## Bash script to optimize your images and convert them in WebP
|
||||
|
||||
|
||||
|
||||
### Prerequisite
|
||||
|
||||
* jpegoptim
|
||||
* optipng
|
||||
* WebP
|
||||
|
||||
Debian/Ubuntu :
|
||||
|
||||
```bash
|
||||
sudo apt install jpegoptim optipng webp -y
|
||||
```
|
||||
|
||||
Centos 7 :
|
||||
|
||||
```bash
|
||||
sudo yum install optipng jpegoptim libwebp-tools -y
|
||||
```
|
||||
|
||||
### What does the script do
|
||||
|
||||
1) optimize jpg images with jpegoptim
|
||||
2) optimize png images with optipng
|
||||
3) convert jpg & png images in WebP (without deleting them)

||||

|
||||
|
||||
### Usage
|
||||
|
||||
1) Download the script and make it executable
|
||||
|
||||
```bash
|
||||
wget https://raw.githubusercontent.com/VirtuBox/wp-optimize/master/optimize.sh
|
||||
chmod +x optimize.sh
|
||||
```
|
||||
|
||||
2) Launch the script and set the path of your images as first argument
|
||||
|
||||
```bash
|
||||
./optimize.sh /path/to/your/images
|
||||
```
|
||||
|
||||
To avoid permissions issues, you can run the script with another user with sudo
|
||||
|
||||
```bash
|
||||
sudo -u www-data ./optimize.sh /path/to/your/images
|
||||
```
|
||||
|
||||
### Warning
|
||||
|
||||
Conversion process can take a while, you can use `tmux` to launch the script and be able to close your ssh connection without interrupting conversion. Then just use `tmux attach` to login back in your tmux session.
