Validate and auto-fix every file your customers upload, before a bad file becomes a bad order
Bad uploads cost print stores reprints, refunds and support emails. Filecheck replaces your upload form with one that checks every file on the spot: it validates PDFs, images and documents in seconds, auto-fixes common problems like missing bleed, low resolution and RGB color instead of rejecting the shopper, and shows a visual proof for color and crop sign-off. Add to cart stays locked until the file passes the rules you set, so unprintable files don't land in your orders.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows Filecheck: Upload Preflight on a store, it is there.
