Description

There select the preferred quality by adjusting the slider and type in the desired size in the text marked text field (Set file size). Now refer to snap 2 again. In the right side of the window select the folder in which the pictures you want to compress are residing. Here you may select multiple images one by one. Compression does not touch the actual dimensions of the image. Instead, it reduces the file size of a JPG, BMP, SVG or other image files. This is helpful when you plan to either upload your images online or send it via e-mail. PHP provides some default functions to compress images and to resize them. Many popular Core-PHP frameworks and CMS use default function to generate thumbnail and images without losing image quality. Image Compression in PHP Here we are going to learn how to compress an image in PHP without losing its quality in just 2 easy steps. After you compress the image, the values are 0, 0, 10, 10, 20. Previously, the image had 6 values, whereas following compression, only 3 values are present in the image, which saves up 50%. This transformation cannot be reversed, but it will improve the speed in which it takes to load your image. In short, the number of pixels remains intact.

This plugin helps make your website load much faster by reducing your image sizes up to 90%, while still keeping the same lossless quality. A significantly faster loading website will improve your SEO rankings and provide a much better experience to your customers.

Features

• Free to use with no file size limit
• Lossless compression – optimize images without losing quality
• Compress single existing individual images
• One-click bulk optimize your whole existing media library
• Automatically optimize new images on upload
• Also optimizes all thumbnail sizes
• One API key can be used on multiple sites
• Fast compression servers located in Europe & USA
• Compatible with WPML and WooCommerce
• Total savings counter (statistics page)

How does it work?

When you begin the optimization process, your images and their thumbnails are automatically sent to CompressWP’s compression servers. Your images are then analyzed and compressed in the servers, while still keeping the same lossless quality. When the images have been successfully compressed, they will be sent back to your website and replaced with the original image, which in result will use less disk space, load much faster and your visitors won’t see a difference.

How to get started?

Download and install the plugin. If necessary, follow the installation guide to set up your licence and configure the plugin.

You can either optimize individual images by clicking the “Optimize” button next to the image (it will automatically optimize the main image including the thumbnails). However, if you wish to automatically optimize all your images at once, you can click on the big green button “Bulk optimize all images” and start the process there.

Learning Outcomes

• To learn how to compress a single image.
• To learn how to compress all images within a specific directory.

A/B testing or image compression are both effective ways to streamline the experience for your website visitors. As approximately 65% of today’s online content is made of images, optimising your images is a vital tactic!

This article will show you how to effectively compress your images using Python!

Why Should You Optimise Your Images?

There are three major reasons for optimising your images:

• SEO: Smaller images means that your website or app will load faster, this ensures that users are able to consume either your content or service quickly. Also Google have stated that site speed is a small ranking factor for Google search.
• Storage: Optimised images are cheaper to store, therefore reducing your operational costs.
• Bandwidth: Optimised images require less i/o (input / output) bandwidth, which means you can get more out of your existing hosting plans, or AWS/Google Cloud Platform/Digital Ocean plans.

Image Optimisation In Python

There many libraries that allow you to easily optimise images with Python:

• Pillow – This library builds on top of PIL and can be used for the following image formats: PNG, PPM, JPEG, GIF, BMP and TIFF.
• img4web – This script optimises .jpg and .png images for the web, after running it you’ll receive lossless compression for the images.
• Tinify – This package allows you to easily integrate with tinypng.com for receiving compressed images over an API.
• Scikit-image – Scikit-learn is a machine learning package, the scikit-image package allows for advanced manipulation of images, allowing you to even return the images as numpy arrays!
• Pyguetzli – A Python binding for Google’s Guetzli library, which is a JPEG encoder that yields 20-30% smaller images in comparison to libjpeg.

For this tutorial, we will use pillow to do our image compression with python, so let’s install it:

How To Open A Single Image In Python

The most important class in Pillow is called: Image

You can use dir(Image) to see what methods and attributes are available on the Image class:

• You will then need to select the specific quality of image from 0 – 100:
• A quality of 85 doesn’t make much difference for 5 – 6mb files, and shantanujoshi found that 65 for the quality argument is the lowest reasonable number.

However, I tried with the quality set at 30 and the two images still seemed similar in terms of image quality.

How To Compress Multiple Images In The Current Working Directory

We will use Python’s OS package to find and compress every image within the current working directory:

For this example, you can download three images from pexels and put them inside of your current working directory.

Make sure to include “example” in every images’ file name:

How To Compress Multiple Images In A Specific File Directory

Okay great, hopefully you can now see how easy it is to compress multiple file images using Python!

Let’s do one more example, where we will change into a specific directory, extract all of the jpg and png files.

Then we will compress every image using Pillow.

The above function will by default run in the current working directory, however if we pass an exact directory path to it as the first argument, then we will change into that directory and perform the image compression on all .png and .jpg images there!
