WebP codec is a library to encode and decode images in WebP format. This package
contains the library that can be used in other programs to add WebP support, as
well as the command line tools 'cwebp' and 'dwebp' to compress and decompress
images respectively.

See https://developers.google.com/speed/webp for details on the image format.

The latest source tree is available at
https://chromium.googlesource.com/webm/libwebp

It is released under the same license as the WebM project. See
https://www.webmproject.org/license/software/ or the "COPYING" file for details.
An additional intellectual property rights grant can be found in the file
PATENTS.

## Building

See the [building documentation](doc/building.md).

## Encoding and Decoding Tools

The examples/ directory contains tools to encode and decode images and
animations, view information about WebP images, and more. See the
[tools documentation](doc/tools.md).

## APIs

See the [APIs documentation](doc/api.md), and API usage examples in the
`examples/` directory.

## Bugs

Please report all bugs to the [issue tracker](https://issues.webmproject.org).
For security reports, select 'Security report' from the Template dropdown.

Patches welcome! See [how to contribute](CONTRIBUTING.md).
