This online utility lets you optimize GIF files and make them use less computer memory. You can optimize the transparency of a GIF, the quantizer sample radius, and skip every other frame. You can apply just one of these optimization methods or all of them together. You can see the result of optimization in your browser and download the optimized GIF file.

This is a browser-based program that optimizes GIF animations. Optimizing a GIF has many benefits – it uses less computer memory and loads much faster in the browser because there is less data to decode. There are several optimization techniques that we have implemented: transparency optimization, quantizer optimization, and frame-drop optimization. The transparency optimization compares pixels frame by frame. If the pixels in the next frame are the same (or very similar) to the pixels in the current frame, then they are made transparent in the next frame and as a result, they are skipped. Pixel similarity is defined via the threshold option. Usually, it is sufficient to enter a small similarity threshold value of 1% - 5% to obtain good optimization results. The quantizer optimization changes the pixel sampling radius of the quantizer. A larger sampling radius introduces tiny errors in the quantizer that leads to better optimization. This method is less efficient than transparency optimization but a value of 10 - 30 pixels creates visible a result. The skip-frame optimization changes the number of frames in a GIF. You can skip every 2nd, 3rd, 4th, or nth frame starting from any frame. You can also delete specific frames that you enter. For example, "1, 3, 6", which means skip frames one, three, and six, or "2-10", which means skip all frames from the second to the tenth. When skipping frames, the duration of the GIF does not change because the optimizer increases frame delays of the remaining frames to preserve the original GIF duration. This optimization method is very effective. If you skip every second frame, the GIF file size can be reduced by 40%. You can enable or disable each of the optimization methods in the options. You can use one of the methods or multiple methods at once. Our program lets you immediately see the result of transparency and frame skip optimization methods in the browser's GIF preview windows. The size of the new GIF file can be seen in the options by clicking the "save as" and "download" buttons. Coming soon, we'll also be adding other interesting optimization techniques: optimizing by reducing the color palette to fewer colors (for example, from 256 colors to 32), optimizing via dithering, optimizing by the GIF disposal method, optimizing by creating partial frames with modified x, y, width, height arguments, optimizing by dropping repeated frames, optimizing by using a lossy GIF compression algorithm, and optimizing by dropping local color tables and using only the global color table.

In this example, we optimize a tea pouring GIF using the transparency optimization method. We activate the option "Optimize Transparency" and enter "1%" in the transparency match percentage field. This means that pixels that are 1% similar to the pixels of the first frame become transparent in the following frames. As a result of the optimization, the original 482.05kb GIF is turned into a 371.48kb GIF. (Source: Pexels.)
In this example, we optimize a bunny GIF using two methods at once – the "Optimize Transparency" and "Optimize Quantizer" methods. For the transparency, we use the fuzzy color threshold of 5% and for the quantizer, we use a radius of 10 pixels. These two methods combined make the output GIF size almost 4 times smaller. The old GIF size is 255.88kb and the new one is just 66.34kb. (Source: Pexels.)
This example optimizes a blooming flower animation by skipping animation frames. It drops every second frame starting from the second frame. That is, it drops 2nd, 4th, 6th, 8th, 10th, 12th, 14th frame, leaving frames 1st, 3rd, 5th, 7th, 9th, 11th, 13th, 15th. The total number of frames and the framerate of the animation is reduced by two, however, the total playing time of the GIF remains the same. This optimization method reduces the GIF size by 40%, from 723.46kb to 488.49kb. (Source: Pexels.)
