The conversion software is Adobe Acrobat 7.0 or above, and the PSP reading software recommends bookr.
Whether PSP can be read is unrelated to the size of the PDF file. Based on two PDF files:
1. common text is mostly the PDF of the black and white images. If it cannot be read, print it and paste the generated PDF into the memory stick. If most images are used, this method will not change the size of the PDF document. If there are many texts, the PDF size will be slightly changed, but reading will never be affected.
2. If PDF files with most color images cannot be read (generally those color pages cannot be read), try the "advanced"-> pdf Optimizer of Acrobat. You can select "average pixel sampling to"---JPEG-in the color image column. These options are saved as a compressed PDF and saved into the memory stick. If you still cannot read the image, you can continue to reduce the sample size from to, and keep the JPEG quality in progress. Because PSP cannot read large-capacity images, you can change it to a smaller value.
During optimization, if the file is generated quickly, it is not optimized in fact, and it still cannot be read from PSP. If the file generation is slow, the optimization is implemented. The optimized PDF file may be larger than the source file, but if it is optimized, the PSP can still be read even if it exceeds 100 MB. In addition, although the image accuracy is compressed, it is not obvious to get the PSP.
Summary:
If you cannot read the PDF Font, use method 1.
If the image is too large to be read, use method 2.
