PDF Spell Checker
Inspect PDF document text for spelling errors, review corrections, and generate a cleaned document.
Extracted words are analyzed against client-side dictionaries in browser memory. Document contents and custom words remain strictly private.
The FileTools PDF Spell Checker extracts text streams from PDF documents, detects spelling mistakes, grammatical typos, and vocabulary errors, and organizes them in a page-by-page diagnostic dashboard. Review detected issues with instant correction suggestions, ignore domain-specific acronyms and technical terms, and copy corrected text or export diagnostic summaries without cloud uploads.
