2 from your computer when selecting the image you need to edit and upload it to Photoshop.
3, in the top menu bar, click on the "image" menu and select the "size" option.
4, in the pop-up dialog box, enter the new width and height you want. If you just want to change the size of the image without changing its resolution, then you can select the "proportional scale" option.

If you need to further optimize the quality of the image, you can select the "Save as" option in the "File" menu, and in the pop-up dialog box when choosing the appropriate format (such as JPEG or PNG) and quality level.

How to change the image size with ps
using the revision
The steps to change image size (kb) are as follows:
first, open the image
first open the ps software. click on "file" in the menu bar above, click on "open" in the drop-down menu, select the image you want to change size.second, adjust the image pixel size
click on "image" in the menu bar, click on "image size" in the drop-down menu. In the pop-up window, you can modify the pixel size (width, height or resolution), then change and click on "establish".This directly affects the image’s storage capacity, usually reducing the pixels to reduce the file size.
Third, optimize the storage format and quality
Click on the “file” in the menu bar, and click on the “format for storage as a web” in the drop-down menu. In the pop-up window, further control the file size by adjusting the following parameters:format select : JPEG format is suitable for photo class images, PNG format is suitable for transparent background or simple graphics.
quality sliderrong>: reducing the number of quality values (such as from 100% to 60%) can significantly reduce the file size, but need to balance the loss of image quality.
Image size ratio: to further narrow, you can select "adjust to width/height" and enter the target size.

confirmation parameters, click the "Save" button, select the path and name the file.0 Note:

In order to preserve the original file, it is recommended to back up the original image before the operation.
ps How to make the image smaller
in the PS, can be achieved by the following four steps:
Open the PS and import the image First start the PS software on the computer, through the "file-open" menu or directly drag, will import the images needed to process to the PS work area.
0 Copy the background layerIn order to avoid direct modification of the original chart resulting in data loss, the background layer needs to be copied. Select the background layer in the chart layer, press the shortcut keysCtrl+J (Windows system) orCommand+J (Mac system) to generate a new layer called "background copy".
Adjust image size click the "image" in the top menu bar, select the "image size" option in the dropdown menu, pop up "image size"
In the dialog box, the size can be adjusted in two ways:
Percentage adjustment : enter the percentage value directly in the "width" and "high" input boxes (such as 50% representing the reduction to the original picture 50%).
pixels/cm adjustment : Uncheck the "restricted ratio" can change the width or height separately; if you want to maintain the proportion, change the value after the selection, the other value will automatically change according to the proportion.
/strong>: If you want to reduce image clarity to reduce file size, you can reduce resolution appropriately (units: pixels/inch or pixels/cm).
Units switch: Switch units (such as pixels, centimeters, inches, etc.) to suit different requirements by pulling down the menu.
confirms and saves after adjustment is completed, click on "establish" application changes. At this time the image size has shrunk, but the file volume may not be synchronized. If you want to further compress the file size, you can use "file-export"
- Storage for the Web (Old Version)” select the JPEG format and adjust the quality parameters (such as 60-80) to balance image quality and volume.
Note:
shrinking image size can lead to loss of detail, it is recommended to choose the appropriate size according to actual use (such as web display, printing). To maintain the original ratio, be sure to select the "restricted ratio" option to avoid image deformation. When adjusting the resolution, too low values affect the quality of printing and need to be adjusted according to the output equipment. In Photos
In hop, you can reduce the image size by adjusting the image size function or by setting the quality parameter when exporting as. Specific operations are as follows:
click “image”→“image size” in the top menu bar (shortcut Alt+Ctrl+I).
in the bullet
In the outgoing window, you can modify the "width", "high" or "resolution" values. Select the "restricted ratio" to keep the width unchanged and avoid image deformation.
enter the target size (such as pixels, centimeters, etc.) or directly adjust the percentage (such as shrinking to 50%).
confirm and save: after clicking "determinate", select "file" → "stored as", save as JPEG, PNG and other formats (JPEG is suitable for photos, PNG is suitable for transparent backgrounds or simple graphics). Method 2: By "exporting as" set the qualityclick on "file" → "export" → "export as" (or "fast export to PNG").
in the pop-up window, select the format (such as JPEG), drag the "quality" slider adjust the compression level (the lower quality, the file is smaller, but may lose details).
can select "convert to sRGB" to be compatible with the web display.
save the file0 : specifySave the path and click on "Export". NOTE backup prototype: Recommended copy prototype before shrinkage, avoid coverage causes no recovery. size and quality balance: excessive shrinkage can cause blur or tear, need to be adjusted according to the purpose. For example, web graphics can adequately reduce the quality, printed images need to remain in high resolution. units select: In the "image size" window, pay attention units (pixels, inches, centimeters, etc), ensure that the requirements are met (such as the display of common pixels, printed pixels, etc.).
Print in inches or centimeters). re-sampling: If you want to significantly reduce the size, select "re-sampling" and select the algorithm (such as "two cubes" more smooth), but generate new pixels that may affect the details. Additional tools (not Photoshop)
For quick compression and not relying on Photoshop, refer to the following tools:
online tools:Compressor.io: support JPEG, P
NG and other formats, automatic size optimization.
TinyPNG: high pressure PNG, intelligent preserving transparency and low quality loss.
Pngyu: supports PNG/JPG, simple operation and suitable for bulk processing.
Desktop software0 :

2 GIMP
3 (free): adjust the size with "Image" → "Scaled Image", functionality similar to Photos
Hop.
ImageMagick(command line): Suitable for technical users, fast scale through instructions (such as convert input.jpg -resize 50% output.jpg).
Summary:The core of scaling images in Photoshop is to adjust physical size or to "export to" when compressing quality. When operating you need to pay attention to backup, unit selection and quality balance, other tools can be done.
