Difference Between JPEG and PNG Files – Which One To Choose

If you are in the creative field and work with digital images, you always have to choose between various formats like PNG, JPEG, and so on. But do you know which one is right for you?

Today, in this article, we will cover the difference between JPEG and PNG image formats, what each of them offers, and when it’s best to use them. So, let’s get right to it!

What is a JPEG file?

A JPEG file is a type of image file that most people use for photos. It means Joint Photographic Experts Group, which created this format. 

JPEGs are super popular because they compress images, making the files smaller without losing too much quality. This makes them perfect for sharing pictures online or storing lots of them on your devices. 

However, because of this compression, some details might be lost, so it’s not the best for super high-quality prints. But for everyday use, like posting on social media or saving family photos, JPEGs are just suitable.

What is a PNG file?

A PNG file is a kind of image file that’s great for graphics. PNG stands for Portable Network Graphics. 

Unlike JPEGs, PNGs don’t lose quality when you save them, so they keep all the details sharp and clear. This is handy for images with text, logos, or transparent backgrounds because the quality stays high. 

They can be a bit larger than JPEGs, but they’re perfect for a crisp, clear image. So, if you’re working on web design or need a high-quality image that has a transparent background, PNGs are the way to go.

Difference Between JPEG and PNG Files

Now that we know a little about these two file types, let’s examine the difference between a PNG and JPEG file in more detail.

Image Compression in JPEG and PNG Files

Compression is a method of altering an image to take up less memory space. As a designer, you must use the appropriate compression methods and a robust image compressor, as it greatly impacts the final product. 

But what difference does it make? 

Lossy Compression with JPEG

JPEG uses something called lossy compression. The best way to explain what that means is to see how it changes the image.

• Reduces file size by discarding some image data.
• There is a slight loss of quality each time you save.
• It is ideal for photographs and images that have many colors.
• Smaller file sizes make it great for web use and storage.

Generally, JPEGs are the standard for web images. Because they take up less memory, they don’t hinder page load times, which makes them perfect for blogs and articles.

Lossless Compression with PNG

On the other hand, PNGs use something called lossless compression. Let’s see how it works:

• Maintains all image data without loss of quality.
• Larger file sizes compared to JPEG.
• Perfect for images with text, graphics, and transparent backgrounds.
• Ensures high-quality visuals, even after multiple saves.

Generally, PNG is the way to go when you know the image will be displayed on a large scale (e.g., backgrounds or big header images).

JPEG vs PNG File Size Comparison 

When it comes to file size, JPEGs and PNGs have notable differences. 

JPEG files are generally much smaller because they use lossy compression that reduces the file size by sacrificing some image quality. This makes JPEGs perfect for storing lots of photos or sharing images online, where quick loading times are important.

On the other hand, PNG files are typically larger because they use lossless compression. This method preserves all the image data, resulting in higher quality and bigger file sizes. 

PNGs are ideal for images that need to maintain sharp details, like logos or graphics with transparent backgrounds, but they take up more storage space.

PNG’s Support for Transparent Backgrounds

The most critical difference Between PNG and JPEG images is that if you need to remove the background in your image, PNG is the way to go. 

PNG allows parts of the image to be fully or partially transparent. This means this format is perfect for logos, icons, and graphics, as you should be able to place them anywhere, no matter the background. 

Additionally, PNG supports various levels of transparency, making it versatile for web design and digital art. JPEG doesn’t support transparency and always has a solid background, which can be limiting for design flexibility.

JPEG vs PNG: Which Should You Choose? 

Now that we know the key differences between these two very popular formats, it’s time to decide. But all we’ve listed so far are just facts. What about real-world examples? 

When To Choose JPEG?

The JPEG format is the way to go for: 

• Photographs
• Web Use
• Storage Efficiency

Family vacation photos benefit from being in JPEG format, as you can store hundreds or even thousands of pictures without using excessive storage space on your device or cloud service. Additionally, for blog posts and social media images, JPEGs ensure that your content loads quickly, keeping visitors engaged and reducing bounce rates.

When To Choose PNG?

The PNG format should be chosen for: 

• Graphics and Logos
• Transparency Needs
• High-Quality Visuals

Company logos and infographics benefit from being in PNG format. This format ensures they look professional and transparent, which is even more valid for website icons.

Whenever you need something to be transparent, you should use PNG. Moreover, they preserve their original quality no matter how often they are edited or saved.

JPEG vs. PNG: Summarized Comparison

Feature	JPEG	PNG
Compression	Lossy	Lossless
File Size	Smaller	Larger
Best For	Photographs	Graphics and logos
Transparency	Not supported	Supported
Image Quality	Good, slight loss with compression	Excellent, no quality loss
Use Cases	Web images, social media, photo albums	Digital art, web design, detailed images
Storage Efficiency	High	Lower

Conclusion – JPEG or PNG

Choosing between JPEG and PNG formats depends on your needs and the nature of your project. JPEGs are ideal for everyday photos, web use, and situations where storage space is a priority. Their smaller file size and good quality make them perfect for sharing images online quickly and efficiently.

On the other hand, PNGs are the go-to for graphics, logos, and any images requiring transparency or high detail. PNGs maintain image quality with lossless compression, making them ideal for professional designs and digital art.

Understanding the strengths and weaknesses of each format helps you select the right one for your needs, ensuring your images always look their best.
