Zevvo File Upload for WooCommerce

Zevvo File Upload for WooCommerce allows your customers to upload files directly on product pages and have those files automatically attached to their orders. Whether you run a print-on-demand store, a custom gift shop, or any business that needs customer-supplied files, Zevvo handles it securely and smoothly.

Built from the ground up for HPOS (High-Performance Order Storage) compatibility, it works with both the classic and block-based WooCommerce cart and checkout.
