Learn More About the Settings

Our PNG to JPG converter has an uncluttered and pretty straightforward interface. Nevertheless, you’ll have a decent amount of control over the final result. Let’s take a look at what settings you can find in Watermarkly:

Pick the Quality of your JPGs

Before we begin, there’s something you need to be aware of. Generally speaking, JPG images tend to have a smaller file size than PNG images. In addition to this, PNGs usually have a better quality than JPGs – this is mostly due to the fact that PNG is a lossless format whereas JPG is a lossy format. In other words, when you process PNG files, no information is lost. But if you process a JPG file, some loss of information occurs. You need to be aware of both of these things because your JPG image won’t be exactly the same as its PNG original. After the conversion, you’ll get an image that has a different file size and image quality no matter what. But how drastic these changes will be depends on which option in the settings you choose.

Here are the options that Watermarkly offers:

  • Standard quality. This option produces images of a regular file size. There will be some loss of image quality, but it won’t be too drastic. You will mostly see it if you zoom in on your converted files. This is a great option if you need to convert PNG to JPG to post your images on social media, for instance.
  • Maximum quality. If you go for this option, you’ll get JPG images of the highest quality possible. What you need to know about this option is that the file size of your JPGs will be almost the same or maybe even bigger than of the original PNGs. This is a perfect option for you if you prioritize the image quality over the file size.
  • Standard quality with compression. The difference between this option and the first one is that here the app will compress the PNG images as well as convert them. Compressing an image means removing redundant pixels and other unnecessary information from it. This option will produce JPGs of a smaller file size than the first one. The quality will be slightly lower, too, but it will still be good enough. You might need to go for this option if you want to publish images on your website. This way, your JPGs will look good, yet they won’t occupy too much space on your server.

Pick the Size of Your JPGs

Our PNG to JPG converter allows you to resize your processed images. Please note that here you can enter new values for the pixel dimensions of your image, not its file size.

Here are the most popular options that might be useful for you:

  • Do not resize. The pixel dimensions of your JPG images will be the same as the pixel dimensions of your PNG originals.
  • Exact height. This option allows you to change the height of your JPGs by entering a new number of pixels.
  • Exact width. This is similar to the previous option, but here, you’ll be able to change only the width of your JPGs.
  • Exact height and width. This is a combination of the first and the second options. You’ll be able to change both the height and the width of your JPGs by entering new values for pixel dimensions. This is a perfect option if you want to meet certain size requirements; for instance, if you want to publish your images on a social media platform. Please note that you might need to change the aspect ratio of your image by cropping it; this option can be chosen in the app.

Aside from these three popular options, you will find two more. You can type in values for maximum pixel dimensions. In other words, you won’t get these exact pixel dimensions, but the height and the width of your converted image won’t be bigger than the values that you entered. If your image needs to be smaller, but you don’t care about specific pixel dimensions, you can resize your image by a certain number of percent. For instance, if you enter 60 percent, your image will be smaller by 40% once the app converts it from PNG to JPG.

More About the PNG Format

The PNG (Portable Network Graphics) format was developed to replace the outdated GIF format in the late 1990s. The main goal of its developers was to create a format that provides lossless compression, supports transparency and produces images with a wider range of colors than GIF.

One of the key advantages of PNG is that it has alpha channel support, which allows for creating images with transparency. Naturally, it’s extremely useful if you want to design a logo, an icon or an image with transparent areas. For instance, if your logo needs to have a transparent background so you could easily add logo to your images as a watermark.

Another benefit of PNG is that it supports lossless compression. It means that an image can be compressed without removing any information from it, thus there will be no loss of quality. If necessary, you’ll be able to restore a compressed file to its original state without any issues. However, this comes with a bit of a cost – PNG images tend to have a slightly bigger file size than, say, JPGs. They won’t be drastically big, yet this is something you need to be aware of.

Another drawback of this format is that it’s not suitable for images with lots of details. In other words, it doesn’t handle photos all that well. So, if you are a photographer, you’ll have to save your images in JPGs; even though it’s a lossy format. PNG is often used for images with flat colors, text, line art, or images that need to have transparent areas.

PNG also supports various color spaces, including grayscale, indexed colors, and full-color images. This makes it a versatile format that’s suitable for various types of images. The PNG format is a perfect choice if transparency and no quality loss are crucial for you.

Several Reasons Why It's Worth Converting PNG to JPG

If you are not sure why you might need to change PNG to JPG, here are several reasons:

  • Smaller file size. The file size of JPG images tends to be smaller than of PNG images. You can see that if you compare one and the same image with the exact same pixel dimensions, but one file is in JPG and the other is in PNG. You will see that the PNG is bigger. You might need an image to have a smaller file size to meet the size limitations of a mail service or a messenger. Another example is if you need to post an image on a website. Your image will load faster on a webpage if it has a small file size. It will save bandwidth and improve your website’s performance.
  • Disk space. Since PNGs have a bigger file size, they will take up more memory of your device. If you constantly face the problem of running out of memory space, it might be a good idea to convert PNG to JPG. This will help empty some disk space.
  • Quality preservation. Even though JPG is a lossy format, if you use the right settings, the loss of information during compression will be minimal and you’ll be able to retain high image quality. This might be especially useful for converting photos and other types of images that have a lot of fine details and complex textures; you might’ve noticed that in most cases, they become less sharp and clear after compression.
  • Compatibility. This is probably one of the most common reasons to convert PNG to JPG. Naturally, a lot of modern browsers, software and apps tend to support PNG. However, this format is nowhere nearly as popular as JPG, which is supported by practically all devices, operating systems, social media platforms, etc. For instance, Instagram advises its users to post images only in JPG.
  • Ease of use. Since JPG is widely used and tends to produce images of a smaller file size, this format is more convenient for data exchange, editing photos and sharing them online.

Surely, PNG has its own advantages. This format is great if transparency support is required. It can be a perfect choice if an image contains some text and a lot of sharp lines – you will get much better results with PNG than with JPG. However, there are quite a lot of cases where converting PNG to JPG might be not only preferable, but highly crucial.
