One upload slot can turn three documents into a file-handling problem. First check what that particular form asks for. If it genuinely wants a combined packet, keep the requested pages in order and inspect the result before you upload.
This guide uses a fictional Drew Ski example. We created and checked the packet locally with Codex-authored Python; Claude Code and its PDF plugin were not run. The full guide and Markdown copy unlock with your email for access, not newsletter consent.
