About The Project

This simple image converter converts .jpg/.jpeg and .png images locally on your PC to .webp images, which can then be used on websites. It also does the following:

• It fixes the orientation of the image
• It resized the image so that the bigger dimension is 1920px if the image is bigger than that

You can also adjust the following:

• Adjust the image quality (Default is 75%)
• Crop the images to squares and decide if left/top, middle, or right/bottom is kept

Getting Started

Prerequisites

1. Download the imageConverter.php file. In the same folder, create two folders: '_old' and 'new'.
2. Add all images you want to convert to the '_old' folder.

Installation

Make sure you have PHP installed.

Usage

Navigate to your main folder in your console or terminal and run the PHP file:

  php imageConverter.php

It will ask if you want auto quality (75) or not...

  Auto quality?(y/n); y

  Auto quality?(y/n); n
  Pick the quality(0-100):

... and if you want to crop the images or not:

  Crop to square?(y/n): y
  Keep Left/Top (1), Middle (2), or Right/Bottom(3)?:

  Crop to square?(y/n): n

Here is an example of the different crop settings (Left/Top 1, Middle 2, Right/Bottom 3):

It will then browse all images in your '_old' folder and save the .webp images in the 'new' folder. It will output all scanned files for a better overview and then terminate:

  ./_old/toa-heftiba-U6uxileWeag-unsplash.jpg
