Jpeg compression software-How to compress photos

Free picture compression software 1, picture editing assistant

The interface of this tool is very simple, and its functions are comprehensive, from image cropping to batch cropping, to special functions such as watermark removal, photo restoration, smart ID photo and photo features. It is simply a picture processing artifact!

2, change the picture duck

This is an online free website. When you open the website, you can see the functions of image compression, image editing, image cropping and image format conversion. Click Image Compression to upload a picture or folder.

3, color pen

This is also an online image compression website, just select the image and upload it! This website has few functions, but it is enough for daily use.

4. Image compression software

You can batch JPEG files, resize them, and then compress and delete embedded configuration files.

SmallImage is an intelligent compression tool for PNG and JPEG. Optimize your image with a perfect balance between quality and file size. Use intelligent lossy compression technology to reduce the size of PNG file. By selectively reducing the number of colors in an image, fewer bytes are needed to store data. The effect is almost invisible, but it has a great influence on the file size!

5.OptimageforMac (lossless image compression tool)

You can adjust and convert common image and video formats and maintain the best quality required for professional photography.

Optimage is an advanced image optimization tool that can visually minimize images for websites, applications, storage and sharing. It uses advanced indicators to automatically adjust the image quality, and at most an image file as small as 10 times can be regarded as an original. By using new and traditional heuristic methods, various compression parameters and image data structures are tried to achieve the maximum compression ratio.

What compression software works well? Decompression software recommendations are as follows:

1, decompression expert. Support various formats of decompression, free version can also be encrypted and decrypted, basically all formats can be eaten, but also support the compression and decompression of volume compression packages.

2. Document management. The design style is relatively fresh, which is equivalent to the level of decompression experts. Support the decompression of all mainstream compressed packages, especially zip, RAR and 7z, support the decompression of password compressed packages, and support the compression of formats such as ZIP and 7Z, as well as the compression of encrypted volumes. ,

3. izip supports zip, rar and 7z decompression, and does not support preview after decompression.

How to compress photos How to compress the size of photos

The photos taken by digital cameras are basically in JPG format, and the capacity is really large. To upload them to the Internet, they must be compressed. There are many softwares for compressing pictures in JPG format. Personally, I think ACD is the best, the best.

ACDSee, abbreviated as ACD, is a famous software for reading pictures. I use the Chinese version of 6.0. There are many downloads online.

After installing ACD6.0, open it with ACD, click Modify and Convert File Format in the menu bar at the top of the window, select the format you want in Format, click Next, and follow the prompts. It's simple.

In addition, in the "format setting", it is very important to adjust the compression ratio, and the photo volume can be compressed very small without basically changing the image quality.

I tried. A photo in JPG format with the size of 1M, after being compressed with the maximum compression rate, has the same image quality, the size is only 280KB, and the format is still JPG. Isn't it cool?

ACD version 4.0 or above is recommended.

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

Some people may ask? Then, can't the startup, programming and drawing programs attached be enough?

The answer is: no! Drawing can only compress BMP format into JPG, which is originally JPG, so it can't be done.

ACDSee8.0 green cracked version 5.4M (full-featured)

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, and 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, there are several places in the file where the same word "People's Republic of China (PRC)" is represented by a code and 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 reduce photos with a mobile phone?

The first step is to install the software to reduce the pictures in the drawing.

Step 2, after the installation is completed, open the image restoration software. Click to select a picture, and then select the desired reduced picture.

Step 3: Click on the picture, and a menu bar will appear in the top bar. Click reduce to select the size you need, and then click the button on the right to save. The red circle on the left shows the resolution and size of the original icon. After selecting, select Save As.

Step 4, click the exclamation mark in the lower left corner of the picture, and we can now see the file size of the picture.

On the computer, how to compress pictures?
