**Optimizt** is a CLI tool that helps you prepare images during frontend development.

It can compress PNG, JPEG, GIF and SVG lossy and lossless and create AVIF and WebP versions for raster images.

[По-русски](./README.ru.md)

## Rationale

As frontend developers we have to care about pictures: compress PNG & JPEG, remove useless parts of SVG,
create AVIF and WebP for modern browsers, etc. One day we got tired of using a bunch of apps for that,
and created one tool that does everything we want.

## Usage

Install the tool:

```sh
npm i -g @funboxteam/optimizt
```

Optimize!

```sh
optimizt path/to/picture.jpg
```

## Command line flags

- `--avif` — create AVIF versions for the passed paths instead of compressing them.
- `--webp` — create WebP versions for the passed paths instead of compressing them.
- `-f, --force` — force create AVIF and WebP even if output file size increased or file already exists.
- `-l, --lossless` — optimize losslessly instead of lossily.
- `-v, --verbose` — show additional info, e.g. skipped files.
- `-c, --config` — use this configuration, overriding default config options if present.
- `-o, --output` — write result to provided directory.
- `-V, --version` — show tool version.
- `-h, --help` — show help.

## Examples

```bash
# one image optimization
optimizt path/to/picture.jpg

# list of images optimization losslessly
optimizt --lossless path/to/picture.jpg path/to/another/picture.png

# recursive AVIF creation in the passed directory
optimizt --avif path/to/directory

# recursive WebP creation in the passed directory
optimizt --webp path/to/directory

# recursive JPEG optimization in the current directory
find . -iname \*.jpg -exec optimizt {} +
```

## Differences between Lossy and Lossless

### Lossy (by default)

Allows you to obtain the final image with a balance between a high level of compression and a minimum level
of visual distortion.

### Lossless (--lossless flag)

When creating AVIF and WebP versions, optimizations are applied that do not affect the visual quality of the images.

PNG, JPEG, and GIF optimization uses settings that maximize the visual quality of the image at the expense of
the final file size.

When processing SVG files, the settings for Lossy and Lossless modes are identical.

## Configuration

[JPEG](https://sharp.pixelplumbing.com/api-output#jpeg), [PNG](https://sharp.pixelplumbing.com/api-output#png),
[WebP](https://sharp.pixelplumbing.com/api-output#webp), and [AVIF](https://sharp.pixelplumbing.com/api-output#avif)
processing is done using [sharp](https://github.com/lovell/sharp) library, while SVG is processed using
[svgo](https://github.com/svg/svgo) utility.

For optimizing GIFs, [gifsicle](https://github.com/kohler/gifsicle) is used, and for converting to WebP,
[gif2webp](https://developers.google.com/speed/webp/docs/gif2webp) is used.

> 💡 Lossless mode uses [Guetzli](https://github.com/google/guetzli) encoder to optimize JPEG, which allows to get
> a high level of compression and still have a good visual quality. But you should keep in mind that if you optimize
> the file again, the size may decrease at the expense of degrading the visual quality of the image.

The default settings are located in [.optimiztrc.js](./.optimiztrc.js), the file contains a list of supported parameters
and their brief description.

To disable any of the parameters, you should use `false` for the value.

When running with the `--config path/to/.optimiztrc.js` flag, the settings from the specified configuration file will
be used for image processing.

When running normally, without the `--config` flag, a recursive search for the `.optimiztrc.js` file will be performed
starting from the current directory and up to the root of the file system. If the file is not found, the default
settings will be applied.

## Integrations

### External Tool in WebStorm, PhpStorm, etc

#### Add an External Tool

Open _Preferences → Tools → External Tools_ and add a new tool with these options:

- Program: path to the exec file (usually simply `optimizt`)
- Arguments: desired ones, but use `$FilePath$` to pass Optimizt the path of the selected file or directory
- Working Directory: `$ContentRoot$`
- Synchronize files after execution: ✔️

Set other options at your discretion. For example:

![](images/ws_external-tools.png)

As you see on the screenshot above, you may add several “external tools” with the different options passed.

#### How to use

Run the tool through the context menu on a file or directory:

#### Shortcuts

To add shortcuts for the added tool go to _Preferences → Keymap → External Tools_:

![](images/ws_keymap.png)

### Tasks in Visual Studio Code

#### Add Task

Run `>Tasks: Open User Tasks` from the _Command Palette_.

In an open file, add new tasks to the `tasks` array, for example:

```javascript
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "optimizt: Optimize Image",
"type": "shell",
"command": "optimizt",
"args": [
"--verbose",
{
"value": "${file}",
"quoting": "strong"
}
],
"presentation": {
"echo": false,
"showReuseMessage": false,
"clear": true
}
},
{
"label": "optimizt: Optimize Image (lossless)",
"type": "shell",
"command": "optimizt",
"args": [
"--lossless",
"--verbose",
{
"value": "${file}",
"quoting": "strong"
}
],
"presentation": {
"echo": false,
"showReuseMessage": false,
"clear": true
}
},
{
"label": "optimizt: Create WebP",
"type": "shell",
"command": "optimizt",
"args": [
"--webp",
"--verbose",
{
"value": "${file}",
"quoting": "strong"
}
],
"presentation": {
"echo": false,
"showReuseMessage": false,
"clear": true
}
},
{
"label": "optimizt: Create WebP (lossless)",
"type": "shell",
"command": "optimizt",
"args": [
"--webp",
"--lossless",
"--verbose",
{
"value": "${file}",
"quoting": "strong"
}
],
"presentation": {
"echo": false,
"showReuseMessage": false,
"clear": true
}
}
]
}
```

#### How to use

1. Open the file for processing using Optimizt, it should be in the active tab.
2. Run `>Tasks: Run Task` from the _Command Palette_.
3. Select the required task.

#### Shortcuts

You can add shortcuts for a specific task by run `>Preferences: Open Keyboard Shortcuts (JSON)` from the _Command Palette_.

An example of adding a hotkey to run the "optimizt: Optimize Image (lossless)" task:

```javascript
// Place your key bindings in this file to override the defaults
[
{
"key": "ctrl+l",
"command": "workbench.action.tasks.runTask",
"args": "optimizt: Optimize Image (lossless)"
}
]
```

### Plugin for Sublime Text 3

You’ll find the user settings directory in one of the following paths:

- macOS: `~/Library/Application Support/Sublime Text 3/Packages/User`
- Linux: `~/.config/sublime-text-3/Packages/User`
- Windows: `%APPDATA%\Sublime Text 3\Packages\User`

#### Add plugin

Inside the settings directory create a file `optimizt.py` with the following content:

```python
import os
import sublime
import sublime_plugin

optimizt = "~/.nodenv/shims/optimizt"

class OptimiztCommand(sublime_plugin.WindowCommand):
def run(self, paths=[], options=""):
if len(paths) < 1:
return

safe_paths = ["\"" + i + "\"" for i in paths]
shell_cmd = optimizt + " " + options + " " + " ".join(safe_paths)
cwd = os.path.dirname(paths[0])

self.window.run_command("exec", {
"shell_cmd": shell_cmd,
"working_dir": cwd
})
```

Specify path to executable inside `optimizt` variable, this path can be obtained by running
`command -v optimizt` (on *nix) or `where optimizt` (on Windows).

#### Integrate the plugin into the sidebar context menu

Inside the settings directory create a file `Side Bar.sublime-menu` with the following content:

```json
[
{
"caption": "Optimizt",
"children": [
{
"caption": "Optimize Images",
"command": "optimizt",
"args": {
"paths": [],
"options": "--verbose"
}
},
{
"caption": "Optimize Images (lossless)",
"command": "optimizt",
"args": {
"paths": [],
"options": "--lossless --verbose"
}
},
{
"caption": "Create WebP",
"command": "optimizt",
"args": {
"paths": [],
"options": "--webp --verbose"
}
},
{
"caption": "Create WebP (lossless)",
"command": "optimizt",
"args": {
"paths": [],
"options": "--webp --lossless --verbose"
}
}
]
}
]
```

#### How to use

Run the tool through the context menu on a file or directory:

### Workflow for GitHub Actions

Create `optimizt.yml` file in the `.github/workflows` directory of your repository.

Insert the following code into `optimizt.yml`:

```yml
name: optimizt

on:
# Triggers the workflow on push events but only for the “main” branch
# and only when there's JPEG/PNG in the commmit
push:
branches:
- main
paths:
- "**.jpe?g"
- "**.png"

# Allows you to run this workflow manually from the Actions tab
workflow_dispatch:

jobs:
convert:
runs-on: ubuntu-latest

steps:
# Install Node.js to avoid EACCESS errors upon install packages
- uses: actions/setup-node@v2
with:
node-version: 14

- name: Install Optimizt
run: npm install --global @funboxteam/optimizt

- uses: actions/checkout@v2
with:
persist-credentials: false # otherwise, the token used is the GITHUB_TOKEN, instead of your personal token
fetch-depth: 0 # get all commits (only the last one fetched by default)

- name: Run Optimizt
run: optimizt --verbose --force --avif --webp .

- name: Commit changes
run: |
git add -A
git config --local user.email "[email protected]"
git config --local user.name "github-actions[bot]"
git diff --quiet && git diff --staged --quiet \
|| git commit -am "Create WebP & AVIF versions"

- name: Push changes
uses: ad-m/github-push-action@master
with:
github_token: ${{ secrets.GITHUB_TOKEN }}
branch: ${{ github.ref }}
```

This workflow will find all JPEG and PNG files in pushed commits and add the AVIF and WebP versions via a new commit.

More examples you can find in the [workflows](./workflows) directory.

## Troubleshooting

### “spawn guetzli ENOENT”, etc

Make sure that the [ignore-scripts](https://docs.npmjs.com/cli/v6/using-npm/config#ignore-scripts) option is not active.

See [#9](https://github.com/funbox/optimizt/issues/9).

### “pkg-config: command not found”, “fatal error: 'png.h' file not found”, etc

Some operating systems may lack of required libraries and utils, so you need to install them.

Example (on macOS via [Homebrew](https://brew.sh)):

```bash
brew install pkg-config libpng
```

## Docker

### Pull by name

```bash
docker pull funbox/optimizt
```

### Pull by name and version

```bash
docker pull funbox/optimizt:5.0.1
```

### Build the image

If you want to manually build the Docker image, you need to:

1. Clone this repo and `cd` into it.
2. Run `docker build -t funbox/optimizt .`.

OR:

- Run `docker build -t funbox/optimizt https://github.com/funbox/optimizt.git`, but keep in mind that the
[.dockerignore](.dockerignore) file will be [ignored](https://github.com/docker/cli/issues/2827).

### Run the container

Inside the container WORKDIR is set to `/src`, so by default all paths will be resolved relative to it.

Usage example:

```bash
docker run -v $(pwd):/src funbox/optimizt --webp image.png
```
