Frequently asked questions
Can PDFWix automate per-order document generation?
Yes. The developer API generates PDFs from HTML, merges supplier docs, and adds watermarks programmatically. See /developers for the OpenAPI spec and a 250-ops/month free tier.
Is it safe to compress shipping labels?
Yes. Use the Low compression preset to keep barcode contrast high — Recommended works for most labels but barcode scanners are picky about contrast at high compression.
Does PDFWix support customs paperwork?
Yes. Merge PDF bundles commercial invoice, packing list and certificate of origin. Sign PDF handles supplier and forwarder signatures. AES-256 protection covers transmission.
