If you're using a WordPress site, you can install the Optimus plugin to automatically optimize your PNG images as you upload them. Optimus offers users 2 ways to reduce PNG file size. The easiest way to reduce PNG file size if you're working with a number of images is to use an online tool, plugin, or script. Indexed-color allows you to save the image with upwards of 256 colors, and you can make this adjustment in most photo editors. If an image is in black and white or only has a few colors, such as with a logo, it's a good idea to save it with the lowest color option. Being saved with alpha means that the PNG also has transparency.Ī PNG file saved in Truecolor is going to have a larger file size than one that is saved as Grayscale or Indexed-color. PNGs can be saved as Grayscale, Truecolor, Indexed-color, Grayscale with alpha, and Truecolor with alpha. One of the most basic ways to cut down on a PNG's file size is to limit the number of colors that the image has. The good news is that there are a variety of methods and tools that can reduce the size of PNG files by anywhere from 10 to 80 percent depending on the tool and the image in question. Some image editors don't automatically reduce PNG file size for you, so you'll like need to make use of an optimization tool / service to reduce the image file size. When you're using them on a website or in an app, PNG files that haven't been optimized can dramatically increase load times. In some cases, just adding a few pixels of additional width to a PNG file can double the file size. There is one major downside to PNG files, and it is that the file size of this type of image can get large quite quickly. If you're unsure what the difference is between PNG and JPG files, consider reading our PNG vs JPG Images post. The ability to take advantage of transparency and lossless encoding make them a popular choice for web designers and web developers they are one of the most commonly used image file formats on the web along with JPG. With PNG files, you have the ability to take advantage of transparency, you can animate them, and you are able to save them without loss of color or quality. This can dramatically degrade the quality of the final output image since monitors are able to show upwards of 16.7 million colors. While GIF files are able to provide transparency, they're also limited to 256 colors. Google JPG lossy compression and PNG lossless compression for more information.PNG files are a high quality alternative to GIF files. PNG files use lossless compression where no data is lost. JPG files use lossy compression where data is lost.

Resample images to reduced resolutions with a graphics editor like the free IrfanView (simple to use) or GIMP (more powerful and much more difficult to use). LO is not a good image processor when compared with proper image processors. Do all image processing in an image editor before placing the image in the document.If the image will be viewed on screen, what is the screen resolution? A high definition 15.6" wide laptop screen typically has 1,366 pixels - there is no point in your image being higher resolutions than this. = 900 pixels wide for 300 dpi and 3 x 600 = 1800 pixels wide for 600 dpi Will be, say, 3 inches wide on paper and youĤ50 pixels wide for 150 dpi printing 3 x 300 Decide what resolution you require for the final document. A 6 million pixel image from a camera is typically 3,200 pixels wide which is usually far too many pixels for for most purposes.NEVER use JPG for graphics as it blurs edges and makes text very poor.ALWAYS use PNG (or TIF or GIF) for graphics (ie not photos - things like clip art, diagrams, anything with text etc).NEVER use PNG for photos as a PNG file will typically be 3x bigger than the JPG.NEVER copy and paste a photo into a document as LO does not know what format the original image was in and will (correctly) save it as a PNG to ensure no data loss.PNG files are already compressed and cannot be compressed further.
