Step 2. Open your Photoshop and then go to the File tab, click Script, and choose Image Processor.

Step 3. Next, import the photos that you want to compress by clicking the Select Folder under the Select the images to process.

Step 4. After that, a new folder will be automatically created in the original folder, and this is where the compressed images will be stored or saved.

Step 6. In the Quality field, enter a number between 1 and 12. Take note that the higher the number, the bigger the file size. Meanwhile, if you are compressing JPG file formats, remember to tick the Save as JPEG box.

Photoshop 確實是大量壓縮影像的絕佳工具。對於需要專業結果的人來說，它是理想的選擇。然而，該工具需要訂閱，並且存在巨大的學習曲線，可能會導致用戶無法有效地使用該工具批量壓縮照片。

如果您的電腦裝置使用的是 Windows 10 作業系統，則可以透過 Windows Paint 應用程式批次壓縮映像。這款繪圖應用程式以其繪圖和製作草圖的功能而聞名，但除此之外，它還包含出色的照片編輯功能，例如裁剪、調整大小等。

Here’s how you can batch-compress images on Windows 10:

Step 1. Right-click on the image file that you want to compress, click Open With, and select Paint.

Step 2. Go to the Home tab and select Resize and Skew.

Step 3. After that, click on the Resize and Skew button. Here, you can resize the image by changing its percentage or pixel size. Once you have achieved your desired size, click the OK button.

Step 5. After that, go back to the File tab, click on Import to Canvas, and choose From a File.
