To compress the size of an image using Photoshop, the following four methods can be used:
1. Adjust the image resolution:
- Open the image file that needs to be compressed.
- Click "Image" > "Image Size" in the menu bar.
- In the dialog box that pops up, reduce the file size by adjusting the resolution parameter.
2. Reduce the quality of the picture:
- Click "File" > "Save As".
- Choose a new save location to avoid overwriting the original image.
- In the pop-up window, use the slider to lower the quality setting of the image, such as selecting "Low" quality to significantly reduce the file size.
3. Export to the format used for the web:
- Click on "File" > "Export" > "Save for Web".
- In the new window, you can select JPEG, PNG-8, PNG-24, and other formats, and adjust the corresponding quality and color settings.
- With the "Optimize File Size" option, you can directly set the target file size, and Photoshop will automatically adjust the settings to get closer to that size.
4. Crop unnecessary parts:
- If there is unwanted content in the image, you can remove it with the cropping tool to directly reduce the size of the image.
The above four methods are all suitable for the need to compress the size of the picture with PS. However, using PS to compress images is only suitable for a single image, and a professional image compression tool is required for batch processing of a large number of images.
