If your PDF viewer says 'damaged' or 'cannot open', the file's body is often fine but its cross-reference table – the index that tells readers where each object sits – is broken. GekiPDF's repair tool rebuilds that table with Ghostscript, so most files open normally again. Upload your file and get a fixed copy in about 30 seconds for a typical 10-page document.
Your file is processed without an account or watermark, and deleted after one hour. You can repair up to 50 MB per upload, with 40 conversions allowed per hour per IP address. If the PDF has severe corruption beyond the index (like missing page data), the repair may not recover everything, but it handles the common 'cannot open' case reliably.
Frequently asked questions
What does repairing actually do?
It rebuilds the cross-reference table and object structure using Ghostscript. This fixes files where the body is intact but the index is broken, which is the cause of most 'damaged' errors.
Will my file be modified or watermarked?
No. The repaired output is a new clean PDF with no watermark, and your original file stays untouched on your device.
How large can my PDF be?
Up to 50 MB per file. If yours is bigger, split it first with GekiPDF's split tool, then repair each part separately.
