RIOT does surprisingly well, shredding GIF sizes by 40%.The main reason why your GIFs load so slowly is likely because you have too many frames in the GIF. RIOT is more about reducing the number of colours in your image, re-encoding JPEGs with a lower quality value, and so on. A clean and clear interface makes it easy to compress individual GIF, PNG or JPG images and compare the results while a batch interface processes multiple files at very high speeds. RIOT is a free tool for image conversion. You can do better elsewhere with individual tools, but if you just want a single, simple Mac-based tool, which can handle GIFs, JPEGs and PNG files, this tool is the way to go. As a result it won’t cut file sizes by quite as much as some of the competition, but at least you don’t have to worry about any loss in image quality. The program is all about lossless compression – removing comments, colour profiles and so on – rather than re-encoding or reducing the number of colours. ImageOptim is a Mac tool that optimises GIF, JPEG and PNG images by acting as a front end for a host of other applications. The originals are sent to the Recycle Bin so remain recoverable. This simplicity has a downside, as your source files are replaced by the program. 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. PNG’s DEFLATE algorithm achieves better compression than GIF’s LZW algorithm.PNG’s ancillary data sections support compression allowing their overall size to be reduced.The size of PNG palette entries can be smaller than the corresponding GIF palette entries on images with less than 256 colors.Let’s name a few to get a better picture: The PNG format was defined 10 years after the GIF format, allowing PNG images address some of the flaws that GIF was facing. PNG images are also a lossless image format that very closely mirrors GIF images. Pay close attention, because this is where the PNG format sweeps in and takes the win. GIF comments, metadata, and Application Extension sections don’t contribute to the rendering of the graphic data. Being an 8 bit-depth image format it would have disappeared from the web after the introduction of the JPEG and PNG file formats, but GIF is still a favored web file format thanks to its frame animation feature. GIF is the standard format for compressing images with large areas of solid colors and crisp details like those in line art, logos, or type. GIF is a lossless image format, which features the ability contain multiple graphic images inside of a single file.
