The RMVB file format stores data in the RMVB format. Converting to WEBP produces a image file that supports both lossy and lossless encoding with transparency and animation, typically 25-35% smaller than equivalent JPEG or PNG files. 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 WEBP 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.
