Reducing the size of Adobe PDF files will improve their display, especially on the Internet *** without changing their appearance.

Sometimes you can reduce the size of an Adobe PDF file simply by using the Save As command. This action resaves the file but does not require access to the source file used to generate the Adobe PDF file.

If you receive a larger PDF document, you can use the Reduce File Size command to resample and recompress images, unembed fonts, compress document structure, and organize elements such as repeating backgrounds images and invalid bookmarks to try to reduce file size. If the file size is already small enough, this command will not work.

NOTE: Reducing the number reduces the file size of a digitally signed document without destroying the validity of the signature, which will invalidate the signature. You can also reduce file size by limiting compatibility with older versions of Adobe Acrobat.

This method is recommended if you can ensure that all users are using Acrobat 7.0.

To reduce file size: 1. Please select File > Reduce File Size.

2. Please select the compatible version you require and click OK.

Note: If you select "Acrobat 4.0 and later" and the document contains transparency, the transparency will be flattened.

PDF documents downloaded from some databases are often very large in size, such as prola, an article about EAM downloaded from APS. aps.

org/abstract/PRB/v29/i12/p6443_1 Since the file contains images instead of text content, it only has 11 pages and a size of 2. 46M.

Storage and transmission are inconvenient. Here are some ways to reduce the size.

I am using acrobat3D v8 here.

1. First open the pdf, select Document-OCR Text Recoginition-Recognize Text Using OCR in the main menu, select All pages, Primary OCR Language: English, PDF Output Style: Searchable Image, Downsample: Lowest (600dpi), and then OK Acrobat performs OCR recognition on the document content and turns it into a searchable text form. At this time, you can save it first and see that the file has changed to 1.

79MB, indicating that in addition to its own functions, OCR recognition also has the effect of reducing file size. Then Document-Reduce File Size, because 7 is generally used.

0 and above readers, so choose 7. 0 and above.

Take a look at the new file after saving. It has been reduced to 368KB. If you choose 8.

0 and above do not make the file smaller. If compressed into rar, it can be reduced to 336KB, but it is of little significance. From 2.

The reduction from 46MB to 336KB has obvious results, without any loss in display quality, and the text has also become a searchable and copyable form. The order is critical. If you Reduce File Size first and then OCR, the result will be 2.

46MB-gt; 940KB-gt; 832KB acrobat also has a function, Document-Optimize Scanned PDF, which can also reduce the size, but it has little effect on such pdf files with clean and clear text. And the display quality is degraded. The document PDFs in the literature database are basically in neat format, with clear and standardized text. They can be OCRed. I have an article by Slater in 1931, which was multi-processed from 4MB to 700KB.

It’s just that its Chinese OCR recognition effect is not good, not as good as Purple Light, although Purple Light is not that good either. As for Optimize Scanned PDF, the processed size depends on the slider to focus on quality or file size. It can also eliminate low noise and correct fonts. It is basically meaningless for documents in this type of database.

For this kind of database documents, if you zoom to the maximum size, you can probably reduce the size by about 15%, but the text effect will also be poor, so it is not worth it.

Discussion: How to reduce PDF file size? The size of some output PDF files exceeds our requirements. At this time, we need to compress it. I tried several methods: 1. Starting from Adobe Acrobat 7, the "PDF Optimizer" ("Advanced" tab ), we can use it to compress PDF files. 2. Use PDF Enhancer to compress and adjust.

3. Print your PDF file using a PDF virtual printer. Generally, the PDF size can be compressed to 30-70, depending on the composition of your PDF file. PDF virtual printer, I tried the one that comes with Adobe Acrobat Professional Edition, Bullzip PDF Printer, and PDF Factory.

I feel it is best to use Bullzip PDF Printer at this time. Sometimes using the above method, a file of about 200M can be compressed up to 70M. Please comment if it helps.

The key factor in reducing the file size is the compression rate. If you want to reduce the size of a PDF file, you must first understand this. What is the output pdf used for: is it just for screen viewing, or is it output for printing.

The prerequisite is that the pdf compression tool needs to be installed on the computer. Click the tool to open the page and click pdf compression. Click "Select File" on the PDF compression page to add files to the PDF page.

Then select the compression option. The compression ratio of the options is increasing from the left to the compression ratio. Then click the "Compress" square button on the page.
