Windows 10: how to reduce size of image on canvas

how do I reduce the size of an image on canvas

:)

 

Changing the canvas size

I know how to change the canvas size, obviously. What I mean is that when I open Paint 3D the canvas size is a weird one, I can change it, but when I open the app again it's the same weird resolution, and it's getting pretty annoying to change it every
time. It's not a huge problem, but I'd like to know how to get 1920×1080 / 2048×2048 when I open the app.

Hi Lynne,

Thank you for contacting Microsoft Community.

I would suggest you to try steps provided below and check if it helps.

Change the canvas size

The canvas size is the full editable area of an image. The Canvas Size command lets you increase or decrease an image’s canvas size. Increasing the canvas size adds space around an existing image. Decreasing an image’s canvas
size crops into the image. If you increase the canvas size of an image with a transparent background, the added canvas is transparent. If the image doesn’t have a transparent background, there are several options for determining the color of the added canvas.

1. Choose Image > Canvas Size.

2. Do one of the following:

• Enter the dimensions for the canvas in the Width and Height boxes. Choose the units of measurement you want from the pop‑up menus next to the Width and Height boxes.
• Select Relative, and enter the amount you want to add or subtract from the image’s current canvas size. Enter a positive number to add to the canvas, and enter
  a negative number to subtract from the canvas.

3. For Anchor, click a square to indicate where to position the existing image on the new canvas.

4. Choose an option from the Canvas Extension Color menu:

• Foreground to fill the new canvas with the current foreground color
• Background to fill the new canvas with the current background color
• White, Black, or Gray to fill the new canvas with that color
• Other to select a new canvas color using the Color Picker

Note:

You can also click the white square to the right of the Canvas Extension Color menu to open the Color Picker.

The Canvas Extension Color menu isn’t available if an image doesn’t contain a background layer.

5. Click OK.

How do I customize the size of Paint 3D’s Canvas?

In Paint 3D, I can click "Canvas" icon,





then can drag the canvas' corner to change the size of the canvas.









Now I wanna each time while opening Paint 3D or using it, its canvas can have a fixed custom size of matching my mind.

How should I do?

Take Paint as an example to clearly explain further:

We know, we can easily customize the size of Paint’s Canvas, as for me, I can use Notepad to create a batch file named
ResetPaintView.bat, which reads as follows:

reg add "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Applets\Paint\View" /f /v BMPWidth /t REG_DWORD /d 0x00000021

reg add "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Applets\Paint\View" /f /v BMPHeight /t REG_DWORD /d 0x00000016

(Why is its size set to so small? because I frequently paste the screenshot to Paint, so need it become small enough.)

then save it.

Each time use it, right-click on it and then run it as administrator.

This is the way that customize the size of Paint’s Canvas.

Now I wanna that Paint 3D also can customize the size of its canvas just
simply as in Paint.

Please help me.
