How To Upload Large Gifs

The author's views are entirely his or her own (excluding the unlikely event of hypnosis) and may non e'er reflect the views of Moz.

The GIF (Yardraphics Interchange Format) format was originally developed in 1987. Debuted by Steve Wilhite of Compuserve, GIFs improved on the black-and-white images in utilise during that time past allowing the use of 256 colors while maintaining a compressed format that could still be loaded by those utilizing slow modems. Furthermore, web developers and designers could create animations via timed delays. And to this day, footling has inverse regarding GIFs.

Due to its simplicity, the widespread support for this format, and the ease with which it can be used to stream video clips, the GIF format is the oldest file format still commonly used today. This frame animation feature of GIFs ensures that the format remains popular, despite the rise of JPEG and PNG images.

In spite of their popularity and ubiquitousness on the Internet (especially with regards to animated GIFs), GIFs are not the about performant of image options. If yous are using GIFs on your sites, it's important that you take care to optimize your GIFs so that they do not create too much overhead.

This article will cover ways to optimize your GIFs, both static and animated, and volition offering an excellent culling you can employ to eliminate the page bloat resulting from use of GIFs equally animation.

Why should you optimize your GIFs?

Performance matters when it comes to designing your web pages, and GIFs are not the most performant of epitome options. While they are excellent for capturing your user's attending and are universally liked for providing short bursts of information in an entertaining way, GIFs were not designed for blitheness (despite them being commonly used for such). As such, usage of GIFs leads to heavy page weights and poor user experiences resulting from tiresome page load speeds.

How to improve the performance of your site while using GIFs

In this department, nosotros'll comprehend several means you can improve the functioning of your site with regards to using GIFs. We'll start dig into ways to handle static GIFs, and we'll end past discussing ways to minimize the overhead resulting from animated GIFs.

There are 2 methods for compressing images:

One of the principal methods for optimizing GIFs is to compress them. There are 2 methods of compression that are unremarkably used:

• Lossy compression: Lossy pinch removes some of the data from the original file, resulting in an image with a reduced file size. However, every time you save the file later pinch, the quality of the graphic degrades somewhat, which can result in a fuzzy, pixelated paradigm over time.
• Lossless pinch: Lossless compression preserves all of the information from the original file, which means that the compressed file can exist uncompressed to gain the original file. While your file size remains larger than if you had used lossy compression, your image'south quality does not degrade over time.

Afterwards on in this post, we'll comprehend the affect of both types of optimization on GIFs.

Improve the operation of sites that are using static GIFs by converting to PNG.

The easiest way to improve the functioning of your site is to render your paradigm using the PNG format instead of the GIF format. While the two formats are very like in terms of existence practiced choices for displaying unproblematic graphics, PNG files have the advantage of beingness able to compress to a size 5–25% smaller than the equivalent GIF file. GIFs were originally created to use a lossless compression technique chosen the Lempel-Ziv-Welch (LZW) algorithm, which was defined in the 1970s. However, modern compression techniques are much more than performant than LZW, and you can have advantage of this by using formats that use these techniques, such as PNGs.

Such file format conversions are pretty easy to do, and there are an abundance of software options you tin can choose from, including gratis spider web-based utilities such as the ones from Film.io and Convertio.

Improve the performance of sites that are using animated GIFs one of two ways:

Animated GIFs, while extremely pop, tin exist huge files that crave lengthy load times. For example, a GIF that is just a few seconds long can be a few megabytes in size. To improve the performance of your site, use one of the post-obit techniques:

• Lossy optimization
• Converting your animated GIF to a HTML5 video

Lossy optimization on animated GIFs

Considering the vast bulk of data comprising animated GIFs is graphical information, and because lossless optimizations cannot change graphical data, you take only i viable pick when it comes to optimizing an blithe GIF across the bare minimum: lossy optimization techniques.

Lossy optimizations work because the human middle does not practise a very good job at distinguishing between subtle changes in color. For example, an image might contain thousands of shades of one colour, with one pixel showing as only slightly dissimilar from the ones next to it. Because your eye won't be able to differentiate between the ii shades, the image file can hands be manipulated: 1 of the colors replaces the other, making the file smaller.

Because animated GIFs are essentially a serial of individual GIFs, you lot tin utilize these techniques to decrease the size of your blithe file. Past making each individual file smaller, your overall file is smaller as well. One mode y'all can do this is by utilizing a unproblematic software suite that can automatically perform such compressions (such as a modified version of gifsicle).

Converting animated GIFs to HTML5 videos

While you can minimize the size of an blithe GIF, you lot may withal end upward with a file that is larger than it needs to be. GIFs were never intended to store video, and what is now considered animation is actually the result of an endeavour to reduce overhead on the storage and transmission of multiple images that share identical metadata. Today, notwithstanding, we have another pick that could potentially make your GIFs upwards to 95% smaller: converting your blithe GIFs to HTML5 video.

HTML5 video is a grab-all term for a mod web browser's ability to play video content using the <video> tag without needing to utilize external plugins. When this characteristic was first released in 2009, there was a lot of contend over how such videos would be stored and how they would exist encoded. Today, though, the accustomed standard is an H.264-encoded video stored in an MP4 container file (which, for simplicity's sake, we'll refer to as an MP4 video from hither on out). In addition to looking a lot better due to its being designed to stream video, MP4 files are much smaller as well:

Over 90% of mod web browsers support MP4 videos.

There are many ways to convert your animated GIF to MP4, such as the popular open-source command-line tool ffmpeg and the web-based utility Cloud Convert. Using the latter, you can run into the file size savings possible by making the conversion.

Here'due south the original animated GIF:

Hither is the MP4 video that's created from the GIF:

Looking at the sizes of the files, nosotros see that the original was 100 KB. By converting the GIF to MP4, nosotros end up with a file that is simply 23 KB, which is 75% smaller:

Conclusion

GIFs are the oldest file format nevertheless normally used today due to their simplicity, most-universal back up, and ability to be used as animation. Despite these positive features, GIFs tend to be large files, resulting in page bloat that can negatively impact the performance of your webpages and pb to poor user experiences. As such, y'all should consider serious optimization of static GIFs, moving away from blithe GIFs, and implementing video clips using more than modernistic techniques such as HTML5/MP4 videos.
