How to open an SKTZ file
You can open an SKTZ file with Sony Sketch (Android, iOS). While Sony Sketch is no longer listed in Google Play or the App Store, you can still install it on Android devices by downloading it from a reputable APK mirror site (such as APKMirror).
Since SKTZ files are Zip-compressed, you can rename the .sktz file extension to .zip , and then extract its contents with a Zip utility, such as Corel WinZip or Apple Archive Utility . This structure makes it possible to manually access and analyze the components of a Sony Sketch project, even without the original app.
How to convert an SKTZ file
Sony Sketch can convert SKTZ files to other image formats, such as .JPEG , .SVG , and .PSD .
