How to compress the size of a picture?

There are some methods, but there are limitations. If your picture format is in format, I'm sorry that you can only use other software, such as photoshop or fireworks. If it is in other formats, it can be realized by my following method. First of all, you should understand that jpeg format is the most compressed of all image formats. In fact, the method is very simple. You just need to draw pictures with the software that comes with your computer. Click edit on the picture to be compressed, and then you will open the picture with drawing. There is a file in the upper left corner, and a picture is saved as it. In the pop-up dialog box, the picture format will be changed to jpeg, so the saved picture will become very small, and the size and quality will remain basically the same, which is very practical.

How to compress the photo size

Compression with image processing software: Indeed, many image processing software provide image compression functions, such as Photoshop and ACDSee software, and the "drawing" tools that come with the system can compress images.

1.Photoshop compresses the picture. Open the picture file with Photoshop → File → Save as → Adjust the compression ratio. 2. Compress the image size with ACDSee software: The upload size of the article image of Sina blog is less than 300k K. Now many image processing software provide the function of image compression, but in comparison, ACDSee, which is the most widely used, is faster and easier to operate. There are many versions of ACDSee. It is recommended to use ACDSEE version 4.0 or above. The following demonstration is conducted in ACDSEE version, and other versions are similar. The two methods of image compression are as follows: 1) Convert image format. First, open the image to be modified with ACDSEE, and click Tools → Convert Format to pop up the format conversion dialog box. Since you want to compress the picture, of course, you should choose the smallest JPG format, select the format in the Format box, set the output path of the converted file, carefully check Delete Replace Original Picture, so that your original picture will be deleted, and click OK to complete the conversion. 2) Reduce the resolution of the picture. When modifying the resolution of the picture, try to control the width, height and pixels of the picture between 480*360. First, open the picture to be modified with ACDSee, click Tools → Resize to open the picture resizing dialog box, and set the picture quality with the width and height within 480 and 360 in pixels, which is also the format. 3. Use the deformation function of drawing to realize the simplest modification and reduction of the picture: start → program → attachment → drawing → opening the picture → image → stretching/deformation-there is a percentage of stretching, and the picture is reduced in proportion. For example, if the picture is 200K, you can choose to reduce it by 50-60%.

On the computer, how to compress pictures?

1. Prepare the pictures to be compressed, and search for "Thunder Online Compression" with the browser.

2. After the online compression page comes in, there are three compression options in the center of the page. Select the Online Image Compression option.

3. After entering the page, you can modify some compression settings, including compression quality and compression type.

4. After modifying the compression quality and compression type options, add the pictures to be compressed, and click the "Add File/Drag File" button.

5. After adding the picture, you can start compressing the picture by clicking the "Start Compression" button.

How to compress the photos in the computer?

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

2. Right-click the file option to open the PNG image file using the sketchpad function that comes with the system. 3. Then click the button shown in the figure to set and save the file again.

Select "Save As". 4. Next, we will choose "JPEG pictures" as the saving format. Of course, according to your needs, you can also use other pictures, but I think JPEG will not cause too much loss of image quality and occupy a small space, which is undoubtedly the best way.

Finally, fill in the name and save it. We will find that the space of the picture is much smaller than before. Originally it was 9.0 1MB, but suddenly it became1.90mb.

Method 2: 1. This method is aimed at pictures that are already in JPEG format, which can further reduce their space. In other words, we usually have compression software in our computers. If not, you can install it first. You see, the picture size is1.90mb.2. Then right-click to open the file selection list and select Add to Compressed Folder.

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

Finally, let's compare the source file with the compressed file, and you will find that the effect just now is not obvious, but it is also very good. Try it quickly! (This method is not suitable for compressed pictures in JPG format, and the effect of PNG format is obvious, but it is better for us to upload photos with compressed files. ): The basic principle of compressing a file is to find the duplicate bytes in the file, create a dictionary file with the same bytes, and represent it with a code. For example, in several places in the file, the same word "China people * * and China" is represented by a code, and it is written into the dictionary file, so that the file can be reduced.

Because the information processed by computer is expressed in the form of binary numbers, compression software marks the same string in binary information with special characters to achieve the purpose of compression. To help understand file compression, please imagine a picture of blue sky and white clouds in your mind.

For thousands of blue pixels that are monotonously repeated, instead of defining a long list of "blue, blue and blue" colors one by one, it is better to tell the computer: "Store117 blue pixels from this location", which is simple and can greatly save storage space. This is a very simple example of image compression.

In fact, in the final analysis, all computer files are stored in the form of "1" and "0". Just like blue pixels, through reasonable mathematical calculation formula, the volume of files can be greatly reduced, and the effect of "lossless and dense data" can be achieved. Generally speaking, compression can be divided into lossy compression and lossless compression.

If the loss of individual data will not have much impact, it is a good idea to ignore them, which is lossy compression. Lossy compression is widely used in animation, sound and image files, and the typical examples are 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 and rar. Pressionsoftware is naturally a tool to compress data by using the principle of compression. The file generated after compression is called archive, which is only a fraction or even smaller than the original volume.

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

How to compress the picture size with Meitu Xiu Xiu?

Meitu Xiu Xiu has three ways to compress pictures:

1. Use the "Modify Size" function in the editing interface (as shown).

2. When saving, there are two formats: and, and the images in the format will be larger after being relatively compressed.

3. Select the format when saving, and then adjust the image quality, so you can clearly see the compressed size, which is more practical than the above two methods.

Explain the picture format here:

JPEG picture (abbreviation): It was born in 1992, and photos are generally in this format, which is lossy compression, 24-bit true color (224 = 170000 color), and animation and transparent color are not supported;

PNG image format: 1996, lossless compression, the most common formats are 256 index color (PNG-8) and 24-bit true color (PNG-24) (of course, PNG supports more than this color format), supports fullalpha channel (256-level adjustable translucent color), and does not support animation.

How to compress photos The photo compression method is as follows:

Operating environment: Lenovo AIO520-22 all-in-one machine, WIN7, WinRar6. 1, etc.

1. WinRar is used to demonstrate here. First, select the picture to be compressed.

2. Then right-click the right-click menu and click Add to Compressed File.

3. Select the compression format, and finally click OK.

4. Finally, wait for the compression to be completed.

Precautions:

1, adjustment of image compression degree

The image compression degree function supports freely setting the size range of the compressed image. The smaller the value, the higher the degree of compression, but it will also lose the quality of the compressed image, so it should be compressed according to the demand.

2. Image output format

Outputting image files with different formats sometimes affects the size of compressed images.

3. Batch compression function

Online compression websites generally support batch image compression function, and the compression time of batch image compression function will be about 1-2 minutes. Please be patient.

How to compress the picture if it is too big? You can use this online image compression tool to compress image files to the size you want. For example, if you set the compression value to 100kb, after a few seconds, the online image compression tool will compress the image file size to the highest 100kb. In other words, if you set an expected value of how many kb to compress, the compressed image will be how many kb, which is very convenient.

Online intelligent image compression, compressed image size, JPG|PNG large image compression.

The use steps of online picture intelligent compression:

First, click the plus sign to add a picture to be compressed. At present, it is known to support the compression of many common image formats such as jpg, png, webp and bmp. If the selected image is displayed normally and can be compressed successfully, it means that the image format is supported.

Secondly, you can modify the maximum width and height to which the picture needs to be compressed. The default is the original width and height dimension of the picture, and the aspect ratio is automatically locked to ensure that the picture will not be deformed.

3. After compressing the image, you must set the maximum occupied space of the image file, which is necessary.

Fourthly, choose the image compression algorithm. The default is intelligent hybrid compression algorithm, and in most cases, the default algorithm can be used for image compression.

5. When you set the compression size unit as "Kb", the setting value of compression size cannot be less than 1Kb, but the final file size of compressed image can be less than 1Kb.
