1. First, prepare the cr2 format files you want to convert in batches and put them all in a folder. Remember the location and name of the folder, which will be used later.

2. Next, open the ps software on the computer. Ps can be done without other messy software. Click File Options in the menu bar, and then select Script Options from the drop-down menu.

3. After selecting the script option, a submenu will pop up, where you can select the image processor option.

4. Then enter the interface of the image processor. First, select the folder where the cr2 file is located, and then click the "Select Folder" option.

5. Then a folder selection window pops up. Here, select the folder where the cr2 file is stored, and then click OK.

6. Next, select the storage location of the file. By default, it is the same as the cr2 format file, and then select the format to be converted. The first one is jpg, and of course there are psd and tiff formats. You just need to tick in front of it to choose which format. Select jpg format here, and click the Run option in the upper right corner.

7. Then there is the process of transformation. The conversion speed is related to the number of files in cr2 format you convert. Wait patiently for the conversion to be completed, and you can see the converted jpg format pictures in the storage location.
