The specific steps to reduce the size of the picture file are as follows: 1. First, drag and drop a GIF file that needs to be resized into PS to open it, click the window, and then click the timeline to adjust the timeline of PS.

2. If there are too many frames in the GIF animation file, it is easy to cause the GIF file to be too large. You can delete some unnecessary frames on the timeline first. You can select a frame every other frame and click Delete. 3. After clearing some unnecessary frames, you can click the play button to preview again. If there is no problem, you can click File, and then click Save As WEB Format.

4. At this point, in the open window, click quadruple first, and then click the color after viewing it as GIF format by default. Here, you can choose some colors that basically do not affect the visual experience, such as 128 color. 5. You can also reduce the size of the GIF file by adjusting the following color loss. As shown in the figure below, when the loss is adjusted to 13, the size of the GIF file becomes 937K.

6. In addition, if the size of the GIF animation file is too large, you can also set it to the specified size here. As shown below, when the original width 1280 is changed to 1000, the size of the GIF file becomes smaller. 7. The settings are similar. The size of the GIF file was changed in this way. Then, you can click Save, and a storage window will pop up. Take the name of the GIF file and click Save.

2. How to compress pictures in 2.GIF format?

The specific steps of compressing a picture in GIF format are as follows:

The materials we need to prepare are: computer, PS.

1. First, we open PS, click "Import" in the opened file, then select "Open Video Frame to Layer" and select to open the picture to be compressed.

2. Then we click "Save As" in the open file in the pop-up window.

3. Then in the pop-up window, click the option behind "Quality" in the lower right corner to select a value lower than the original quality.

3. How to compress the size of GIF pictures?

Use JPEG imager.

Software introduction:

This software can compress BMP, copyJPG, PNG, GIF and other graphic files to make them smaller, and can set the compression ratio, size, brightness and so on. It adopts a brand-new compression algorithm: "* * * artistic filtering", which can not only improve the visual quality of the image, but also "lose weight" the output image, so that the compressed graphic file is not distorted. You can also create a gradient JPEG image similar to the gradient GIF effect. This form of JPEG image applied to web pages can speed up the reading of web pages. Its features also include batch processing of images, effective creation of thumbnails and simple graphic processing using its own filters and image editors.

4. How to reduce the dynamic picture size without affecting the size and quality of the picture?

Any compression is not conducive to image quality, which is determined by JPG algorithm.

It's just that this kind of loss is invisible to the naked eye if it is not serious, but the quality loss can be found after careful analysis after amplification. You can try to save a large picture with low quality. The picture size is small, but the quality is also seriously lost, which is similar to the feeling of inferior video on the Internet.

If you want to ensure the quality and small size of the picture, you can try to save it in PNG format, but there may be a slight color cast problem. For example.

Do it in ps. 304*39 1 pixel size picture.

When exported, the quality is medium (about 5). The size of the saved picture may be around 30K.

I'm not sure. It may also be 10K. Why? In addition, I need to compress all the pictures below 10K without affecting the picture quality. Is there any feasible method? The general operation steps are as follows: create a new picture with pixel 304*39 1 and resolution 70. After processing the picture, export it with medium quality (5). All operations are the same, pixel 304*39 1, resolution 70, medium quality (5). Finally, some graphs are 20K and some are 30K.

I tried my best to answer your question, hoping to give you a favorable comment. Thank you very much.

5. How to compress dynamic pictures

See the specific operation.

Open the GIF compression software, it is very simple. Select File menu-Open Image on the main interface. , browse the local computer to find the GIF picture that needs to be compressed and "opened".

I chose a random picture here. Hehe, I can't find a good picture at the moment. Look at this one. I'll use it. The picture itself is very small, 998 KB. So if you want to compress, the less you can't compress, the better, but you can also compress.

This paper introduces two compression methods of software. One is to change the picture size and shrink the picture to achieve the purpose of volume compression. As shown below, select Resize Image under the Edit menu.

Bring up the corresponding editing window. PS: "Canvas size."

This option can also be used to compress pictures, but it is equivalent to cutting pictures. Adjust the size of the corner window.

As shown in the figure below, make sure "Keep original proportion" is checked; The original GIF is 320*280 pixels, so you can change the "canvas size" here, for example, 200* 175 pixels, and you can do it at will; "Quality" can also be selected, and the default is good. Then click OK to save the settings and return to the main interface.

This can achieve the effect of compression. Then choose File menu-Save As-"GIF file.

Pop up the Save As window, set the saving path and file name of the newly generated GIF picture, and "Save".

Save and export the reduced compressed file to the local computer. I got a "compressed graph 1." Here, and the file size is 866 KB, hehe, it has been reduced.

There is also a way to compress the size of GIF images. In the middle area on the right side of the toolbox, there are three options: edit, optimize and preview. We choose optimization.

As shown in the figure below, then select "Photo 16" in the "Preset" drop-down list. In addition, you can set Jitter and Loss. You can see the "compressed size" on it.

Click the "Preview" option to see the playback effect of the dynamic picture. When you are satisfied, you can click "Save".

Pop up the Save As window, and set the output path and file name of the GIF file, as shown in the following figure: "Compress Figure 2" and "Save". The size of the compressed graph 2 obtained here is 79 1 KB.

It is smaller than the original picture. If the above methods can't meet the predetermined volume, you can also reduce the volume of animation by deleting animation frames.

Look at the size comparison of the compressed demonstration pictures. What if your dynamic expression exceeds the size limit and cannot be added? Don't compress with this software.

If the GIF images we usually upload are too large, users will browse and load them relatively slowly, so compressing the image size is also convenient for transmission and browsing. By the way, although reducing the picture can make it smaller, the quality of the corresponding picture will be affected to some extent.

So please compress it moderately.
