There are several ways to enlarge a picture. Here are some methods:

1. In Paint, open your image by opening up the File menu, and then clicking the “Open” command. Find and select the image you want to resize, and then click the “Open” button. On the Home tab of the Paint toolbar, click the “Resize” button. Paint gives you the option of resizing by percentage or by pixels.

2. Use Fotor’s free online image enlarger. Select the “AI Enlarger” tool in the ”Adjust” menu, and Fotor will automatically make image bigger for you in an instant. Once finished, Click “Download” to export your enlarged image in high resolution JPG, PNG or PDF file format.

3. Upload your image using the "Select Image" button on the Enlarge to Exact Size website. Enter a new "Target Size" for your image. Click the "Enlarge Image" button to download the enlarged image.

4. In Photoshop, open your original image in Camera Raw (the plug-in, not the Photoshop filter). In the filmstrip, right-click or control-click an image file and select Enhance from the menu.

5. The grid method is an inexpensive, low-tech way to reproduce and/or enlarge an image that you want to paint or draw. The grid method can be a fairly time-intensive process, depending on how large and detailed your painting will be.
