How to convert PNG to JPG on MAC - Offline and online
How to convert PNG to JPG on MAC - Offline and online? Here we have a simple guide that will easily help you convert your PNG image to JPEG format on your MAac computer.
There are undoubtedly many web tools online there that will allow you to do this. But some are paid, whereas others will affect the quality of the image after converting to PNG.
JPG is a digital image format that contains compressed image data. With a 10:1 compression ratio, JPG images are very compact. JPG format contains important image details. This format is the most popular image format for sharing photos and other images on the internet and between Mobile and PC users.
On the other hand, Portable Network Graphics is a raster graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format — unofficially, the initials PNG stood for the recursive acronym "PNG's Not GIF".

PNGs usually contain more data than JPEGs as both use different compression methods. As PNGs contain more data than JPEGs, they are, therefore, generally usually larger in size. This will therefore indicate that JPEG images are smaller in size.
Lossless vs. lossy compression.
It’s important to understand the different compression processes each file type uses when considering whether to use JPEG or PNG as your file type.
JPEGs are designed to efficiently store high-quality digital photos packed with detail and color. They compress large images into much smaller file sizes, making them easier to share and upload online. But this comes at a price.
JPEGs use a lossy compression process — meaning some data from the image is permanently deleted when it’s made smaller. This could compromise the quality of your file in the long term because each time you edit and save it, you lose more data. Because of this, some professional photographers prefer using uncompressed raw files.
In contrast, PNG files benefit from lossless compression. This means no data is lost when the image is compressed — the quality stays the same no matter how many times you edit and save the file. The image won’t become blurry or distorted, making PNGs ideal for sharp logos and graphs containing lots of figures.
Disadvantages of DWG files.
They may compromise on quality with their lossy compression, but JPEGs can crunch large images down into more manageable file sizes. This is helpful if you don’t have a huge amount of disk space to play with — and can speed up page loading times, too.
The trade-off with PNGs is that their lossless compression creates bigger files since they retain much more information. They’re generally larger than JPEGs and GIFs, use up additional storage space, and potentially slow down the responsiveness of web pages.
One of the major differences between JPEG and PNG files is their ability to handle transparency in images.
JPEGs don’t support transparent backgrounds. Non-rectangular logos and graphics featuring lots of text are unlikely to work well in this format as a result. JPEG images will also struggle to blend seamlessly with web pages that feature different background colours.
PNG files, on the other hand, do support transparency. Web designers can apply transparent backgrounds to their images – and even different degrees of transparency. It means PNG images integrate better with different background colours on a page and text is easier to read.
Digital photos vs. web graphics.
JPEGs are hugely popular with photographers and businesses that manage large image libraries. Their smaller file size allows multiple digital photos to be shared and downloaded simultaneously. By making efficient use of storage space, JPEGs can keep an image library relatively streamlined, with no long wait times for files to open.
Given their widespread usage, JPEG files are viewable and editable across a vast array of operating systems and programs — so you’re unlikely to need specialized software to work on them.
In comparison, PNGs aren’t really built to store high-quality photos. They specialize in handling detailed, high-contrast web graphics. They’re often the default format for screenshot images since they can provide a highly accurate representation of your desktop and don’t compress pixels together. A huge colour palette and lossless compression ensure they retain plenty of detail — making them a popular choice for illustrations and charts.
The ability of PNGs to handle transparent images also gives them an edge over JPEGs when designing logos. For example, you can create a company logo with a transparent background, and then seamlessly layer it on top of other images or web pages.
As with JPEGs, you can open PNGs in many programs and web browsers. PNGs were specifically designed to be an upgrade on the older GIF format — meaning they’re patent-free and offer a much broader choice of colours.
How to convert PNG to JPG on MAC - Offline
Preview can convert image files to many file types including JPEG, JPEG 2000, PDF, PNG, PSD, TIFF, and others. This can be useful if you share files with people who use other kinds of computers or if you want to open files in apps that don’t read all file types.
In the Preview app on your Mac, open the file, then choose File > Export.
Click the Format pop-up menu, then choose a file type.
If you don’t see the file type you want, press and hold the Option key and click the Format pop-up menu to see specialized or older formats.
Depending on the file format you choose, additional options may appear. If you choose JPEG or JPEG 2000, you can adjust the image’s quality. If you choose PDF, you can choose a Quartz filter to apply to the image, and you can encrypt the image so that only those with the password can view it.
Type a new name, or choose a new location for saving the converted file, then click Save.
