Repair PDF

Try to recover content from damaged PDFs

About this tool

Recover content from a damaged or corrupted PDF. We first try to re-save the file using pdf-lib, which fixes some structural issues. If that fails, we fall back to rendering each page via pdf.js and rebuilding the document. Note: severely damaged files may not be recoverable in browser — server-side tools like Ghostscript are more powerful.
