Reducing the size of Adobe PDF files will improve their display effect, especially when you ask about these files on the Internet, without changing their appearance.
Sometimes, you can reduce the size of Adobe PDF files by using the Save As command. This operation will save the file again, but you don't need to access the source file used to generate Adobe PDF files.
If you receive a large PDF document, you can use the "Reduce File Size" command to try to reduce the file size by resampling and recompressing the image, un-embedding fonts, compressing the document structure, and organizing repeated background images and invalid bookmarks. If the file is small enough, this command will not work.
Note: Reducing the number will reduce the file size of the digitally signed document without destroying the validity of the signature, and the digitally signed document will invalidate the signature. You can also reduce the file size by limiting compatibility with older versions of Adobe Acrobat.
If you can ensure that all users use Acrobat 7. 0, this method is recommended.
Reduce file size: 1. Please select file > reduce file size.
2。 Please select the compatible version you need, and then click OK.
Note: If you choose Acrobat 4. 0 and later ",and the document contains transparency, the transparency will be flattened.
Pdf documents in some databases are usually very large, such as downloading an article about EAM from APS. aps .
Org/abstract/prb/v29/i12/p6443 _1Because the file contains pictures instead of text, it is only 1 1 page, but the size is 2. 46 million.
It is not convenient for storage and transmission. Here's a way to reduce the size.
I use acrobat3D v8 here. 1, first open the pdf, select all pages, primary ocr language: English in the main course document -ocr text recognition-use ocr dialog box to recognize text. Pdf output style: searchable image, down sampling: minimum (600 dpi), and then confirm that acrobat performs OCR recognition on the document content, and the document content becomes a searchable text form. At this time, you can save it first and see that the file has become 1.
79MB shows that OCR recognition not only has its own function, but also reduces the file size. Then document-reduce the file size, because 7 is usually used.
There are more than 0 readers, so choose 7. 0 and above.
Look at the saved new file, which has been reduced to 368KB. If you choose 8.
0 and above will not make the file smaller. If compressed into rar, it can be compressed to 336KB, but it doesn't make much sense to start from 2.
46MB reduced to 336KB, the effect is obvious, and the display quality is not lost. By the way, text has become a searchable and reproducible form. Order is important. If you reduce the file size first and then do OCR, the result is 2.
46MB-& gt； 940 kb-& gt； 832KB acrobat also has a function, which can optimize the scanning of pdf documents and reduce the size, but it has little effect on this clean and clear PDF file, and it also reduces the display quality. The pdf of documents in the document library has neat basic format and clear text, which can be OCR. I have an article slater 193 1 year, from 4MB to 700KB.
It's just that its Chinese OCR recognition effect is not good, not as good as Ziguang, although Ziguang is not so good. As for the optimized scanned PDF, the processed size depends on the importance attached by the slider to the quality or file size, and it can also eliminate low noise and correct fonts, which is basically meaningless to the literature in this kind of database.
For this kind of database documents, the most important thing is the size, which can probably be reduced by about 15%, but the text effect is also very poor and not worth it. The pdf of documents in the document library has neat basic format and clear text, which can be OCR. I have an article slater 193 1 year, from 4MB to 700KB.
It's just that its Chinese OCR recognition effect is not good, not as good as Ziguang, although Ziguang is not so good. As for optimizing scanning.
Discussion: How to reduce the size of PDF files? Some output PDF files are larger than our requirements, so we need to compress them. I have tried several methods: 1. Starting with Adobe Acrobat 7, we provide a "PDF Optimizer" (in the "Advanced" tab), which we can use to compress PDF files. 2. Use PDF Enhancer for compression and adjustment.
3. Print a PDF file using a PDF virtual printer. Usually, you can compress the PDF size to 30%-70%, depending on the composition of your PDF file. PDF virtual printer, I tried the Bullzip PDF printer, PDF Factory, which comes with Adobe Acrobat Professional Edition.
I think it's best to use Bullzip PDF printer at this time. Sometimes with the above method, the compression of about 200M can be increased by 70M at most, which is helpful.

The key factor to reduce the file size is the compression ratio. If you want to reduce the size of the pdf file, you must first find out what the output PDF is for: just for screen browsing or for printing.

Then select the compression option. The compression ratio of the options is from left to right, and the compression ratio is getting bigger and bigger. Then click the "compress" square button on the page.
