20 MiB, 200 pages, 500 images, 150 decoded megapixels and 40 megapixels per image. Embedded raster images only: vector drawings, text and stencil masks are not exported. Encrypted PDFs unsupported.
Original mode saves stored JPEG data byte for byte when the image is a standalone RGB or grayscale JPEG without transparency, so no recompression occurs. All other images, including JPEGs with soft masks, CMYK, JPEG 2000, JBIG2, CCITT and indexed images, are decoded by PDF.js and saved as lossless PNG; colour conversion from CMYK or special colour spaces is approximate and PNG files can be larger than the stored data. Images reused on several pages are exported once with all page numbers. Images are exported at their native resolution, not at the size or rotation shown on the page; clipping and cropping are ignored. To capture a whole page instead, use PDF to Images. Documents stay in the browser.
