It will convert `jpg,jpeg,png` files by default, this can be customized by editing the `config.json`.. * currently supported image format: JPEG, PNG, BMP, GIF(static image for now) > e.g When you visit `https://your.website/pics/tsuki.jpg`，it will serve as `image/webp` format without changing the URL. > > ~~For Safari and Opera users, the original image will be used.~~ > We've now support Safari/Chrome/Firefox on iOS 14/iPadOS 14 ## Simple Usage Steps(with Binary) ### 1. Prepare the environment If you'd like to run binary directly on your machine, you need to install `libaom`: `libaom` is for AVIF support, you can install it by `apt install libaom-dev` on Ubuntu, `yum install libaom-devel` on CentOS. Without this library, you may encounter error like this: `libaom.so.3: cannot open shared object file: No such file or directory` If you are using Intel Mac, you can install it by `brew install aom` If you are using Apple Silicon, you need to `brew install aom && export CPATH=/opt/homebrew/opt/aom/include/;LIBRARY_PATH=/opt/homebrew/opt/aom/lib/`, more references can be found at [在M1 Mac下开发WebP Server Go | 土豆不好吃](https://dmesg.app/m1-aom.html). If you don't like to hassle around with your system, so do us, why not have a try using Docker? >> [Docker | WebP Server Documentation](https://docs.webp.sh/usage/docker/) ### 2. Download the binary Download the `webp-server-linux-amd64` from [Releases](https://github.com/webp-sh/webp_server_go/releases) page. ### 3. Dump config file ``` ./webp-server-linux-amd64 -dump-config > config.json ``` The default `config.json` may look like this. ```json { "HOST": "127.0.0.1", "PORT": "3333", "QUALITY": "80", "IMG_PATH": "/path/to/pics", "EXHAUST_PATH": "/path/to/exhaust", "ALLOWED_TYPES": ["jpg","png","jpeg","bmp"], "ENABLE_AVIF": false } ``` > AVIF support is disabled by default as converting images to AVIF is CPU consuming. #### Config Example In the following example, the image path and website URL. | Image Path | Website Path | | ------------------------------------- | ------------------------------------ | | `/var/www/img.webp.sh/path/tsuki.jpg` | `https://img.webp.sh/path/tsuki.jpg` | The `IMG_PATH` inside `config.json` should be like: | IMG_PATH | | ---------------------- | | `/var/www/img.webp.sh` | `EXHAUST_PATH` is cache folder for output `webp` images, with `EXHAUST_PATH` set to `/var/cache/webp` in the example above, your `webp` image will be saved at `/var/cache/webp/pics/tsuki.jpg.1582558990.webp`. ### 3. Run ``` ./webp-server-linux-amd64 --config=/path/to/config.json ``` ### 4. Nginx proxy_pass Let Nginx to `proxy_pass http://localhost:3333/;`, and your WebP Server is on-the-fly. ## Advanced Usage For supervisor, Docker sections or detailed Nginx configuration, please read our documentation at [https://docs.webp.sh/](https://docs.webp.sh/) ## Support us If you find this project useful, please consider supporting us [becoming a sponsor](https://github.com/sponsors/webp-sh) or using Stripe | USD(Card, Apple Pay and Google Pay) | SEK(Card, Apple Pay and Google Pay) | CNY(Card, Apple Pay, Google Pay and Alipay) | |--------------------------------------------------|--------------------------------------------------|--------------------------------------------------| | [USD](https://buy.stripe.com/cN203sdZB98RevC3cd) | [SEK](https://buy.stripe.com/bIYbMa9JletbevCaEE) | [CNY](https://buy.stripe.com/dR67vU4p13Ox73a6oq) | |  |  |  | ## License WebP Server is under the GPLv3.
