Yes, zines can be digital.
Digital zines can be created using a variety of software, such as Adobe InDesign, Adobe Illustrator, or Microsoft Publisher. These programs allow you to create layouts and designs that can be exported as PDFs, which can then be shared online or via email.
Digital zines can be distributed through a variety of channels, including email, social media, or through online marketplaces like Etsy or Big Cartel.
Another way to create digital zines is by using online platforms like Issuu, Joomag, FlipHTML5, and others, which allows to create and publish digital magazines, catalogs, and zines without the need of software installation.
Digital zines can also be interactive, with the use of hyperlinks, embedded videos, and other multimedia elements. They can also be created using a combination of text and images to create a more dynamic experience for the viewer.
It's worth mentioning that digital zines can also be printed, to create physical copies, and it's also important to keep in mind that digital zines may not have the same tactile experience as physical zines, but they have the advantage of being easily shareable and accessible to a wider audience.
