Try LintPDF preflight

Drop a PDF in. We scan it for safety, hand the bytes to codex-pdf to extract structured facts, then LintPDF reads those facts and flags preflight issues — all rendered next to a branded Loupe viewer.

Files cap at 50.0 MiB and auto-delete after 15 minutes.

Findings + codex extract

LintPDF preflight findings (against the default profile) and the codex-pdf structured extract appear here side-by-side once a PDF is uploaded.

Branded Loupe viewer

The PDF renders here next to the analysis — separations, TAC heatmap, color picker, layers, and densitometer all wired against the codex sidecar.
