PDF tool

PDF Validator

Check whether a PDF opens correctly: structure, encryption, pages and text layer — reported honestly, no fake repair.

100% local — files never leave your deviceProcessed in your browser

How it works

Upload the suspicious or important PDF.
Validation runs structure parsing, encryption detection and a text-layer sample scan.
Read the report — each finding says OK, warning or failed with context.

Good to know

The tool diagnoses; it does not repair. Automated “repair” frequently makes damaged PDFs worse, so we don’t pretend otherwise.
Every step runs locally in your browser using Web Workers — your file is never uploaded to any server.
