我的图片会被上传到服务器吗？
不会。转换通过 canvas API 在浏览器中运行，图片始终留在你的设备上，也不需要账号。
免费 PNG 转 WebP 转换器
在浏览器里把 PNG 或 JPG 直接转成 WebP——无需上传、无需账号。WebP 是 Google 为网页打造的现代图片格式：它能把照片压缩成比 PNG 更小的文件，让页面加载更快。
浏览器本地处理，保护隐私
先在本地互转 WEBP、JPG、PNG，再上传、写文档或交付。

如何在浏览器中把图片转成 WebP
选择 PNG 或 JPG，在本地完成转换，下载体积更小的 WebP，用于网站或商品页面。
选择图片
从设备中选择 PNG、JPG 或 WebP 文件。文件不会被上传，只在浏览器标签页内读取。
选择目标格式
想要最小的文件就保持 WebP；如果旧版应用或电商平台不接受 WebP，可改选 JPG 或 PNG。
转换并对比大小
点击转换按钮。原图和输出文件的大小会并排显示，方便你看到文件缩小了多少。
下载结果
关闭标签页前请先保存转换后的文件，转换结果不会保存在其他任何地方。
WebP 转换器常见问题
1 2 可以设置 WebP 的质量吗？
这个工具暂不支持。有损输出（WebP 和 JPG）使用固定 90% 质量，既能保持照片清晰，又能减小文件体积；PNG 输出为无损。
3 PNG 转 WebP 会保留透明度吗？
会。带透明背景的 PNG 转成 WebP 后会保留 alpha 通道。JPG 不支持透明，转换为 JPG 时透明区域会被填充为纯色。
4 为什么有时 WebP 比 PNG 还大？
颜色单一的小图形本来就很适合用 PNG 压缩，按固定质量输出的有损 WebP 可能大小相近，甚至更大。下载前请对比页面上显示的两个文件大小。
5 可以把 WebP 转回 PNG 或 JPG 吗？
可以。把 WebP 作为源文件，目标格式选择 PNG 或 JPG，适用于不接受 WebP 的应用。
6 为什么要把 PNG 转成 WebP？
WebP 是 Google 为网页打造的现代图片格式。Google 官方数据显示，无损 WebP 比 PNG 小 26%，有损模式的压缩率更高。本工具以 90% 质量输出有损 WebP，大多数照片会比原来的 PNG 明显更小，让页面加载更快。
小提示
- 想让网页图片更小，优先导出 WEBP。
- 旧应用或平台不支持 WebP 时，可以导出 JPG 或 PNG。

- Turn One Photo into a Gaussian Splat File | TripoSplatUpload one clear photo when you want to orbit the subject. TripoSplat downloads a Gaussian splat as PLY or SPLAT, not a printable mesh. Open the generator next.
- Image to 3D Without a Local GPU | TripoSplat GuideThe generator page says you do not install a local GPU. TripoSplat turns one image into a Gaussian splat and lets you download PLY or SPLAT. Start on one image.
- A Gaussian Splat Is Not a Printable Mesh | TripoSplatA PLY or SPLAT splat is for turning a subject around in the browser. It is not an STL solid. Read this before you send the file to a printer. Not a solid part.
- Open a PLY or SPLAT File in the Browser | TripoSplatIf you already have a PLY or SPLAT file, open the free viewer. That path does not spend a generation credit. Use the generator only when you still have a photo.

- Photo to 3D File: a Splat Is Not Always a Mesh | TripoSplatThe phrase from a photo to a 3D model is ambiguous. TripoSplat publishes a Gaussian splat as PLY or SPLAT. A mesh for editing or printing is a different file.
