Repair Corrupted Files Online
Can't open a file? It might not be password-protected — it could be corrupted. Learn about file corruption and how specialized repair tools can restore your documents, archives, and media files.
When Your File Won't Open
Not every inaccessible file is password-protected. Sometimes files become damaged during transfer, storage, or due to software crashes. If your file won't open and you're sure it isn't encrypted, it may need repair rather than password recovery. Understanding the difference can save you time and help you choose the right solution.
Common Causes of File Corruption
Files can become corrupted for many reasons. Recognizing the cause helps determine whether the file can be repaired:
File Formats That Can Be Repaired
Documents
Microsoft Office files with damaged internal XML structure, corrupted headers, or broken content streams can often be reconstructed.
Archives
Partially downloaded or damaged archive files where the compression index or file headers are corrupted. Individual files inside may still be recoverable.
PDF Files
PDF documents with corrupted cross-reference tables, damaged page trees, or broken font embeddings can be repaired to restore readability.
Video & Media
Corrupted video files from cameras, phones, or screen recordings where the container metadata or codec headers are damaged.
Images
Photos with corrupted EXIF data, broken image headers, or truncated data streams can be partially or fully restored.
How File Repair Works
Upload Your File
Upload the corrupted file to the repair service. The tool automatically detects the file format and type of damage.
Deep Analysis
Advanced algorithms scan the file's binary structure, identify damaged sections, and reconstruct corrupted data using format-specific repair techniques.
Download Repaired File
Once repair is complete, download the restored file. For documents, the text and formatting are preserved. For archives, extractable files are recovered.

Corrupted vs. Password-Protected: File Repair or Password Recovery?
Not sure if your file needs repair (FixyFile) or password recovery (LostMyPassPro)? Here's how to tell:
| Symptom | Solution |
|---|---|
| File opens but content is garbled or unreadable | File repair — the data structure is damaged |
| Application says the file format is invalid or unrecognized | File repair — the header or metadata is corrupted |
| Application asks for a password before opening | Password recovery — the file is encrypted |
| Archive extraction fails with CRC errors | File repair — the compressed data is damaged |
| Archive asks for password during extraction | Password recovery — the archive is encrypted |
| File is 0 bytes or much smaller than expected | File may be unrecoverable — data was lost during transfer |
