How to increase the size of the photo in KB

We were trying to compress the image size.

Someone sent me a MB image today and asked me to adjust it to about 30 mb.

It's a bit confusing to zoom in so much.

Then I came up with a solution.

First, increase the image size without increasing the definition, while decreasing the image size will reduce the definition.

The first method is to process the image PS to make it more complex, and the Occupied volume naturally increases. However, it is difficult to grasp the volume change, and it is difficult, and most people do not like to change the source image.

The second type of recommendation is to append other things to an image file to increase the size.

Create an empty folder first, and put the 1.8mb image into it. Then, you can get another 30 mb file that is ready to be added to the file (you can search for it and make it yourself. You are not recommended to use state secrets ).

Then create a new text document in this folder, and enter "Copy Original Image File Name. jpg/B + mixed file name. Doc = generate image file name. jpg" (not including double quotation marks). Save the file and close it. (The original image file name, mixed file name, and the name of the generated image file must be changed by yourself. It is not recommended to use Chinese characters, and the extension must be correct)

Note: The new folder should contain at least three files: the original image, the sub-file, and the text document that has entered the command. (If you cannot see the extension of a file, use the tool-Folder option-view-to display the extension of a known file so that you can see the extension.

Then select the text file with the input command, change the original suffix .txt to. bat, and save it.

If this is a text document, it will be converted into a batch file. Just execute it. A new graph is generated.
