This is a suitable parameter if you want to reduce the image size further. This number ranges from 0 to 1 and is multiplied by the width and height of the original image to come up with a lower resolution image. If new_size_ratio is set below 1.0, then resizing is necessary.First, we use the Image.open() method to load the image to the memory, we get the size of the image file using os.path.getsize() so we can later compare this size with the new generated file's size.New_filename = f"% of the original image size.")Ī giant function that does a lot of stuff, let's cover it in more detail: # make new filename appending _compressed to the original file name Img = img.resize((width, height), Image.ANTIALIAS)įilename, ext = os.path.splitext(image_name) # if width and height are set, resize with them instead Img = img.resize((int(img.size * new_size_ratio), int(img.size * new_size_ratio)), Image.ANTIALIAS) # if resizing ratio is below 1.0, then multiply width & height with this ratio to reduce image size
Print(" Size before compression:", get_size_format(image_size)) # print the size before compression/resizing
Next, let's make our core function for compressing images: def compress_img(image_name, new_size_ratio=0.9, quality=90, width=None, height=None, to_jpg=True): Open up a new Python file and import it: import osīefore we dive into compressing images, let's grab a function from this tutorial to print the file size in a friendly format: def get_size_format(b, factor=1024, suffix="B"):įor unit in :

You can also specify the quality ratio.Īlright, to get started, let's install Pillow: $ pip install Pillow You can compress the image and resize it with a scaling factor or exact width and height.

I made the code for this tutorial as flexible as possible. For instance, you can make an API around it to reduce image sizes in batches instead of using a third-party API that may cost you money.

You're free how to use the code of this tutorial.
However, in this tutorial, you will learn to reduce image file size in Python using the Pillow library. There are a lot of tools online that offer this service most of them are a great option if you want to minimize your images quickly and reliably. Please 'Accept as answer' and ‘Upvote’ if it helped so that it can help others in the community looking for help on similar topics.Image compression is the process of minimizing the size of an image without degrading the image quality. I tried this code for compressing the incoming fileĬonst is the name of blob which triggered this function. What I would like to do is reading the file any time I upload it in a container of azure blob storage, then I want to compress it and save it in a different container with a different name, then make an API call passing as input the compressed file saved in the other container This code read a file as a stream, compress the file and write another file as a stream. Output = fs.createWriteStream('claudio-def.json') Input = fs.createReadStream('claudio.json') I have the below code that works for files but I don't know how to do the same with Azure blob storage and azure function in nodejs I was thinking to use azure blob storage and the azure function trigger. I have a working example on-premise but I would like to move the solution to cloud. I have to make an API call passing a compressed file as input.
