How does the Repair Corrupted PDF work?

Sometimes a PDF gets corrupted — partial download, an interrupted save, a flaky USB stick, or a tool that wrote a malformed cross-reference table. The result: a PDF that won't open, or opens with errors. This tool runs qpdf's repair pass: re-parse the document, rebuild the cross-reference table, disable object streams (the most common source of corruption), and re-emit a clean, linearised PDF. Many "broken" PDFs come back working perfectly; severely damaged ones may still fail or come back missing pages. Files are processed and deleted right after you download.

🔒 Security & Privacy

Files are encrypted in transit and processed on a secure server. Your file is automatically deleted right after you download — we never store your documents.

📱 Use it on any device

Works in any modern browser — Mac, Windows, Linux, iPhone, Android, and tablets. No installation, no app to download. Just open the page and start.

⚡ Quick & easy

Drag, drop, click. Most files process in seconds, not minutes. No watermarks added to your output, no per-day limits, and the tool always shows the result before asking you to download.

🎁 Always free, no signup

Free to use, every time. No account creation, no email required, no “trial” that converts to a paid plan. We make money from ads so you don’t have to pay.
