![]() Right, with all that out of the way, let's begin! (If this happens you can view an old version of the GIF here). I don't think I can fix that as it appears to be the dev.to caching pointing to the old image! The use case is for email marketing, where we cannot use JavaScript to create a countdown and we cannot even use video (reliably), so an animated GIF is our only option!ĭownloading a 4mb GIF to display a countdown timer would be a massive mistake for performance, use JavaScript instead (plus it is waaaay easier)!įinally - if you return to the page the image might not show for you. Obviously it isn't one massive file (it would need 26 MILLION frames! so it would be quite large) so how did I do it?Īs pointed out in a comment by this is a lot of effort for a countdown timer! In fact you can check for the accuracy of my timer here, it should be within a minute when you first load this page! I think it is pretty cool that for the next 200+ days (at time of writing) that Gif will always be within one or two minutes of an actual countdown timer! If the GIF doesn't load you can view an old version of the GIF here. You can also find more information about the GIF video in the information section, and you can download the GIF with a timer under the output preview field.The GIF below is counting down to the 3rd January 2022 at 09:00. When the timer is added, you can examine individual GIF frames via the "Frozen Timer Mode" option or see the entire animation with a timer on all frames via the "Running Timer Mode" option. You can also change the timer font, the size of timer digits, the line-height (in case you use a multi-line timer), and choose a color for the timer and its background. The position of the timer can be set in the options or adjusted directly in the preview field by moving the timer rectangle with the mouse. If you don't use the "%t" and "%f" parameters, then you can simply overlay any text over the GIF. For example, the string "time: %t sec(s), frame: %f" will give the result "time: 1 sec(s), frame: 4". You can also mix these parameters with regular text. These parameters are substituted with the timer value and the current frame number value. The timer text and format can be set via the format-string parameters "%t" and "%f". The first frame shows the entire running time of a GIF and each subsequent frame decreases this value towards 0.00s. In this mode, the timestamps are added in reverse order. Additionally, there's an option to enable a countdown timer. The timer precision can be 20ms, 50ms, 100ms, 200ms, 500ms, or 1 second. This mode increases the number of frames in the GIF and achieves accurate timing for any timer interval. If there is no suitable frame for a timer value, it injects an additional frame in the GIF with this timer value. This problem is easily solved with the second – "Uniform Timer" mode. The timer value 0.05s (50ms) will be skipped because there is no frame at 0.05s that could display it. For example, if a GIF has a frame delay of 0.1s (100ms) and the timer accuracy is 50ms, then the first frame will be timestamped at 0.00s and the second at 0.10s. ![]() The disadvantage of this timer mode is that if a frame is displayed on the screen for a longer time, then smaller resolution timer values will be skipped. This mode does not change the number of frames of the original GIF. This mode simply prints the current time of each frame that's calculated from the original frame delay values (each frame in a GIF has an associated delay that indicates how long a frame should be displayed on the screen). The first is the "Frame Delay Timer" mode. It displays the running time of a GIF in seconds or milliseconds. This browser-based program draws a digital timer on a GIF animation.
