Recovery Toolbox for CorelDraw may be able to recover your corrupted CDR file.
Reasons for unsuccessful CDR file recovery
Possible reasons why CorelDraw Online Recovery Service was unable to recover your damaged CorelDraw file (CDR file):
Here is a list of the most common reasons why the online CDR file recovery service (CorelDraw) may not be able to handle a damaged file:
- The file is critically damaged: most of the data is missing, and there is nothing to recover.
- The CDR file header signature is incorrect, and the service does not recognize the format.
- The file is not actually a CorelDraw CDR file. It may be a renamed PDF/AI/JPG, etc.
- The file is zero bytes in size.
- The file is empty and filled with zero bytes, possibly after a copy failure.
- The file was not fully uploaded to the service: interruption during downloading/copying/uploading.
- The file is encrypted or password-protected.
- A rare version of the format that is not supported by the service parser.
- Very old version of CDR with an outdated structure.
- Incompatible container or compression inside the CDR file that the service cannot unpack.
- Internal object tables (pages/objects) are corrupted and cannot be reconstructed.
- The resource catalog (fonts, styles, symbols) is damaged, there are no references to objects.
- Broken curve geometry (Bezier) and control points are lost.
- A layer with a critical object (e.g., master page) has been deleted or severely damaged.
- The color profile descriptor is damaged. As a result, the palette and color models are destroyed.
- Incorrect references to linked images. Possibly incorrect links that point to nowhere.
- Embedded raster images are damaged (broken PNG/JPEG headers inside the CDR file).
- Recursive and cyclic references in symbols and/or styles break the recovery.
- The font table is damaged, as a result, text blocks are not readable.
- Non-Unicode fonts/encodings are used, text metadata is destroyed.
- Errors in grouping and clipping (clip/compound paths), the structure cannot be restored.
- Incompatible transparencies and blending modes that the parser does not support.
- Macros/VBA data inside the file conflict.
- The file has been partially overwritten by another document. This has caused the data to become mixed up.
- A file system or data carrier failure has left holes in the file. Data blocks are filled with zero bytes.
- A virus or antivirus program has changed the contents of the CDR file: cut out segments, added garbage.
- The file was created or saved by a plugin that uses proprietary extensions.
- A power failure during saving resulted in critical data not being recorded.
- Nested pages and multi-page documents with broken page tables.
- The metadata block (thumbnails, descriptions) is damaged, which breaks data offsets.
- Incompatible effects (mesh fill, envelope, lens, contours) are broken.
- Error in layers (locked/hidden) — key objects are marked incorrectly/lost.
- Version conflict: opened in one version, saved downgraded with errors.
- The file was previously partially restored by third-party software, resulting in incompatible data structure.
- Compression with errors (bitstream CRC does not match), unpacking is impossible.
- Encryption or obfuscation applied by corporate DLP/DRM tool.
- Unsupported non-standard palettes/spots that break document parsing.
- Objects with zero/NaN coordinates and scales break scene math.
- Conflict between locales/decimal separators in numbers within the file.
- Internal indexes point outside the file (out-of-bounds).
- The file is open/locked by another program during loading.
- An archive/container (ZIP/RAR) is loaded instead of the .cdr file itself.
- The spline topology is broken after welding nodes, and shapes cannot be assembled.
- Compatibility error with a CDR file exported from another program, such as a converter.
- Rare bug: a specific combination of objects/styles causes a known, as yet uncorrected service error.
