Preflights You
Won't Hate.
Detection-only preflight engine. Inspect color spaces, fonts, images, transparency, page geometry, packaging geometry & barcodes — without ever touching a single byte.
Everything you need for PDF preflight
Built for web-to-print platforms, packaging houses, and publishing workflows that demand precision without compromise.
Detection-Only
LintPDF finds problems — it never modifies your files. Your originals stay untouched, byte for byte. Zero risk of file damage, every time.
API-First
One POST to Submit your file. One GET for the Report. JSON, XML, or a white-labeled PDF report with your logo. That's the entire integration.
500+ Engine Checks + PDF/X-4 Suite
Fonts, color spaces, images, transparency, overprint, page geometry, ink coverage, packaging geometry, barcode grading, plus a dedicated 91-check PDF/X-4 conformance suite (ISO 15930-7) — every detail that matters for print production.
Bring Your Own Preflight
Already running PitStop, callas pdfToolbox, or Adobe Acrobat Preflight? Send the PDF plus the upstream XML/JSON report. LintPDF parses the findings, renders them in the viewer, and mints share links — no double-checking.
White Label + Anonymous Output
Maintain one or more BrandProfiles per tenant — pick a default, override per job or share-link, or strip everything with anonymous mode. Anonymous mode sanitizes PDF metadata, uses a neutral filename, and renders zero LintPDF marks. Perfect for brokers handing reports to distributors.
Rulesets & Conditional Rules
Pre-built profiles for GWG Sheetfed, GWG Digital, PDF/X-1a, PDF/X-3, PDF/X-4, PDF/A, and Packaging workflows. Conditional rule engine lets you build dynamic Rulesets with the exact logic you need.
Webhooks
Webhook callbacks fire when your file finishes processing. Get notified the instant a Report is ready — no polling, no waiting, no wasted cycles.
Non-PDF Input Support
Submit EPS, PostScript, TIFF, JPEG, PNG, and PDF-compatible AI files. LintPDF converts them to PDF internally and runs the full Check suite.
…and more
Self-service onboarding, priority queues, conditional rule engines, viewer annotations, AI inspections, and more ship across our plans.
Open source
One family. Four repos. Pick the piece you need.
The print-prepress stack split into focused, replaceable components — facts extraction, preflight engine, embeddable viewer, and a metadata assay tool. Use one, use all four, or vendor only the parts that fit your pipeline.
