Optimize images for PNG-24 in Photoshop Elements

The other version is known as WebP Lossless, and it is more like a PNG. You’ll get a higher file size, but you won’t lose detail. PNG-8 / 37kbFor the PNG-8 above, this effect is distorted. PNG-8 images only support one level of transparency, so the transparency only appears in a thin distorted band at the top. JPEGs are a weak choice for images with high contrast. This is why JPEG screenshots with black text on white backgrounds tend to be blurry.

  • PNG-24 is a lossless format and can contain up to 16 million colours.
  • Not only can you create a logo file with a transparent background, but you can also create advanced transparency gradients and more with PNGs.
  • The “8-bit” sample image does not use the full 8 bits of transparency that the PNG format allows.
  • Not only are network speeds relatively slower when compared to dedicated networks, but not everyone has unlimited data.
  • Also, she can provide readers with ways to slove problems on image, video, and auido topics.

Ask Any Difference is made to provide differences and comparisons of terms, products and services. The vision is to cover all differences with great depth. I am Sandeep Bhandari; I have 20 years of experience in the technology field.

Let’s get one thing straight, SVGs are not actually an image file format. SVG is a markup language that allows you to create two dimensional graphics. In addition to supporting background transparency and background matting, the PNG‑24 format supports multilevel transparency. You can have up to 256 degrees of transparency from opaque to completely transparent, so you can blend the edges of an image smoothly with any background color.

The compression rate is different

This difference is not 100% true because Adobe products’ Save for Web command allows PNG-8 with alpha transparency. PNG-24 refers to true color variant, which supports more colors, but might be bigger. PNG-24 can be used instead of JPEG, if lossless image format is needed. In terms of PNG 8 vs. PNG 24 transparency, you can use PNG 8 if your goal is to support a single-bit transparency channel.

In the Save Optimized As dialog box, type a filename, and click Save. This also means that if yo have a graphic like an overlay with a percentage opacity of 50%, it will become fully opaque, since index can only handle a single level of transparency. You will have to use Alpha Transparency to achieve this. I used an annoying red for the background and/or matte color for some of the tests. PNG 8 images can only display 256 colors while PNG 24 images can display up to 16 million colors.

difference between png 8 and png 24

This means that PNG-24 files can contain more than 16 million different colors, making them ideal for storing high-quality images. In addition, PNG-24 files support transparency, meaning that pixels can be set to partially transparent. This can be useful for creating images with smooth edges or for Best Cloud Security Companies  List of Top 10 Cloud Security Providers superimposing images on top of other images. PNG’s strength is its lossless compression algorithm. You don’t lose any data during the compression process so the image can be recreated without a loss of quality. As a result, PNGs preserve the fine detail in images, even when it comes to text.

PNG 8 VS PNG 24: What Is the Distinction and Which Would You Use?

But most other formats, such as index, reverted it to 100% opacity. If you use Photoshop and Illustrator primarily, you’re probably only familiar with PNG-8 an PNG-24. Now that you know the difference between PNG 8 and PNG 24, you can choose which format is best for your needs.

It makes the image look a lot sloppier than it actually is. There are, of course, many other advantages, but those are the ones that matter to web designers. Note that for the sample image below, you would not use PNG-24 because it has simple colors and will also weigh more than GIF. PNG, which stands for Portable Network Graphics, gained popularity and, nowadays, it’s probably the most used image format when it comes to web design, alongside JPEG. In this guide, we will cover everything you, as a web designer, need to know about the PNG image format.

Because more and more visitors are visiting websites on mobile devices. Not only are network speeds relatively slower when compared to dedicated networks, but not everyone has unlimited data. If the image contains transparency, select Transparency to preserve transparent pixels; deselect Transparency to fill fully and partially transparent pixels with the Matte color.

PNG-8 Color Reduction Optimization

So when you’re preparing your images in Adobe Photoshop or Lightroom, don’t be afraid to move that slider over. Lossless image compression, by contrast, preserves data so nothing is lost. Lossless algorithms keep all the necessary data to recreate the image exactly. You can compromise by displaying fewer images or showing them all at a smaller size. Image Optimization begins with choosing the best file format for your needs.

MP4s are another viable option that is compatible with all browsers. You won’t get that pixelation that occurs in other image file types. However, since SVGs were designed to display simple images based on geometric shapes, such as logos, flags, charts and icons. It is imperative that we use the proper file formats when creating professional design work. PNG 24 images allow us to create beautiful, transparent files that blend well with the rest of the site. You can combine these with different CSS, such as multiple backgrounds to create overlapping images that look great.

PNG-8 Vs. PNG-24: There’s a Difference!

When you choose the wrong image format you could be inadvertently serving up a bigger image than is necessary. Additional image file capabilities , unnecessary detail and too many colors all add bloat to your images. Sometimes, these are necessary and other times they’re not. If your image doesn’t have transparency, for example, then you’re really not giving anything up if you choose an image type that doesn’t support transparency. PNG-8 is a PNG format that uses 8 bits per color channel and is thus limited to a palette of 256 colors. PNG-24, on the other hand, uses 24 bits per color channel, allowing for nearly full-color images.

There are two formats available for png images; one is png8 and the another one is png24. Due to its network transmission abilities, designers often use PNG 8 or PNG 24 for web designs. It supports lossless compression, alpha channel translucency and perfectly saves logos, charts, and patterns, among others, in small files and with clear effects. Because the truth is, GIFs were never designed for animations. If you switch over to a WebM file, you’d have a file that is 9 times smaller and a lot higher quality.


It will also support background index & alpha transparency and matte. In general, PNG 24 is a better format to use than PNG 8 for most images. However, there are some cases where PNG 8 can be useful, such as for images that will be used on the web where file size is a concern. If your image does require high quality however – say true color instead of GIFs or JPEGs (they’re not always lossless), then we recommend using PNG-24 images.

Like the GIF and PNG‑8 formats, PNG‑24 preserves sharp details like those in line art, logos, or type. When you unzip your document, it will be the same as the original. On the other hand, JPEG uses a lossy compression algorithm. On the other hand, lossless compression is the opposite of lossy.

Take note, having a higher bit support doesn’t imply that the file format is of higher quality than the lower bit support. Some situations might require you to use lower-bit files. Knowing the different types of file formats is really https://bitcoin-mining.biz/ important when creating professional design work. Choosing the wrong format for your design files can be disastrous. It can mean the difference between a project turning out well, and a project not turning out as expected.

With this, you can have varying percentages of transparency in your graphics and other images. It provides you with 50% opacity on the whole image. The main difference is that a 8-bit PNG comprises a max.

A PNG8 is limited to 256 palette entries, while a PNG24 can have 16 million different colors. PNG-8 is considered the best for small graphics, logos and line art. It is not suitable for complex graphic as it leads to banding on the images. PNG-8 supports transparency of alpha and background index. In case you want to store your image data efficiently, you might consider compressing them.

You can overlay multiple png files, and creating them as like this will allow you to create them without a background. This looks much cleaner than flat jpg files that have backgrounds. They behave similarly to transparent gif files, but contain much more color information and looks much more crisp. You also have smoother transitions from opaque to transparent.
