Photoshop软件打开WebP文件格的操作教程，好吧，这是英文原版：

Photoshop 23.2+ 原生支持 WebP 格式，无需插件即可打开、编辑和保存 WebP 文件。用户可通过“文件 > 另存为副本”选择 WebP 格式，调整无损/有损压缩及质量参数。旧版 Photoshop（23.1及以下）需安装 WebPShop 插件（可从 Google 或 GitHub 下载），安装路径为共享 Creative Cloud 文件夹。macOS 用户若遇开发者验证提示，需通过终端命令解除隔离。WebP 格式优化了网页图像的压缩效率与质量平衡。

Use the WebP format in Photoshop for lossless and lossy compression of online images.

You can easily save your 8-bit RGB Photoshop documents in the WebP file format. WebP format provides both lossless and lossy compression for working with images on the web.

Update Photoshop

Native support for WebP

With Photoshop 23.2, Photoshop provides full support to the WebP file format.

Open, create, edit, and save WebP files in Photoshop without a plug-in or preference setting.

To open a WebP file, select and open it in the same way you'd open any other supported file or document. In addition to open capabilities, you can now create, edit, and save WebP files.

Follow these steps to select WebP as the preferred format for saving your file:

1. Navigate to File > Save a Copy once you've completed editing your document.

    Note

   WebP is also available as a preferred file format under File > Save As when there's no risk of file overwrite or data loss.

2. In the Save a Copy dialog box, select WebP as your preferred format from the Format drop-down and hit Save.

3. Adjust the settings as required.

   • Choose between Lossless and Lossy.
   • Use the Quality slider to decide the quality when using lossy compression. Just remember, increasing the quality also increases the file size.
   • Check options for Include XMP Metadata, Include EXIF Metadata, and Include Photoshop Extras.

   

4. Select OK after you've adjusted the settings. 

Download plug-in for Photoshop 23.1 and below

To open and save WebP images directly from Photoshop 23.1 and below, you can simply download and install the WebPShop plug-in. You can download the WebPShop plug-in (with universal/ARM support) directly from Google which owns and maintains the WebP format. Also, WebPShop is available on GitHub under an Apache 2.0 license.

• Get it from Google
• Get it from GitHub

Direct download links:

• Windows (x64): https://github.com/webmproject/WebPShop/releases/download/v0.4.3/WebPShop_0_4_3_Win_x64.8bi

Quarantine plug-in (macOS only)

Additionally, on macOS 10.15 and above, the prompt "WebPShop.plugin cannot be opened because the developer cannot be verified" can be bypassed by quarantining the plug-in. This occurs since the plug-in is not signed. The easiest way to quarantine is to drag the WebPShop plug-in into the terminal window from where it was installed to get the correct version and path.

To quarantine, run the following code in the Terminal window (Finder > Applications > Utilities):

sudo xattr -r -d com.apple.quarantine /Library/Application\ Support/Adobe/Plug-Ins/CC/WebPShop.plugin
