PNG file is one of the most popular image formats. Its most notable advantages are its transparency features and support for over 16 million colors. Because of this, it is often used in web logos, banners, and other image applications.

For this reason, users want to reduce the size of PNG files, so learning how to compress PNG files is a must-go.

How to Compress a PNG on Windows Desktop
In fact, reducing the PNG image storage space is very simple: using the MS Paint application to cut out the image of the unnecessary parts can be done. But this affects the overall quality of the image. This is not the whole picture compression method. Most users need to compress the entire image size, which does not impact the quality of the PNG method. Unfortunately, there are no such built-in tools to help you achieve this. Therefore, using a third-party conversion tool may be your best choice. WorkinTool Image Converter could be a great option.

How to Compress a PNG on Mac
Although the compression features of the WorkinTool image converter are very user-friendly and efficient for most users, unfortunately, it is not yet available for Mac. But the good news is that the Mac system has an optional built-in tool that you can use directly on the MAC to compress standard images. This is the Preview application.
Preview app is a file viewing tool that you don’t need to download. Except for viewing, it is also an image editor that allows users to make some fundamental changes. And today, we will show you how to use it to compress a PDF to a specific size for better storage or sharing.
The specific steps are as follows:
Step 1. Right-click on your PNG pictures, and select Open With > Preview (default).
Step 2. Tap File selection to find Export in the drop-down menu.
Step 3. Move the quality slider to compress the image to the required size. Click Save to save the new compressed file.
Reduce Image size on iPhone
If you’re using an iPhone and want to save space by reducing the size of your images, one of the easiest and most effective ways to do this is to save them in Apple’s proprietary HEIC format. Since the iPhone doesn’t have a direct image compression feature, we don’t recommend cropping out the image itself to reduce the size. So converting to HEIC format is a convenient compromise. HEIC format is smaller and suitable for users to store high-quality photos, but at the same time, the disadvantages are obvious. Its compatibility may be better than PNG.

How to Compress a PNG through Email
Although iOS doesn’t offer image compression, you can still compress images through its email app, and you don’t need to download any other software. The idea is that when you send an e-mail with a picture, the user can compress it to a point where it can be transmitted more easily. Similarly, you can use this feature to send yourself an additional image and download it so that the processed image has been compressed. This method might be more cumbersome than the previous one. But it works.
- Open the Mail app and write a New Message.
- Scroll to the right: Insert Photo or Video, and select the photos you want to compress.
- Click the upper arrow icon to send them.
- Then, you need to select different compress modes to use for photos.
- After it is sent, open the email and download those compressed images.
