Repair PDF - 100% Free Online Tool
Have a PDF that will not open, displays errors, or shows corrupted content? Our Repair PDF tool attempts to reconstruct damaged or malformed PDF files by rebuilding the document structure, recovering embedded objects, and fixing cross-reference table errors — the most common causes of PDF corruption. It works on files damaged by incomplete downloads, failed saves, storage errors, or software crashes.
Upload your damaged file and the tool will process it through a repair pipeline that salvages as much content as possible. Successfully repaired PDFs can be opened in any PDF reader. While not every corruption can be fully recovered — severely fragmented files may have permanent data loss — the tool recovers content in the majority of common corruption scenarios, saving you from having to request the original file again.
Key features: Rebuilds damaged PDF structure • Fixes cross-reference errors • Recovers embedded images and text • Works on PDFs up to 100MB • No registration required • Files deleted within 1 hour

Frequently Asked Questions About Repair PDF
Everything you need to know about our Repair PDF tool
Yes, completely free. Our Repair PDF tool has no hidden costs, no watermarks, and no registration requirement. You can process as many files as you need, each up to 100MB, at no charge. We believe professional PDF tools should be accessible to everyone — students, freelancers, and businesses alike.
Your files are fully protected. All uploads and downloads use 256-bit SSL/TLS encryption during transfer. Processing happens on our isolated Hetzner server infrastructure in Germany — your file is never shared, analysed for commercial purposes, or stored longer than necessary. Every uploaded and processed file is automatically and permanently deleted within one hour of processing.
Supported file types: This tool accepts PDF files up to 100MB each. For files larger than 100MB, use our Compress PDF tool first.
Portable Document Format
Yes — works on any device. The interface is fully responsive and tested on desktop, tablet, and mobile. Touch-friendly upload areas, drag-and-drop support on desktop, and mobile-optimised buttons mean you get the same experience whether you are on a MacBook, an iPad, or an Android phone. No app download is ever required — open your browser and go.
The tool addresses the most common corruption types: damaged cross-reference tables (making pages inaccessible), broken object streams (causing blank pages or rendering errors), missing EOF markers, and structural malformation from incomplete file saves or downloads. It cannot recover content from files where the data itself is physically overwritten or encrypted without the key. Severely fragmented files may only be partially recoverable.
