To convert CDR files to PDF while keeping vector quality, you need to use a conversion method that preserves vector paths instead of rasterizing the design. Vector quality is essential if the PDF will be printed or edited later, so basic converters or screenshot-based methods should be avoided.

A reliable way is to use a dedicated tool like the MailConverterTools CDR Converter, which can read CDR files directly. Add the CDR file, preview the artwork, and select PDF as the output format. The tool converts the file while maintaining vector elements, layout, and color accuracy, ensuring the resulting PDF remains sharp, scalable, and suitable for professional use.
