Frequently Asked Questions
What does the PDF validator check?
Our validator checks PDF structure integrity, verifies the file is not corrupted, validates internal object references, checks for JavaScript or suspicious content, and provides details about the document's metadata, fonts, images, and security settings.
Is my PDF file stored after validation?
No. Your PDF is processed in memory and immediately discarded after validation. Only the extracted metadata is stored so you can review the results later via the share link.
What is the maximum file size?
You can validate PDF files up to 100 MB. For larger files, consider optimizing them first using our PDF optimizer tool.
Does it check for PDF/A compliance?
The validator identifies PDF version and checks for tagged content, embedded fonts, and other indicators of standards compliance. For a full PDF/A conformance report we recommend also checking with an industry-standard tool like veraPDF.
