You’re also not limited to only compressing PDFs you can reduce the file size of other document types, like MS Office files, JPG, PNG, GIF, and TIFF. Yes! All of our tools, including our tool to compress files, are free to use with certain limitations. Is this document compression tool free to use?.Information about the new size of the GIF file appears when you click the 'Save as' and 'Download' buttons. Also in the options, you can find the main information about the original and compressed GIFs. Turn on the animation mode in the options to run all the frames from the first to the last. All changes to the GIF (except for the quantizer compression) are immediately visible in the interactive GIF player. It changes how the color palette is distributed throughout a frame and with a larger sampling radius, it can produce a slight reduction of size.

The last compression method changes the color quantizer's sampling interval. The higher the percentage, the more noise appears in the GIF and the greater the compression. In the options, you can set the percentage of similar pixel matching. For example, if all frames of a GIF have the same blue background, then it can be drawn only on the first frame and on the remaining frames that area can be left transparent. This trick consists of comparing frames that overlap one another and making the areas that are similar in color transparent. If you don't want to change the number of frames in the GIF, then you can compress the animation using a smart transparency trick. For example, you can list the frames to be deleted separated by commas '4, 6, 9' or enter a frame interval '3-10'. You can also get rid of specific frames that you don't need or that don't contain any movement. In the options, you can set the distance between the frames to delete and the starting frame of deletion. You can delete every second, third, fourth, or any other periodic frame. This compression method reduces the file size by 40% - 50% because the GIF has half of its frames removed. For example, if the original GIF shows 20 frames per second and you delete every second frame, then the animation will be shown at a speed of 10 frames per second. The most popular and effective compression method is to reduce the GIF framerate. Strong compression, using several techniques, can reduce the file size several times. With minimal effort, you can get a GIF file that is 30% - 50% smaller. Compression is achieved by introducing tiny noise and errors in the animation or by reducing the number of frames in the animation. This is a browser-based program that compresses the size of a GIF file.
