How HDR to CGM Conversion Works

Converting HDR files to CGM format allows you to open, share, and use your content in applications that support CGM but not HDR. HDR and CGM differ in their internal data structure, compression method, and software ecosystem. The conversion process reads the binary or text content of the source HDR file, transforms the data into the CGM encoding scheme, and writes the result as a new file. Where possible, metadata such as creation date, author, and embedded colour profiles is preserved in the output. Quality and fidelity depend on how closely the two formats share structural features — conversions between formats in the same category (e.g., two image formats or two document formats) generally preserve content more completely than cross-category conversions. 1converter processes HDR-to-CGM conversions server-side: files are uploaded over HTTPS, converted on secure cloud infrastructure, and the output is ready to download within seconds. Converted files are automatically deleted after 24 hours.
