The RM file format stores data in the RM format. Converting to PNG produces a image file that uses lossless DEFLATE compression and supports a full alpha-transparency channel, preserving every pixel exactly as encoded. 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. This makes PNG the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
