animated, seamless repeatable background patterns for pdf
The Portable Document Format (PDF) (redundantly: PDF format) is a file format developed by Adobe in the 1990s to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it. PDF was standardized as ISO 32000 in 2008, and no longer requires any royalties for its implementation.Today, PDF files may contain a variety of content besides flat text and graphics including logical structuring elements, interactive elements such as annotations and form-fields, layers, rich media (including video content) and three dimensional objects using U3D or PRC, and various other data formats. The PDF specification also provides for encryption and digital signatures, file attachments and metadata to enable workflows requiring these features.

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:
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.
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.
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.
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.
