Validate PDF

Check whether a PDF passes structural validation.

Why use Validate PDF?

Broken PDFs fail silently in portals until the deadline hits. Structural validation gives you a fast sanity check before you upload to courts, insurers, or print vendors. PDFBaba returns JSON diagnostics rather than a pretty file—this is intentionally nerdy and precise. There is no signup wall, and uploads are short-lived. If validation fails, try Repair PDF next, then re-validate. Keep originals until you confirm the repaired file opens everywhere you need.

Supported files & limits

One PDF for structural validation. The default upload limit is 100MB per file; administrators can raise or lower this via server configuration. You receive JSON diagnostics instead of a converted download.

Privacy & data retention

PDFBaba is built for quick tasks: your uploads and generated downloads are kept only long enough to process your request and are automatically deleted after about one hour. We do not require signup for these tools, and we do not use your documents to train AI models. For full details on cookies, analytics, and legal terms, read our Privacy Policy.
