Tux Paint Stamps for Windows

What the stamps add-on does

Tux Paint Stamps is an add-on collection of ready-made images that you can plug into Tux Paint, the free and open-source drawing app designed for children. After installation, a dedicated Stamps tool appears in the Tux Paint toolbar so users can place prepared pictures onto their canvas quickly.

What's included (sample categories)

• Vehicles (cars, trucks, bikes)
• People and characters
• Plants and flowers
• Animals and wildlife
• Seasonal items (snowflakes, suns, pumpkins)
• Food and drink
• Clothing and accessories
• Household objects
• Hobbies and sports items
• Medical-related icons
• Nature scenes and elements
• Symbols and signs

Installation and disk space

• Allow at least 50 MB of free hard-drive space to install the full stamps collection.
• The stamp images are installed into the same folder as your Tux Paint program.
• Once the files are in place, the Stamps button appears inside Tux Paint and the images become available in the interface.

How stamps work

• Each stamp is an image that uses a mask (alpha/opacity) to define its visible shape so you don’t get large rectangular backgrounds when stamping.
• Tux Paint supports multiple stamp sizes; it provides controls to scale a stamp up or down while you work.
• Be aware that when Tux Paint enlarges a small image, the result can look pixelated or jagged if the original artwork lacks sufficient resolution. The program’s largest stamp size scales to roughly 95% of the screen height.

Supported file formats and practical tips

• PNG files (with an alpha channel) and SVG vector files are both supported. PNGs can be full color or grayscale; transparency determines the stamped silhouette.
• SVGs are vector-based and are scaled to fit the canvas cleanly; ensure the vector’s artboard tightly bounds the artwork to avoid excessive whitespace.
• If your PNG stamps show a solid rectangle (often white or black) around the artwork, the image lacks transparency — add or export an alpha channel.
• If SVG stamps display lots of surrounding emptiness, increase or crop the document canvas so the shapes occupy the intended area.

Editing and inspecting stamps

• Open PNG stamps in a photo editor to view the channels — look for the Alpha channel (mask) to see how transparency is defined. Photoshop (version 4 and later) and Photoshop Elements can show channels; in GIMP the mask is visible alongside the layer.
• A single stamp can be composed of more than one file (image plus extras), but the image itself is the essential component.

Adding metadata and behaviors

• Stamps can include more than the image: they may have descriptive text, sound effects, and other options.
• Those extra settings are kept in a plain text “stamp data” file that accompanies the image and tells Tux Paint about description text, sounds, and other behaviors.

Why use stamps

Stamps make Tux Paint more engaging and educational by giving kids quick access to a large library of themed graphics — from animals and vehicles to foods and flowers — which can spark creativity and make projects faster and more fun.
