+[Squoosh] is an image compression web app that allows you to dive into the advanced options provided
+by various image compressors.

+# Privacy
+
+Google Analytics is used to record the following:
+
+* [Basic visit data](https://support.google.com/analytics/answer/6004245?ref_topic=2919631).
+* Before and after image size once an image is downloaded. These values are rounded to the nearest
+  kilobyte.
+* If install is available, when Squoosh is installed, and what method was used to install Squoosh.
+
+Image compression is handled locally; no additional data is sent to the server.
+
+# Building locally
+
+Clone the repo, and:
+
+```sh
+npm install
+npm run build
+```
+
+You can run the development server with:

+# Codecs
+
+This folder contains a self-contained sub-project for each encoder and decoder that squoosh supplies.
+
+## Build
+
+Each subproject can be built using [Docker](https://www.docker.com/) the following commands:
+
+```
+$ npm install
+$ npm run build
+```
+
+This will build two files: `<codec name>_<enc or dec>.js` and `<codec name>_<enc or dec>.wasm`. It will most likely be necessary to set [`Module["locateFile"]`](https://kripken.github.io/emscripten-site/docs/api_reference/module.html#affecting-execution) to successfully load the `.wasm` file. When the `.js` file is loaded, a global `<codec name>_<enc or dec>` is created with the same API as an [Emscripten `Module`](https://kripken.github.io/emscripten-site/docs/api_reference/module.html).
+
+Each codec will document its API in its README.

+- Source: <https://github.com/ImageOptim/libimagequant>
+- Version: v2.12.1
+
+## Dependencies

+- Docker
+
+## Example
+
+See `example.html`

+## API
+
+### `int version()`
+
+Returns the version of libimagequant as a number. va.b.c is encoded as 0x0a0b0c
+
+### `RawImage quantize(std::string buffer, int image_width, int image_height, int numColors, float dithering)`
+
+Quantizes the given images, using at most `numColors`, a value between 2 and 256. `dithering` is a value between 0 and 1 controlling the amount of dithering. `RawImage` is a class with 3 fields: `buffer`, `width`, and `height`.

+//! This is a module that provides `malloc` and `free` for `libdeflate`.
+//! These implementations are compatible with the standard signatures
+//! but use Rust allocator instead of including libc one as well.
+//!
+//! Rust allocator APIs requires passing size and alignment to the
+//! `dealloc` function. This is different from C API, which only
+//! expects a pointer in `free` and expects allocators to take care of
+//! storing any necessary information elsewhere.
+//!
+//! In order to simulate C API, we allocate a `size_and_data_ptr`
+//! of size `sizeof(usize) + size` where `size` is the requested number
+//! of bytes. Then, we store `size` at the beginning of the allocated
+//! chunk (within those `sizeof(usize)` bytes) and return
+//! `data_ptr = size_and_data_ptr + sizeof(usize)` to the calleer:
+//!
+//! [`size`][...actual data]
+//! -^------------------ `size_and_data_ptr`
+//! ---------^---------- `data_ptr`
+//!
+//! Then, in `free`, the caller gives us `data_ptr`. We can subtract
+//! `sizeof(usize)` back and get the original `size_and_data_ptr`.
+//! At this point we can read `size` back and call the Rust `dealloc`
+//! for the whole allocated chunk.
+//!
+//! I've raised an upstream issue to hopefully make this easier in
+//! future: https://github.com/ebiggers/libdeflate/issues/62

+# WebP decoder
+
+- Source: <https://github.com/webmproject/libwebp>
+- Version: v1.0.2
+
+## Example
+
+See `example.html`
+
+## API
+
+### `int version()`
+
+Returns the version of libwebp as a number. va.b.c is encoded as 0x0a0b0c
+
+### `RawImage decode(std::string buffer)`
+
+Decodes the given webp buffer into raw RGBA. `RawImage` is a class with 3 fields: `buffer`, `width`, and `height`.

+# WebP encoder
+
+- Source: <https://github.com/webmproject/libwebp>
+- Version: v1.0.2
+
+## Dependencies
+
+- Docker
+
+## Example
+
+See `example.html`
+
+## API
+
+### `int version()`
+
+Returns the version of libwebp as a number. va.b.c is encoded as 0x0a0b0c
+
+### `UInt8Array encode(uint8_t* image_buffer, int image_width, int image_height, WebPConfig config)`
+
+Encodes the given image with given dimension to WebP.
