About This Tool
Preflight PDF documents with our free online print verification tool. Check for common printing issues including image resolution, font embedding, color spaces, and page dimensions before sending to print production.
Scan documents for low-resolution images, missing fonts, RGB colors in CMYK workflows, oversized pages, and other issues that cause print problems. Receive a report identifying potential issues with recommendations for fixes.
All preflight checking happens locally in your web browser. Your documents never upload to external servers, ensuring privacy for print projects, marketing materials, and documents undergoing production verification.
Perfect for catching print issues before submitting to print shops, quality-checking documents in production workflows, verifying files meet print requirements, or training on print preparation best practices. Note: Basic checks only—for production work, use full preflight software like Adobe Acrobat Pro's Preflight panel. Works with all PDF files.
