Technical details and limitations
One of the primary limitations of GIFs lies in their color representation. Constrained by a palette of only 256 colors, these images often struggle to accurately depict the richness and subtlety of colors, particularly evident in photographs and images with complex color gradients. This restricted color range frequently leads to a noticeable degradation in image quality, as the format struggles to render detailed or realistic visuals.
The lossless compression algorithm employed by GIFs, known as LZW, while revolutionary at its inception, now pales compared to modern compression algorithms used in more recent image formats. This dated compression technique contributes to larger file sizes, diminishing the format’s practicality in an era where data optimization and bandwidth conservation are very important.
As technology advances and demands for higher-quality visual content, the limitations of the GIF format become very visible. The inability to accurately portray a wide spectrum of colors and the inefficient compression technique hinder its effectiveness in conveying details and nuances.
While animated GIFs continue to hold a nostalgic charm and retain utility in certain contexts, their technical restrictions have spurred the evolution and adoption of newer formats better equipped to handle the demands of modern multimedia content creation and consumption.
For instance, formats like WebP and AVIF offer superior color depth, better compression methods, and improved support for animations, surpassing the limitations that the .gif file format inherently carries, as we’ll see below.

How to handle large animated GIFs online?
When dealing with large GIF files (several MBs), you have a few options:
Reduce dimensions
One approach involves reducing the dimensions in pixels of these larger GIFs.
Online tools like ShortPixel offer a convenient and effective means to perform this operation. Users can modify the resolution of the file before compression, reducing its dimensions while maintaining a proportional aspect ratio.
This reduction often results in a smaller file size, making the GIF more manageable for compression, online sharing, and web embedding.
Reduce frame count
Lessening the number of frames in the animation can significantly reduce file size.
Tools for this purpose are available both online and as Windows applications.
For example, by using EZGIF, the frame drop feature offers an efficient way to reduce the frame rate and file size of GIFs by selectively removing every second, third, or fourth frame.
This option is particularly beneficial for lengthy GIFs with high frame rates, allowing for a more manageable file size without significantly impacting the overall viewing experience.
Also, there’s an option to eliminate only duplicate frames. This identifies and removes consecutive frames that are identical or extremely similar, combining their display times.
This approach might not be needed for most GIFs, but it’s highly effective in cases where frame redundancy is significant. It helps create smoother, more efficient animations while reducing unnecessary file size.
What if the GIFs are still too large after compression?
GIF files, specifically animated ones, while popular, can sometimes remain too large even after compression.
In such cases, alternative formats like WebP and AVIF can be highly effective in reducing file sizes without compromising the quality of the animation.
Convert GIF to WebP
WebP is an image format developed by Google that supports animation and is widely supported by modern browsers, encompassing approximately 98.5% of current browser usage statistics.
