About TUB files
The .TUB file format is primarily utilized as a PaintShop Pro Picture Tube. These files contain a sequence of raster image frames arranged in a grid, which Corel PaintShop Pro uses as a dynamic brush or stamp tool. A secondary use for the .TUB extension is as a project file for TubeCAD software, storing vacuum tube circuit designs.
These graphic files are natively created, opened, and managed using PaintShop Pro.
The main disadvantage of the .TUB format is its heavily proprietary nature. Outside of the PaintShop Pro ecosystem, these files are completely unrecognized by standard web browsers, mobile devices, and competing graphic editors like Adobe Photoshop. Sharing them requires the recipient to own a paid software license. Furthermore, because they hold multiple uncompressed raster layers, .TUB files can quickly become bloated in size.
To extract these image assets for web use or cross-platform editing, convert .TUB to WEBP or PNG. The PNG format is highly recommended as it retains the transparent backgrounds (alpha channels) crucial for extracting brush tools. For general sharing where transparency is not needed, convert to JPG. If you are handling a TubeCAD file, export it to PDF for archiving. Drag and drop your .TUB file here to analyze and convert it - free, online, and without installing software.
