PDF Repair — Free, No Upload, Browser-Based

PDF Repair attempts to fix corrupted or malformed PDF files by reloading them with a lenient parser and re-serialising the result into a clean, standards-conformant byte stream. The entire process runs in your browser — your file is never uploaded to any server. Works best on PDFs with broken cross-reference tables, invalid object headers, or spurious encryption flags.
