To make a digital download to sell, you will need to: Choose a file format. The most common file formats for digital downloads are PDF, MP3, and ZIP. Compress your files. If you are selling multiple files, you will need to compress them into a single file. This will make it easier for your customers to download and use your product. Set a price. Once you have compressed your files, you will need to set a price. Consider the value of your product, the cost of production, and the competition. Create a download page. Once you have set a price, you will need to create a download page. This page should include a link to your product, as well as instructions on how to download and use it. Promote your product. Once you have created a download page, you will need to promote your product. This could involve creating an eCommerce website, using social media, or running paid advertising.
