Filepad

Filepad is a free browser tool for people who sell digital downloads such as printables, planners, cut files and ebooks. Choose Etsy, Gumroad, Shopify or Payhip, add the files buyers will receive, and Filepad checks file count, size per file, accepted types and file-name rules, image pixels for 300 DPI prints, PDF page counts and what is inside a ZIP. Every finding comes with a next step, such as a clean file name to copy. When a listing has too many files, the ZIP packer sorts them into ZIPs that each stay under Etsy's 20 MB limit. Files never leave the browser and there is no account.
