Loading Patterns / Animated, Seamless Repeating Background Patterns in SVG / GIF / APNG

thunder Pattern

animated, seamless repeatable background patterns for thunder

Thunder is the sound caused by lightning. Depending on the distance from and nature of the lightning, it can range from a sharp, loud crack to a long, low rumble (brontide). The sudden increase in pressure and temperature from lightning produces rapid expansion of the air within and surrounding the path of a lightning strike. In turn, this expansion of air creates a sonic shock wave, often referred to as a "thunderclap" or "peal of thunder".

Usage

Animated repeating patterns can be used in various ways, such as in website background, or to fill HTML / SVG elements. You can also use them as slide / video background.

Here is an example of using animated pattern as background of an icon animation:

<div
  style="background:url(/your-pattern-url)">
  <img src="your-icon-url">
</div>

Formats

All patterns can be generated in SVG / APNG / GIF formats. PNG sequence or static PNG are also available. To choose the right format for yourself, you should check the compatibility and quality of these file format before using them.

GIF

Provides the best compatibility, while big in size and low in quality. supports only up to 256 colors at most.

Supported by all browsers, even by old browser such as IE5 or Netscape.

SVG

Gives the best quality and file size but is CPU-intensive to render. Animation is more likely to lag when browser is busy

Animated SVG is not supported by IE or Edge.

APNG

Provides similar quality to SVG and is supported by most modern browsers, including Microsoft Edge.

However, its file size is proportional to image size, and isn't supported by older browser like IE.

Loading Patterns

seamless repeatable patterns built for animation

Loading Patterns is loading.io's animated pattern generator that makes tiled images for using as texture, image pattern or in backgrounds of app, video or website. It can also be used to fill shapes, icons or progress bars.

Seamless Repeatable

All background patterns generated in loading.io are seamless repeatable, either in static or animated format.

This significantly reduces the size of animated image, and is perfect for looping as background tile in any place with variant size.

Vector-based Image

Tiles are all designed based on lossless vector image format SVG with the capability to generate to other formats including GIF, PNG/APNG and PNG sequence.

SVG format keeps the highest quality of images against resizing while also optimizes the file size and possibility for flexible retouching.

Animatable & Customizable

Loading.io empowers the background patterns with various types of animation which could be customized with loading.io's pattern editor.

All patterns are pre-designed but can still be customized according to your need.
