Introduction
You may have noticed many images are watermarked(owner name, brand name, date, etc.) by the creator. It gives a professional look. Not only that, it also represents their intellectual properties.
You can easily add a watermark to a photo using some tools online or offline.
But did you know that the same thing can be done using a few lines of python code? Sounds great, right?
In this tutorial, we will talk about how to Add a Watermark on a Photo using Python. We're gonna use pillow module here, to perform this task.
So, Before we get started, let's take a look at what we've to install.

Requirements
Use pip3 instead of pip for Linux.
☛Install pillow: pip install pillow
Add a Text Watermark on an Image
Here we will add a text watermark to an image. Simply, follow these simple steps described below.
Steps:
1. Import Image, ImageDraw, and ImageFont modules from PIL.
2. Open the image file. In my case, "girl_image.jpg".
3. Call the Draw function from the ImageDraw module by passing the image as an argument to the function.
4. Choose a font type.
5. Select the coordinate, where you want to add the text on the image.
6. Draw the text on the photo as per the coordinate.
7. Now, save the photo with a name as per your choice.
Remove the comment(#) from the yellow marked line if you're running a Linux machine. Otherwise, keep the code as it is.
The Code
from PIL import Image, ImageDraw, ImageFont
img = Image.open('girl_image.jpg')
# Getting the height and width of the image
width, height = img.size
draw = ImageDraw.Draw(img)
text = "PySeek"
# ********For Ubuntu*********
#font = ImageFont.truetype('Ubuntu-M.ttf', 45)
# ********Default Font*******
# *****Work for everyone*****
# font = ImageFont.load_default()
# **********For Windows*********
font = ImageFont.truetype('arial.ttf', 45)
textwidth, textheight = draw.textsize(text, font)
x = width - textwidth - 10
y = height - textheight - 15
draw.text((x,y), text, font=font)
# Saving the image
img.save('watermarked.jpg')
# Open the image
img = Image.open('watermarked.jpg')
img.show()
Output
Important note for Linux User
If you run this code on a Linux system then, you may get an error message like this.
Traceback (most recent call last):
File "image_watermark.py", line 18, in <module>
font = ImageFont.truetype('arial.ttf', 45)
File "/usr/lib/python3/dist-packages/PIL/ImageFont.py", line 642, in truetype
return freetype(font)
File "/usr/lib/python3/dist-packages/PIL/ImageFont.py", line 639, in freetype
return FreeTypeFont(font, size, index, encoding, layout_engine)
File "/usr/lib/python3/dist-packages/PIL/ImageFont.py", line 187, in __init__
self.font = core.getfont(
OSError: cannot open resource
To avoid this error, use the default font or Linux Font.
To find where the Linux fonts is present, simply run this command: 'locate *.ttf' on the terminal.
I've commented two lines in the code. If your Linux distribution is Ubuntu then use that.
Ubuntu Font folder looks like this.

Add a Logo(or Image Watermark) to an Image
We added text watermark on a photo successfully. Let's try to add a logo to an image now. In this case, you need to create a perfect size logo previously. Next, you need to mention the path and size(see the yellow marked line) of it to the program before pasting.
The rest of the steps are same, as mentioned above.
In my case, I made a python logo('logo.png') before. You can try something else too.
The Code
from PIL import Image
img = Image.open('girl_image.jpg')
# Getting the height and width of the image
width, height = img.size
size = (100, 100)
logo = Image.open('logo.png')
# You can use resize method here instead of
# thumbnail method
logo.thumbnail(size)
# Location where we want to paste it on the
# main image
x = width - 100 - 10
y = height - 100 - 15
img.paste(logo, (x, y))
# Save the image
img.save('image_with_logo.jpg')
# Opening the new image
img = Image.open('image_with_logo.jpg')
img.show()
Output

Summary
In this tutorial, we learned How to Add a Watermark on an Image using a Python Program. The watermark would be in a text form or a logo. We tried both examples here.
Try to add your logo using this python program and let me know how it's working.
