Use Adobe Photoshop to make images smaller:

1, open Photoshop software, click on "file" in the menu bar, and then select "open".

2, from your computer when selecting the image you need to modify.

3, in the toolbar find and select the "image size" tool.

4, in the pop-up dialog box, enter the size you want to change. You can change the width, height and resolution.

5. Click the "affirm" button and your image will be narrowed.

note: If you want to keep the proportion of the original image, you should change only the width
If you do not change the resolution, then the image may be deformed.

How to use ps to make the image non-deformed become bigger and smaller

In PS to make the image non-deformed become bigger and smaller, can be achieved by the following two methods:

Method one: Adjust the size after converting to a smart objectOpen PS and remove the history record: Start the PS software to ensure that the history record and other necessary panels are displayed in the operating interface. Converts the background chart layer into a smart object: find in the diagram layer board
Background graphic layer, right-click the graphic layer, and select "convert to smart object" in the pop-up menu. Background graphic layer then turns to "graphic layer 0". Use the free conversion tool to adjust the size of : press the combination key on the keyboard to enter the free conversion state. Then, while pressing the Shift + Alt key, drag the image's edge control point to adjust the image size.Shift
The key is used to restrict the length ratio and keep the image ratio unchanged; the Alt key is scaled with the image center as a benchmark. After adjusting to the appropriate size, loose the key and the image is completed non-deformed scaling. Method 2: adjust the image size by the image size command open the image size dialog box: in the top menu bar of the PS software, then select "image" → "image size", click the left mouse button on the "image size" option, pop up the "image size" dialog box.
Compare and enter size: In the "image size" dialog box, find the icon that represents the constraining width ratio (reverse needle style), click to make it active and make sure that the proportion of length remains unchanged when adjusting the image's large-hour width ratio. Then, in the "width" and "height" input boxes, enter the desired size value as required. complete the adjustment: After entering the size, click the "definit" button, the image will be scaled according to the set size and will not deform. This method compares with the first method operating steps a little more, but can equally effectively image immutability
How to cut images to make them smaller

In Photoshop, scaled images will be smaller and proportionally unchanged through the following steps:

selected layer: make sure that the layer that contains the scaled content is selected before the operation. If not selected, the subsequent conversion operation will not be applied. free conversion tool: use the shortcut Ctrl+T (Windows) or Command+T (Mac) to activate the free conversion tool
In this case, the adjustment box around the image will appear. and so on scale : while holding the Shift button, drag any angle of the adjustment box, you can scale the image in proportion. This can prevent the image from deformation. confirms the transformation : adjust to the appropriate size, press the Enter key to confirm the transformation.

to further adjust the image to suit the background (such as filling the color matching tones), you can refer to the following steps:

lock the transparent pixel : click "lock the transparent image in the graphic layer panel"
Select the color: fill the color (such as black) through the front view selector, the background color remains default or adjusted as required. fill the color: use the shortcut Alt+Delete (Windows) or Option+Delete (Mac) to fill the front view.

Note:

must be verified during the operation to ensure the status of the chart selected to avoid mistakes.
When scaling, use the Shift key to prioritize keeping proportion to prevent image deformation. Pre-fill the color, lock the transparent pixel to ensure that the effect only acts on the target area.

Cut the image in the PS to make it smaller, you can follow the following steps:

Open the image: Start the PS software, import the image that needs to be cut. Select the Cut Tool: Find the Cut Tool (Cut-Cut) in the toolbar, click or activate the shortcut.
A dragable control box will appear around the image, moving the mouse to the edge or to the control point of the corner.

drag control point: drag the control point of the edge or corner to the inside, narrow the cut range.

keep the ratio: hold the Shift key to drag the angle control point to cut in proportion to the original chart; if you need to freely adjust the width ratio, drag directly.

0

1 confirm the cut

2 :After adjusting the cutting range, click the link button in the bar to confirm the cutting.

the image will be kept in the cutting range and the rest will be deleted.

to view the result: after the cutting is completed, the image size becomes smaller and the cutting range synchronizes.

note that the cutting operation is irreversible, it is recommended to replicate the graphic layer (Ctrl+J) before cutting, retaining the original image. This method is applicable to all versions of the PS
The operating logic is consistent.
