(If you're seeing identical images here - let me know! It means there's a browser out there that is handling GIFs differently to the big browsers.) Source of the Problem The 0-delay red squares are visible when rendering. The colourful GIF only renders small portions at a time. The value can be set from 0 (no delay) to 0xffff (roughly a 10 minute delay). Specifically, it's the number of hundredths of a second to wait before continuing to the next frame. Now before each image frame, an optional "delay" value can be set which determines how long that frame should be shown before moving on to the next one. In the current version of the GIF format (89a), transparency and animation features are available. Each frame could reference a different 256-colour palette, so an image could be created using more than 256 distinct colours. In the first version of the GIF format (87a), multiple image frames (of varying size and position) would be overlaid on top of each other to create a single resulting image.

Otherwise, my condolences, and please disregard this message.) Me when GIFs are too slow GIF Features (Disclaimer: If you're from a distant utopian future where this isn't a problem any more, a few of the example GIFs in this article won't make much sense. If you want to learn a bit more about GIFs, exactly why this edge case happens, and some thoughts on how to improve things, keep reading! If you're here because you want to fix your GIF and want the quick answer, the solution is: set your frame delay to 20ms instead of 10ms. But when you view the resulting GIF, it's playing much slower than intended, and there are definitely GIFs that play faster than this one. The GIF editor you're using lets you set a frame duration / delay, so you set it to the lowest possible value for maximum shakage. You’ll find that, when you convert the file, it will be considerably better optimized for use on the web as well.You're trying to create a violently-shaking GIF for comedic purposes ( ). Once you convert the file to MP4 you can use an MP4 editor, such as Lightworks, to edit and transform the file. It’s a broad service that allows converting files between many different formats. Converting a GIF to MP4 makes your file significantly smaller and allows you to edit it as a video rather than a collection of frames.Ī very quick and easy-to-use platform for converting GIFs to MP4 files is Convertio. MP4 is the preferred format for videos in most browsers. It may seem counterintuitive, but sometimes the best way to approach this problem is to step away from the GIF format altogether. Keep in mind that the removed frames will reduce the quality of the GIF. This will speed up the GIF significantly but it will have an even greater effect on the size of the file. You can choose to cut out one frame in every two or four frames and you should use one of these two options for consistency. Any decent GIF editing tool, such as Ezgif listed above, will allow you to cut frames out of the file. Again, there is very little merit to manually removing frames. You can still do that, but there are many good editors that can ease the process.Īnother way to speed up a GIF and optimize it is to cut out superfluous frames. Since a GIF is a collection of frames, normally you would have to resize every frame in the animation. This is a very effective way to shave size from a GIF, though, and make it more web-friendly. Resize Your GIFĪ resized GIF may load faster but it won’t be faster. Use any number between 1 and 99 percent to slow the GIF down. If you need the GIF to be slower, you can do so too. You can continue to change the speed as you want. Click on the “Save” button to download your image into your default downloads folder.Click on “Change Speed!” Your output image will be displayed below.Choose a percent by which you want to increase the speed and enter it in the text box below.When you find the file you’d like to use, click on the “Upload!” button. Click the “Choose File” button and use the file explorer to find your image or paste a URL in the search bar.
