About CDR

CorelDRAW document

CDR stores a design document rather than only pixels. The local decoder retains supported vector paths, drawing groups, semantic text, gradients, opacity and embedded bitmap resources. Imported groups are not automatically native Corel layers.

Pages enter the shared Collection in original order. SVG retains the imported vector representation; raster targets render a page at fixed resolution. JPEG composites transparency against the chosen background. EXR and HDR transform rendered SDR colour into linear samples; they do not recover HDR.

Version and feature detection matters. Waldo, RIFF and ZIP generations differ; successful parsing is not proof of faithful rendering. Unsupported effects and text-on-path are reported. Linked files are never fetched. Saved previews are separate recovery assets, not a full document render.

History of CDR

The container evolved from old binary and RIFF records to ZIP documents with redirected data streams.

  1. CDR 7

    RIFF document generation

    The RIFF family stores document records, vector objects, styles, text and bitmap data. Version-aware parsing remains necessary.

  2. CDR X4

    ZIP document generation

    ZIP generations add packaged metadata and resource streams around the drawing data. Newer redirected streams require their own version and resource handling.

CDR compared

Different formats, different trade-offs. Choose for the image and the workflow.

SVG

CDR vs SVG

SVG exchanges supported vector shapes and live text; it does not reproduce native Corel effects.

PDF

CDR vs PDF

PDF is a page delivery format. Choose supported vector/hybrid export or rendered pages.

PNG

CDR vs PNG

PNG stores rendered page pixels with alpha; editable paths become fixed resolution.

JPEG

CDR vs JPEG

JPEG is an opaque rendered delivery image; transparency is composited against the selected background.

CDR FAQ

What does this format store?

CDR stores a design document rather than only pixels. The local decoder retains supported vector paths, drawing groups, semantic text, gradients, opacity and embedded bitmap resources. Imported groups are not automatically native Corel layers.

How does compression affect quality?

CDR remains source only. No conversion writes a CDR document.

Are original fonts and print separations preserved?

Live text needs available fonts. Outlines require supplied glyph data; substitution is labelled explicitly. Display RGB conversion does not retain CMYK or spot separations, overprint or black generation. Source ICC profiles are kept separately from converted RGB.

What should I check before opening the file?

Inspect document-specific warnings and provide missing fonts. Arbitrary Corel effects and every historical/current version are not guaranteed. Files remain in your browser.

What changes when I export to another format?

Choose vector SVG, supported vector/hybrid PDF or rendered raster/PDF. Metadata follows the shared editor and target writer. Rendering fixes resolution and colour policy; it does not recreate editable Corel objects.

When is this format useful?

Version and feature detection matters. Waldo, RIFF and ZIP generations differ; successful parsing is not proof of faithful rendering. Unsupported effects and text-on-path are reported. Linked files are never fetched. Saved previews are separate recovery assets, not a full document render.
