How to compress the size of photos

Photos taken by digital cameras are basically in JPG format, and the capacity is indeed relatively large. To upload them to the Internet, they must be compressed , there are many softwares for compressing JPG format pictures. Personally, I think the best and most easy-to-use one is ACD.

ACDSee, referred to as ACD, is a famous picture viewing software. I use the Chinese version 6.0. There are many downloads available online.

After installing ACD6.0, open it with ACD, click "Modify", "Convert File Format" in the menu bar above the window, and select the format you want in "Format". Click Next and follow the prompts, it's very easy.

Also. In "Format Settings", you can adjust the compression rate, which is very important. It can compress the photo size to a very small size without basically changing the photo quality.

I have tried compressing a 1M photo in JPG format using the maximum compression rate. The image quality remains unchanged, the size is only 280KB, and the format is still JPG. Isn’t it great?

It is recommended to use ACD version 4.0 or above.

Although PHOTOSHOP can also achieve this function, this software is very large and slow to start. However, it is a professional image processing software and it is not easy to use it well.

Some people may ask? Wouldn’t the drawing program under Start, Programs, and Attachments also work?

The answer is: No! Drawing can only compress BMP format into JPG. Originally, It's just a JPG, there's nothing you can do about it.

ACDSee8.0 green cracked version 5.4M (complete functions)

How to compress photos on the computer?

The specific methods are as follows: Method 1 1. If your image format is PNG format, and the image format is If the quality requirement is not high, you can use the following method to compress the image size.

2. Right-click the file option and open the PNG image file with the system's built-in drawing board function. 3. Then click on the image. Click the button shown to set up and re-save the file.

Select "Save as" 4. Next, we will select the saving format as "JPEG image". Of course, other options are also available according to your needs. , but I think JPEG will not cause too much loss in image quality and takes up very little space. It is undoubtedly the best way.

5. Finally, fill in the name and save it. You will find that the image space is much smaller than before. It was originally 9.01MB and suddenly became 1.90MB.

Method 2 1. This method is for images that are already in JPEG format. To further reduce the space it occupies, use compression software. Our computers generally have it. If you don’t have it, you can install it first. Check that the size of the picture is 1.90MB. 2. Then right-click to open the file selection list and select "Add." to the compressed folder".

3. Select the compression method and confirm. 4. Wait for the compression software to complete the compression.

5. Finally, we will combine the source file and the compressed file. By comparison, you will find that the effect is not as obvious as before, but it is still very good. Try it now! (This method is not suitable for compressed images in JPG format. The effect of PNG format is more obvious, but it can be organized using compressed files. We upload photos better. ): The basic principle of compressing files is to find repeated bytes in the file, and create a "dictionary" file of the same bytes, and use a code to represent it, for example, there are several places in the file that are the same. The word "The People's Republic of China" is represented by a code and written into the "dictionary" file, so that the purpose of reducing the file can be achieved.

Since the information processed by the computer is in the form of binary numbers. To help understand file compression, please imagine a picture of blue sky and white clouds in your mind.

< p>For thousands of monotonically repeating blue pixels, instead of defining a long string of colors "blue, blue, blue" one by one, it is better to tell the computer: "Start from this position and store 1117 blue colors." Like "dot" is concise and can greatly save storage space. This is a very simple example of image compression.

In fact, all computer files are ultimately stored in the form of "1" and "0", just like the blue dots. As long as reasonable mathematical calculation formulas are used, the volume of the file can be Greatly compressed to achieve "data lossless density" effect. Generally speaking, compression can be divided into two types: lossy and lossless compression.

If losing individual data won't cause much impact, it's a good idea to ignore them. This is lossy compression.

Lossy compression is widely used in animation, sound and image files. Typical representatives are the video disc file format mpeg, music file format and image file format.

But in more cases the compressed data must be accurate, so people have designed lossless compression formats, such as common zip, rar, etc. Compression software is naturally a tool that uses compression principles to compress data. The file generated after compression is called an archive, and its volume is only a fraction of the original or even smaller.

Of course, the compressed package is already another file format. If you want to use the data in it, you must first use compression software to restore the data. This process is called decompression. Common compression software includes winzip, winrar, etc.
