HTM is a document format: it stores data in the HTM format. CR2 is a image format that stores data in the CR2 format. This renders each page as a raster image, making the content viewable without a document reader. Each page is rendered at the specified DPI and saved as a separate image; text in the output is no longer selectable. Converting between these two formats is common when the source application does not support CR2 natively or when the target platform only accepts CR2. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
