1. A method for efficiently compressing an electronic image representing a page of an existing document, the page comprising text and graphics portions integrated together in a page structure, the method comprising: analyzing said page structure; automatically separating the page of the existing document in the electronic image into a text layer, and a raster graphics layer, and a vector graphics layer, all of said layers being logical layers in a first electronic image format; compressing said text logical layer, said raster graphics logical layer and said vector graphics logical layer into a first, second and third compressed image formats respectively, wherein said first compressed image format utilizes a first image compression method optimized for text, said second compressed image format utilizes a second image compression method optimized for raster graphics, said third compressed image format utilizes a third image compression method optimized for vector graphics; selecting the compressed image format for each logical layer to provide respectively more efficient compression therefor; decompressing said compressed text logical layer, said compressed raster graphics logical layer and said compressed vector graphics logical layer in accordance with said first, second and third image compression methods respectively; and displaying, through a Web browser, the electronic image of the page by combining said decompressed text logical layer, said decompressed raster graphics logical layer and said decompressed vector graphics logical layer for display, said combining being to reproduce said analyzed page structure from said logical layers, wherein said separating at least said text, said raster graphics, and said vector graphics portions from the page further comprises converting the page to an interconvertible format, such that said layers are separated according to said interconvertible format.
