在图像处理的世界里，格式转换是家常便饭。WEBP以其卓越的压缩比和对网络环境的友好性，在日常分享和网页加载中越来越普及。然而，当我们需要对图片进行深度编辑，或是将其融入专业设计流程时，WEBP的局限性便显现出来。这时，一种能保留所有图层、通道信息，并被专业软件广泛支持的格式就显得尤为重要，而PSB（大型文档格式）正是为此而生。它能够承载超高分辨率的图像数据，为创意工作者提供了无限可能。将WEBP转换为PSB，不仅是格式的切换，更是为您的创意作品打开了精修与再创作的大门，让细节得以完美保留，让专业编辑成为可能。

考虑到大陆、港澳台及东南亚地区普遍的Adobe Photoshop使用习惯，将WEBP转为PSB能确保设计师在处理大尺寸或多图层素材时，拥有最佳的兼容性和编辑自由度，避免因文件过大导致的性能瓶颈。
About WEBP to PSB Conversion
Short answer: yes, you can convert WEBP to PSB online for free, and quality is well preserved with the right settings. Just upload your .webp file to CocoConvert, pick PSB as the output, and click Convert. The whole process takes seconds.
Now for the details. WebP is Google's modern image format offering both lossy and lossless compression at 25-35% smaller sizes than JPG/PNG. PSB is a widely used file format. Converting between these two formats lets you convert between formats quickly.
Your WEBP file is decoded and re-encoded as PSB. Converting WEBP to PSB maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
