About PDF Preflight

Printers reject files for problems invisible in a normal viewer — and discovering them on the press date is costly. ILikePdf PDF Preflight runs structural checks on your PDF locally and reports errors, warnings, and standards issues before you submit. Use it to audit files headed for print, publication, or third-party systems. The report is generated in your browser, so pre-press documents with sensitive content never leave your device.

How to preflight a PDF PDF Preflight

Step 1: Upload the PDF you want to inspect.

Step 2: The tool runs a set of structural checks locally.

Step 3: Review the report for errors, warnings, and standards issues.

Step 4: Drill into specific issues for details.

Step 5: Fix the flagged problems in your source file and re-check.

Common use cases for PDF Preflight

Verify PDFs before sending to a print shop.
Check documents for structural errors before publishing.
