Tagged Image File Format (TIFF) stores high-depth raster images with optional lossless LZW compression and supports multiple pages in a single file. CDR file (CDR) stores data in the CDR format. This embeds the raster image inside a document container, fixing its dimensions on the page. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. The result is a standard CDR file readable by any compatible application. 1converter handles TIFF-to-CDR conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
