PS batch processing: Convert formats and compress images

From: http://blog.sina.com.cn/s/blog_5ffdb44d0100ea57.html

When I uploaded cartoons, I found that many of the cartoons I received were in the ultra-large BMP format. Dozens of small cartoons could occupy 100 MB, which is a waste of hard disk space! Uploading is also slow, so you can use PS to compress images without affecting the image quality. The simplest way is to convert them to JPG format ~~ However, if there are so many pages, a piece of storage will probably be dead ......

In this case, the PS action and batch processing functions must be used ~~ You can process images in batches.
Even a cartoon of MB is only MB after processing! (Quality 12. If you select a smaller number in step 5, the image quality will be reduced. However, if you press too much, the image quality will be affected. Generally 10 ~ 12. I still don't know the difference. It's very important to make the noise below 8 .) You can save hundreds of MB for people who are full of hard drives and a bunch of comics ~ Although the general cartoon is JPG, there are occasional special cases.
Occasionally, the English version of ps7.0 is used for Chinese patching (and the full Chinese version may be somewhat different)


------------------------------ Preparations
1. Take a cartoon and copy the folder to prevent it (backup is a good habit ~)
2. Open the copied folder and select a BMP image in PS.
3. Open "Action panel" (if not, open "window"> "action" in the top menu bar)

------------------------------ Create an action
4. click the "Create action" button on the "Action panel" (there are 2nd actions on the right, which are the same as the "new layer"). In the displayed "new action" window, name "Save as JPG ", OK. In this way, the action is recorded. (In fact, it can be done without naming, but naming is a good habit)
5. on the menu bar, choose File> Save... "(or translated as" Save... ", do not select" save ") -- the" Save as "window is displayed: the file name does not change, and the format is" Jpeg (*. JPG; 8 *. JPEG ;*. jpe) ", make sure the Save path is the copied folder meter is incorrect, save. The "Jpeg option" is displayed: Select 12 for quality. OK. (If you want to make the image smaller, select 10 or 8. Generally, the value of is not too large, and the loss is too serious if the value is less than 8 .) Turn off the image.
6. Click the "Stop playing/recording" button on the "Action panel" to stop recording the action. In this way, the Save as JPG action is completed.

------------------------------- Batch Processing
7. In the menu bar, "file" -- "automatic" -- "batch processing..." -- the "batch processing" window is displayed.
8. select Save as JPG as the action you just created, select "folder" as the source, select the copy folder to be processed, and click OK. (Or use PS to open the image to be processed. Select Save as JPG as the action, and select Open image as the source ". In this way, you can freely select which images you want to process .)
9. The PS will automatically process the image one by one. Make a cup of tea and watch cartoons. Please wait ~ The speed depends on the number of images and the computer memory ...... Therefore, children with slow computers should not deal with too many pictures at once.

-------------------------------- Last
Turn off the PS. Delete the processed BMP image ~ Only the newly created JPG is left, And the folder is much smaller ~~

* When processing other cartoons, delete the previous action and recreate the action (Step 4 ~ 7) because the path saved in the PS action cannot be changed, you need to use the original action, and the newly saved image will go to the last folder ...... Khan. However, it is quite convenient to get used to it.
* If the format "Jpeg (*. JPG; 8 *. JPEG ;*. jpe) "option, add a step before Step 5: menu bar:" image "-" Mode "-if it is not" RGB color "but" index color, change to "RGB color.
* In Fact, I mainly want to teach PS operation recording and batch processing methods. However, when recording operations involve format changes and "Save as", PS may encounter strange errors ...... Yes. You can try it twice ...... You should not flat me tat)
* You can use this method for other images that require batch processing. You only need to change step 5 to the action you need to record. (For example, if you want to adjust the gray scale of a large pile of photos at a time, you can adjust the gray scale, contrast, color order, and color equilibrium saturation at Step 5 ...... You can also adjust the size of a batch of comics. This usage of PS will not go wrong)
(In fact, except for the children who make cartoon photos or those who often take photos of PS, the average person does not need to batch process them ...... What is a meaningless tutorial ?)
