![]() ![]() The program has one of the most straightforward interfaces here: drag and drop your images onto FileOptimizer, right-click, choose Optimize and that’s it. Checking these 3 free tools out is more than advisable FileOptimizerįileOptimizer can compress JPG, GIF and PNG images, and even executable files, archives, Microsoft Office documents and PDF files. It’s also important to note that there are some great tools out there to optimize the weight of GIF files. Converting to PNG is a nice, universal way to do this. There are numerous aspects of the GIF image format which allow for lossless optimizations to reduce file size while maintaining image quality. Minimize what is changing between animation frames, reducing the size different Graphic Image Data sections. Combine or generalize local palette information in individual Graphic Image Data sections into the Global Color Table.Ĩ. Remove metadata, or unused palette entries from a GIF and write a better optimized GIF.Ħ. It may give huge file size reduction in some cases when images have large, static areas.ĥ. The results variate a lot on the nature of the image. Optimize Transparency – This option makes some unchanging parts of the frames transparent. Useful for gifs with a high frame rate.Ĥ. Remove every n frame – The frame drop option can remove every second, third, or fourth frame to reduce frame rate and, therefore, file size. ![]() It can reduce animated GIF file size by 30%-50% at a cost of some dithering/noise.ģ. Lossy GIF compression – Compresses GIF with Lossy GIF encoder which implements lossy LZW compression. ![]() Each gif frame can use up to 256 unique colors, and by reducing this number, you can achieve a smaller file size.Ģ. Color reduction – shrink gif file size by reducing the number of colors in each frame. This means the median savings of converting all GIFs to PNGs is 21.07%. The median size of the result PNG images was 5546 bytes. The median size of the GIF images was 6900 bytes. Comments, metadata, embedded thumbnails, Application Extensions, and other non-graphical information present in a GIF are not transferred over into the resulting PNG, shredding all the excessive data, resulting in a lighter image. Programs that convert from a GIF image to a PNG image focus only on on converting graphical data.
