Why can sometimes a 1GB file be compressed into 1M? How?

You're a multiplier, isn't it?

With the development of science and technology, more and more work can be done using computers, when we use word to write documents, in order to better send files, we can compress the oversized word document. Next, I will tell you how to do it.

The details are as follows:1The first step is to open a browser and search for the pdf** tool, click to enter the official website and find the document processing option, and select the word compression function in the pop-up menu after clicking.

2.Step 2: After entering the compressed page, click the Select File button below to add the Word document to the page.

3.Step 3: After the file is added, click the Start Compression button below to compress the file, or click the Continue to Add button to add the file.

Method Step 2

1.In order to keep the document of the word file, you can use the conversion tool for compression operation.

2.In the first step, open the PDF converter.

Click the featured conversion button above and select the Word compression option in the pop-up menu.

3.Step 2: Click on the Add File option, select the file in the pop-up window and click the Open button to add the file to the converter.

4.Step 3, click the Browse button and select the appropriate save folder in the pop-up window.

The compression level can also be set.

5.Fourth, click the Start Conversion button below or Eggplant to convert the document, and wait for the conversion to be completed.

The above is the method to compress an oversized word document for everyone.

The compression ratio is uncertain and depends on the contents of the file.

The principle of compression is to combine duplicate content in various ways. The more duplicate content, the greater the compression.

What is meant by "merging" and "duplicate content" will not be discussed from the perspective of programming, but some simple examples can be understood and felt by yourself. For example:

1111111111" is compressed to "10 1's".

123123123123" is compressed to "4 123".

0123456789" compressed to "0to9".

aaaabbbbbcdd" compressed to "4a5bc3d".

If your 1GB file is all "1", it's too small to be compressed.

If the content of your 1G file is all JPEG** or RMVB movies, then it can't be compressed, because it has been compressed, and it is difficult to find the same content to merge.

When compressing, select the compression method "best", then the compression rate is the highest, but at the expense of time. If you select "Save", it will not compress it, but just merge and copy multiple files. Generally, "Standard" is selected, the general compression rate and compression time are the most optimized, and for files that are already compressed in format, such as JPEG** or RMVB, or "Storage" is selected to save time.

I remember that when I chose compression, I chose "best", which can reduce it by about 300MB, which is not very accurate. Because it's been a long time since I've compressed a file that big.

1. When compressing, select the compression method as the best.

Two: The maximum compression ratio depends on the file type, to put it simply, if you are 1G notepad pressed out, it may only be 100MB, but if you are a movie file, it is still 1G compressed

It's not 7z compressed =,=

See what the downstairs has to say.

The method of compressing a 110m file to a 20m file is very simple, please follow the steps below:

1) After opening the document, double-click the ** you want to shrink, select "Compress**" in the pop-up options, then check "All ** in the pin group document" and "Apply to web pages and screens", and finally click "OK" and "Save Document" to complete.

2) It should be noted that selecting "Suitable for Web Pages and Screens" can achieve the maximum reduction, while selecting "Print" will slightly reduce the resolution of **, depending on your needs.
