Step 2: Open the PNG file

The next step is to open the PNG file you wish to convert to JPG in Preview. To do this, simply drag the PNG file into the Preview window or click on File > Open and select the PNG file you want to convert.

Step 3: Click on File > Export

After opening the PNG file in Preview, click on File > Export. This will open the Export dialog box, which will allow you to select the format and options for the exported file.

Step 4: Select JPEG as the Format

In the Export dialog box, select JPEG as the format for the exported file. You can do this by clicking on the Format drop-down menu and selecting “JPEG”.

Step 5: Adjust the Quality

You can adjust the quality of the exported file by moving the Quality slider to the left or right. A higher quality file will result in a larger file size, while a lower quality file will result in a smaller file size.

Step 6: Choose the Destination Folder

Choose the location where you want to save the exported file by clicking on the “Where” drop-down menu and selecting a folder on your Mac. You can also create a new folder by clicking on the “New Folder” button.

Step 7: Name the File

Type in a name for the exported file in the “Name” field. You can also choose whether or not to append the file format to the name by selecting the appropriate option.

Step 8: Click on “Save”

After setting the options for the exported file, click on the “Save” button to save the file to the location you selected.

Step 9: Drag and Drop

Alternatively, you can simply drag and drop the PNG file into the desired location and drop it. This will automatically convert the PNG file to a JPG.

Step 10: Use Automator

If you need to convert a large number of PNG files to JPG, you can use Automator to create a workflow that will automate the entire process. To do this, open Automator, select “Workflow” as the type of document, and drag the “Change Type of Images” action to the workflow window.

Step 11: Customize

Customize the options for the “Change Type of Images” action to ensure that the input and output files are set to PNG and JPEG, respectively. You can also specify any other options you want for the conversion process.

Once you have customized the workflow, save it, and run it by clicking on the “Run” button. This will convert all the PNG files in the specified folder to JPEG.


Now that we’ve gone through the 12 simple steps on how to convert PNG to JPG on Mac, let’s take a closer look at some of the key concepts involved in the conversion process.

Firstly, it’s important to remember that PNG and JPG are two different file formats that serve different purposes. While PNG files are typically used when you need to preserve transparency or for high-quality graphics, JPG files are best suited for photographs and other images where color accuracy is less important.

The Preview app on Mac is the most popular tool used to convert PNG to JPG, thanks to its user-friendly interface and powerful features. It allows you to adjust the quality of the output file, select the destination folder, and name the converted file in just a few clicks.

Another important tool that can save you time and effort when converting PNG files to JPG is Automator. This powerful app allows you to automate repetitive tasks by creating workflows that can be executed with a single click. By using Automator, you can convert hundreds of PNG files to JPG in just a few minutes, without having to spend hours manually converting each file.

Tips and Tricks:

Tip 1: Use the “Export As” Option

If you’re using an older version of Preview that doesn’t have the “Export” option, you can use the “Export As” option instead. This can be accessed by clicking on File > Export As, and will allow you to export the PNG file as a JPG with just a few clicks.

Tip 2: Use Batch Processing

If you have a large number of PNG files to convert to JPG, you can use batch processing to speed up the process. Simply select all the PNG files in Finder, right-click on them, and choose “Open With” > “Preview”. This will open all the selected files in Preview, and you can then use the Export or Export As options to convert them to JPGs.

Tip 3: Use an Online Converter

If you don’t have access to a Mac or prefer not to use the Preview app, you can also use an online converter to convert PNG to JPG. There are many free online converters available that allow you to upload your PNG file, select JPEG as the output format, and convert the file in just a few clicks.

Tip 4: Save Disk Space

To save disk space and minimize the size of your JPG files, you can adjust the compression level during the conversion process. Simply slide the Quality slider to the left to reduce the file size, without sacrificing too much quality.

Tip 5: Experiment with Color Profile

By experimenting with the color profile settings, you can achieve better color accuracy and improve the overall quality of the converted image. You can do this by selecting the “ICC Profile” option under the “Color Profile” heading in the Export dialog box.

Tip 6: Use a Third-Party Tool

There are many third-party tools available that can help you convert PNG files to JPG on Mac, such as GraphicConverter and Adobe Photoshop. While these tools may be more complicated to use, they offer more advanced features and customization options.

Tip 7: Check the Resolution

When converting PNG files to JPG, it’s important to check the resolution of the output file, especially if you’re planning to use it for printing or other high-resolution applications. Make sure that the resolution is set to at least 300 dpi for best results.

Tip 8: Stick to the Same Naming Convention

To avoid confusion and ensure that your files are organized, it’s important to stick to the same naming convention when converting PNG files to JPG. Use a consistent format for the file names, such as “filename.png” and “filename.jpg”, to make it easier to find and organize your files.

Tip 9: Keep a Backup of the Original File

Before converting the PNG file to JPG, make sure to keep a backup of the original file in case you need to revert back to it later. This will help you avoid losing important data and ensure that you have a copy of the original file for future reference.

Tip 10: Stay Organized

To stay organized and avoid clutter, make sure to keep your converted files in separate folders based on their type or purpose. This will help you keep track of your files and avoid confusion, especially if you’re working with large numbers of files or collaborating with others.

In conclusion, converting PNG files to JPG on Mac is a simple process that can be done using the Preview app or other third-party tools. By following the easy steps outlined in this article and using the tips and tricks provided, you can convert your PNG files to JPG quickly and easily, saving time and effort in the process.
