 [Squoosh] is an image compression web app that reduces image sizes through numerous formats.

-# API & CLI
-
-Squoosh has [an API](https://github.com/GoogleChromeLabs/squoosh/tree/dev/libsquoosh) and [a CLI](https://github.com/GoogleChromeLabs/squoosh/tree/dev/cli) to compress many images at once.
-
 # Privacy

 Squoosh does not send your image to a server. All image compression processes locally.

-# Project no longer maintained
-
-Unfortunately, due to a few people leaving the team, and staffing issues resulting from the current economic climate (ugh), this package is no longer actively maintained. I know that sucks, but there simply isn't the time & people to work on this. If anyone from the community wants to fork it, you have my blessing. The [squoosh.app](https://squoosh.app) will continue to be supported and improved.
-
-# Squoosh CLI
-
-Squoosh CLI is an _experimental_ way to run all the codecs you know from the [Squoosh] web app on your command line using WebAssembly. The Squoosh CLI uses a worker pool to parallelize processing images. This way you can apply the same codec to many images at once.
-
-Squoosh CLI is currently not the fastest image compression tool in town and doesn’t aim to be. It is, however, fast enough to compress many images sufficiently quick at once.
-
-## Installation
-
-The Squoosh CLI can be used straight from the command line without installing using `npx`:
-
-```
-$ npx @squoosh/cli <options...>
-```
-
-Of course, you can also install the Squoosh CLI:
-
-```
-$ npm i -g @squoosh/cli
-$ squoosh-cli <options...>
-```
-
-## Usage
-
-```
-Usage: squoosh-cli [options] <files...>
-
-Options:
-  -V, --version                                          output the version number
-  -d, --output-dir <dir>                                 Output directory (default: ".")
-  -s, --suffix <suffix>                                  Append suffix to output files (default: "")
-  --max-optimizer-rounds <rounds>                        Maximum number of compressions to use for auto optimizations (default: "6")
-  --optimizer-butteraugli-target <butteraugli distance>  Target Butteraugli distance for auto optimizer (default: "1.4")
-  --resize [config]                                      Resize the image before compressing
-  --quant [config]                                       Reduce the number of colors used (aka. paletting)
-  --rotate [config]                                      Rotate image
-  --mozjpeg [config]                                     Use MozJPEG to generate a .jpg file with the given configuration
-  --webp [config]                                        Use WebP to generate a .webp file with the given configuration
-  --avif [config]                                        Use AVIF to generate a .avif file with the given configuration
-  --jxl [config]                                         Use JPEG-XL to generate a .jxl file with the given configuration
-  --wp2 [config]                                         Use WebP2 to generate a .wp2 file with the given configuration
-  --oxipng [config]                                      Use OxiPNG to generate a .png file with the given configuration
-  -h, --help                                             display help for command
-```
-
-The default values for each `config` option can be found in the [`codecs.ts`][codecs.ts] file under `defaultEncoderOptions`. Every unspecified value will use the default value specified here. _Better documentation is needed here._
-
-## Auto optimizer
-
-Squoosh CLI has an _experimental_ auto optimizer that compresses an image as much as possible, trying to hit a specific [Butteraugli] target value. The higher the Butteraugli target value, the more artifacts can be introduced.
-
-You can make use of the auto optimizer by using “auto” as the config object.

-# Project no longer maintained
-
-Unfortunately, due to a few people leaving the team, and staffing issues resulting from the current economic climate (ugh), this package is no longer actively maintained. I know that sucks, but there simply isn't the time & people to work on this. If anyone from the community wants to fork it, you have my blessing. The [squoosh.app](https://squoosh.app) will continue to be supported and improved.
-
-# libSquoosh
-
-libSquoosh is an _experimental_ way to run all the codecs you know from the [Squoosh] web app directly inside your own JavaScript program. libSquoosh uses a worker pool to parallelize processing images. This way you can apply the same codec to many images at once.
-
-libSquoosh is currently not the fastest image compression tool in town and doesn’t aim to be. It is, however, fast enough to compress many images sufficiently quick at once.
-
-## Installation
-
-libSquoosh can be installed to your local project with the following command:
-
-```
-$ npm install @squoosh/lib
-```
-
-You can start using the libSquoosh by adding these lines to the top of your JS program:
-
-```js
-import { ImagePool } from '@squoosh/lib';
-import { cpus } from 'os';
-const imagePool = new ImagePool(cpus().length);
-```
-
-This will create an image pool with an underlying processing pipeline that you can use to ingest and encode images. The ImagePool constructor takes one argument that defines how many parallel operations it is allowed to run at any given time.
-
-:warning: Important! Make sure to only create 1 `ImagePool` when performing parallel image processing. If you create multiple pools, the `ImagePool` can run out of memory and crash. By reusing a single `ImagePool`, you can ensure that the backing worker queue and processing pipeline releases memory prior to processing the next image.
-
-## Ingesting images
-
-You can ingest a new image like so:
-
-```js
-import fs from 'fs/promises';
-const file = await fs.readFile('./path/to/image.png');
-const image = imagePool.ingestImage(file);
-```
-
-The `ingestImage` function can accept any [`ArrayBuffer`][arraybuffer] whether that is from `readFile()` or `fetch()`.
-
-The returned `image` object is a representation of the original image, that you can now preprocess, encode, and extract information about.
-
-## Preprocessing and encoding images
-
-When an image has been ingested, you can start preprocessing it and encoding it to other formats. This example will resize the image and then encode it to a `.jpg` and `.jxl` image:
-
-```js
-const preprocessOptions = {
-  //When both width and height are specified, the image resized to specified size.
-  resize: {
-    width: 100,
-    height: 50,
-  },
-  /*
-  //When either width or height is specified, the image resized to specified size keeping aspect ratio.
-  resize: {
-    width: 100,
-  }
-  */
-};
-await image.preprocess(preprocessOptions);
-
-const encodeOptions = {
-  mozjpeg: {}, //an empty object means 'use default settings'
-  jxl: {
-    quality: 90,
-  },
-};
-const result = await image.encode(encodeOptions);
-```
-
-The default values for each option can be found in the [`codecs.ts`][codecs.ts] file under `defaultEncoderOptions`. Every unspecified value will use the default value specified there. _Better documentation is needed here._
-
-You can run your own code inbetween the different steps, if, for example, you want to change how much the image should be resized based on its original height. (See [Extracting image information](#extracting-image-information) to learn how to get the image dimensions).
-
-## Closing the ImagePool
-
-When you have encoded everything you need, it is recommended to close the processing pipeline in the ImagePool. This will not delete the images you have already encoded, but it will prevent you from ingesting and encoding new images.
-
-Close the ImagePool pipeline with this line:
-
-```js
-await imagePool.close();
-```
-
-## Writing encoded images to the file system
-
-When you have encoded an image, you normally want to write it to a file.
-
-This example takes an image that has been encoded as a `jpg` and writes it to a file:
-
-```js
-const rawEncodedImage = image.encodedWith.mozjpeg.binary;
-
-fs.writeFile('/path/to/new/image.jpg', rawEncodedImage);
-```
-
-This example iterates through all encoded versions of the image and writes them to a specific path:
-
-```js
-const newImagePath = '/path/to/image.'; //extension is added automatically
-
-for (const encodedImage of Object.values(image.encodedWith)) {
-  fs.writeFile(newImagePath + encodedImage.extension, encodedImage.binary);
-}
-```
-
-## Extracting image information
-
-Information about a decoded image is available at `Image.decoded`. It looks something like this:
-
-```js
-console.log(await image.decoded);
-// Returns:
-{
- bitmap: {
-    data: Uint8ClampedArray(47736584) [
-      225, 228, 237, 255, 225, 228, 237, 255, 225, 228, 237, 255,
-      225, 228, 237, 255, 225, 228, 237, 255, 225, 228, 237, 255,
-      225, 228, 237, 255,
-      ... //the entire raw image
-    ],
-    width: 4606,  //pixels
-    height: 2591  //pixels
-  },
-  size: 2467795  //bytes
-}
-```
-
-Information about an encoded image can be found at `Image.encodedWith[encoderName]`. It looks something like this:
-
-```js
-console.log(image.encodedWith.jxl);
-// Returns:
-{
-  optionsUsed: {
-    quality: 75,
-    baseline: false,
-    arithmetic: false,
-    progressive: true,
-    ... //all the possible options for this encoder
-  },
-  binary: Uint8Array(1266975) [
-      1,   0,   0,   1,   0,  1,  0,  0, 255, 219,  0, 132,
-    113, 119, 156, 156, 209,  1,  8,  8,   8,   8,  9,   8,
-      9,  10,  10,   9,
-    ... //the entire raw encoded image
-  ],
-  extension: 'jxl',
-  size: 1266975  //bytes
-}
-```
-
-## Auto optimizer
-
-libSquoosh has an _experimental_ auto optimizer that compresses an image as much as possible, trying to hit a specific [Butteraugli] target value. The higher the Butteraugli target value, the more artifacts can be introduced.
-
-You can make use of the auto optimizer by using “auto” as the config object.
-
-```js
-const encodeOptions: {
-  mozjpeg: 'auto',
-}
-```

Jake Archibald	13a185def2	Remove CLI / libsquoosh (#1321 ) Unfortunately, due to a few people leaving the team, and staffing issues resulting from the current economic climate (ugh), I'm deprecating the CLI and libsquoosh parts of Squoosh. The web app will continue to be supported and improved. I know that sucks, but there simply isn't the time & people to work on this. If anyone from the community wants to fork it, you have my blessing.	2023-01-03 14:44:54 +00:00
