CGM file (CGM) stores data in the CGM format. Bitmap Image (BMP) stores uncompressed pixel data in a simple row-by-row grid, resulting in large file sizes but zero quality loss. 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. The result is a standard BMP file readable by any compatible application. 1converter handles CGM-to-BMP 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.
