Welcome folks today in this blog post we will be adding a text watermark to image in python using pillow library. All the full source code of the application is given below.

Get Started

In order to get started you need to install pillow library inside your python project by executing the pip command which is shown below

pip install pillow

After installing this library just create an app.py file and copy paste the following code

app.py

from PIL import Image, ImageDraw, ImageFont

#Create an Image Object from an Image
im = Image.open('###pathofimage###')
width, height = im.size

draw = ImageDraw.Draw(im)
text = "###watermark text###"

font = ImageFont.truetype('arial.ttf', 36)
textwidth, textheight = draw.textsize(text, font)

# calculate the x,y coordinates of the text
margin = 10
x = width - textwidth - margin
y = height - textheight - margin

# draw watermark in the bottom right corner
draw.text((x, y), text, font=font)
im.show()

#Save watermarked image
im.save('watermark.jpg')

Here in this block of code we are importing the library pillow and then loading the input image path so here you need to replace the path of the image and also the watermark text respectively. After this you just need to run the python application by running the below command

python app.py

As you can see the image has the watermark text attached to it at the bottom right position of the image.
