If you’re interested in uploading graphics to create a custom stamp, the image will need a few tweaks before it works. Here’s a step-by-step tutorial on how to create your own in Microsoft Paint!

First, we’ll go through an example of a good conversion that will make a crisp stamp impression.

Converting Your File to a Black & White Monochrome Bitmap

Start by opening Paint. To open the file you wish to convert, go to File > Open and find the image on your computer. Click Open.

Here we chose a photo of two friends to make into a custom stamp.

Next, go to File > Save As and change “Save as type” to “Monochrome Bitmap.” Hit Save.

When Paint gives you the following message, just hit OK.

As you can see, you’ve now got a monochrome graphic that will make a crisp stamp impression. Since this photo featured darker figures on a white background, the contrast was enough to not have to make any other adjustments.

Cropping Your Image

If you want to delete some of the white space, or only feature a certain part on your stamp, Paint allows you to crop your image.

Go to Select > Rectangular selection.

Click and drag on your image until you have the selection you wish to keep. Hit Crop.

Resizing Your Image

The nice thing about Microsoft Paint is that it can show you the actual size of your image. We’ve minimized the view of our image to see the whole thing, but it’s simple to change it back to full size. Click the View tab and hit 100%.

To see how your picture measures up, check the box next to Rulers.

Obviously we don’t want to make a stamp this large, so we’ll resize it. Click back to the Home tab and hit Resize.

Check the circle next to Pixels and adjust to size you want. We are going to make our image 400 pixels horizontally. The vertical will adjust accordingly.

This change has made our image 4 inches wide. Much better to upload with!

Resaving Your Image

To re-save your file as a JPEG, go to File > Save As and change “Save as type” to “JPEG.” Hit Save. Here you have a final file you can upload to RubberStamps.com to create your custom stamp.

Inverting Colors

If you want to reverse what is black and what is white, Paint also allows you to invert the colors. To do this, go to Select > Select all.

Next, right click your selection. Choose Invert color.

The original version of this monochrome image would make a better stamp, but this trick is good to remember for other designs you might want to flip.

When Your Image Doesn’t Convert Well

Now for a not-so-good example. Say we want to make a stamp of our “Give Us a Call” logo. When we save it as a monochrome bitmap, we lose major aspects of the design.

Because the color of the phone graphic and the text of our phone number and hours are so close to the colors on which they sit, they get lost during the conversion. By changing these aspects to a drastically different color, say black or dark blue, they have a better chance of showing up in black and white. Programs like Photoshop would be best for making these changes. Otherwise, choosing a different design may be your best option.
