The Difference Between PNG8, PNG24, and PNG32
Contents
These advanced capabilities means that PNG-32 produce much larger file sizes. If you’re not creating an image that needs complex transparency, stick with the PNG-24. If you’re creating an image overlay that fades to nothing, then that’s a job for PNG-32. https://topbitcoinnews.org/ Aside from using lossless compression, PNG is a bitmapped image format, which just means it’s a raster image format. If you skipped Design 101, raster images, unlike vector image formats such as SVG, cannot be rescaled without losing quality.
A picture with a single color is suitable for storage in the PNG-8 format. Under the premise of lossless compression, the file can be losslessly compressed to the minimum without any impact on the definition. PNG-8, like the GIF format, only supports a 1-bit Boolean transparency channel. The edges of the transparent and opaque areas of the picture are relatively rigid and do not support translucent effects. According to the PNG 8 format, which is made for showing images on the Internet, it normally does not lose too much data and can produce smaller sizes.
The PNG specification only defines “png”, which can come in a variety of different bit depths and color types (RGB, RBGA, Gray, Gray-alpha, indexed). The “PNG8” nomenclature is simply a convenient way of referring to an indexed (8-bit pixels) image. ImageMagick, for example, uses PNG8, PNG24, PNG32, PNG48, and PNG64, to identify 8-bit indexed with binary transparency, 24-bit RGB, 32-bit RGBA, etc. I’m not sure whether PhotoShop’s definition limits PNG-8 to binary transparency or not.
PNG‑24 format is suitable for compressing photographs. However, PNG‑24 files are often much larger than JPEG files of the same image. PNG‑24 format is recommended only when you work with an image that includes multiple levels of partial transparency. Let’s compare the advantages and disadvantages of using PNG versus the two other popular web image formats. However, raster images are better than vector images for complex images such as photographs.
Unlike GIFs though, PNG-8 has poor animation support. PNG-8 is ideal for simple web graphics with transparent backgrounds, such as logos and site icons. The answer lies in how many colors are used to create an image. PNG-8 uses 8 bits per pixel while PNG-24 uses 24 bits per pixel. This means that PNG-8 can only produce 256 colors while PNG-24 can produce 16.7 million colors.
The downside is the PNG file sizes tend to be larger relative to other image file types because of all this data. These images can contain up to 16.8 million colors, which is substantially larger than PNG8. I like this type of file, because of its color range and the transparency.
JPG vs. PNG
In general, PNG 24 is a better format to use than PNG 8, but there are some cases where PNG 8 can be useful. However, these high quality images come at a higher price because they take up more storage space How to implement linear search and binary search algorithm in JavaScript on your computer’s hard drive . You may want a bit more detail than this statement – perhaps explaining bit-depth… Currently the system auto-tagged this a s a low-quality post due to extreme brevity.
JPEG is good for photography, but for precise images with repeating blocks of color png will be more efficient. PNG24 doesn’t usually compress as well as JPG so unless you need transparency in a complex image it’s probably not the best choice.

Unfortunately PNG-24 files will still be bigger than JPEGs , and GIFs/PNG-8s , so you still need to consider if you really want to use one. PNG-24 supports the alpha translucent transition effect, that is, it can perfectly present the gradient transition from opaque to completely transparent. PNG 8 works best for small graphics which does not require more color details and PNG 24 is best for web photos and detailed images. It also offers a really good pixel to pixel representation of the screen. We can use PNG for photos that have line art, drawing and illustrations.
SVGs are also unique because unlike the image formats we’ve covered thus far, they create vector images. This means the images are infinitely scaleable and look good at all resolutions. Which make them great at adapting to different devices.
The best part about PNG 24 is that it preserves the color variations, for example, better gradients and prevents banding as well. Considered best for line arts, basic graphics etc. but it gives the file extra size which is not even necessary. In case you have very complex graphics and photos that require extra detail retentions then PNG 24 is the best choice you made. You can put either type on an HTML page and no, this won’t cause an error; the files should all be named with the “.png” extension and referred to that way in your HTML. I think PNG24 was always OK on Internet Explorer because PNG24 is either opaque or has GIF-like single-color transparency conveyed via a PNG tRNS chunk.
What Is PNG?
PNG, JPEG, and GIF are the three most commonly used image formats in daily contact. Almost all pictures on Internet pages are in these three formats. Dynamic images use GIF, and static images use PNG and JPEG. PNG 8 supports a single-bit transparency channel and PNG 24 aims to support the transition from opaque transparency. PNG 24 has a lossless compression capability whereas.
This will drastically reduce its file size, and you can do it with little-to-no apparent loss in quality. Because the PNG 8 format is designed for displaying images on the web, it typically doesn’t lose too much data and results in smaller file size. The PNG 8 format is also ideal for images that have a lot of text or sharp edges, as these types of images tend to compress well. This makes it an ideal choice for images that need to be displayed on the web, as it results in smaller file sizes than many other image formats. These files are larger than JPEG files and supports multilevel of transparency. PNG 24 is quite similar to PNG 8 but supports 16 million colors.
Understanding Digital Image Formats
The actual test found that the same picture, PNG-8 format has a greater compression rate than GIF. In addition, the number of colors can be set as small as possible without affecting the effect of the picture, so that the file will be smaller. PNG 24 uses index transparency in which you can apply matte color. This effect is so good as it gives an illusion of very smooth transparency along with the curves of the graphic. While making image with fully transparent background in PNG-8, the outline of the image looks prominent with little white bits.
- For images with a large number of colors, PNG 24 is the best option, while for images with small text or limited color palettes, PNG 8 may be a better choice.
- Which make them great at adapting to different devices.
- If you’re a site admin and you enable SVGs but your site’s authors and contributors aren’t aware of the risks, they could upload compromised SVG files without knowing.
- But there is also a subtler but still noticeable difference in quality between the two levels of PNG files.
You can open PNG files with several editing software programs. You won’t have any compatibility challenges with CorelDRAW when opening and viewing the PNG files.

PNG-24 is great for basic graphics, line-art, logos, etc., but you will have an unnecessary larger file size then needed. If you have more complex graphics or photos which require more detail retention, PNG-24 is a great choice. It can handle up to 256 colors, similar to GIF, and uses a lossless compression method. You will receive a low file size similar to GIF, approximately 10-30% smaller than other bitmap formats like JPG. If you’re creating an image with small text, a 256-color palette may be sufficient because the PNG 8 image will contain few colors.
But in PNG-24 the outline is gone and looks perfect. Transparency in PNG-24 is greater and cleaner than PNG-8. The “8-bit” sample image does not use the full 8 bits of transparency that the PNG format allows. PNG-8 is “lossless” too assuming you started with only 256 colours, … And PNG-24 would be “lossy” if you started with more than 16 million colours.
