MSP to SPI: Converting Microsoft Paint Images to Photoshop Shapes

MSP and SPI are two file types with entirely different structures and purposes. MSP, short for Microsoft Paint, refers to a very old raster image format primarily associated with early versions of Microsoft Windows. On the other hand, SPI (Photoshop Shapes) is a proprietary vector format used within Adobe Photoshop to store resizable and editable shape data. Converting MSP to SPI involves more than a mere file conversion—it requires transforming a pixel-based image into a scalable, path-based vector shape. This article will guide you through the process of converting MSP files into SPI shapes, its relevance in modern design workflows, and why it can be a powerful method to repurpose legacy graphics for high-quality design applications.

Understanding MSP: Microsoft Paint Files

MSP files were introduced in the early days of Microsoft Windows as part of the Microsoft Paintbrush program. These files store raster-based image data and were typically used for creating simple bitmap illustrations. MSP supports monochrome (black and white) graphics and is considered obsolete today, with most modern systems unable to open these files directly without specialized legacy software or conversion tools. Despite being phased out, MSP files are occasionally found in archives or older digital assets, which makes it necessary to convert them into contemporary formats for reuse or enhancement.

Understanding SPI: Photoshop Shapes Format

SPI is not a widely documented format but is generally used to denote Photoshop Shape files, commonly saved with extensions like .CSH (Custom Shapes). These files are vector-based, meaning they store image information as lines and curves rather than pixels. This makes SPI files scalable to any size without quality loss—ideal for high-resolution graphics, logos, icons, and interface elements. The primary use case of Photoshop Shapes is to facilitate reusable design elements that can be edited, resized, and styled efficiently in Adobe Photoshop.

Why Convert MSP to SPI?

Converting MSP files to SPI shapes is a creative and technical process that enables graphic designers to modernize and reuse old bitmap graphics in today’s design environments. Some compelling reasons for this conversion include:

• Scalability: Raster images like MSP lose quality when scaled. Vector-based SPI shapes retain clarity at any resolution, making them suitable for print and digital media alike.
• Editability: Shapes in Photoshop can be easily edited, recolored, resized, or combined with other elements without the constraints of raster resolution.
• Legacy Asset Modernization: Designers may wish to preserve the content of old MSP files by transforming them into reusable vector shapes, allowing them to fit seamlessly into modern projects.
• Creative Flexibility: Once converted, the shapes can be manipulated using Photoshop's full suite of tools, including layer styles, masks, and blending modes.

Steps to Convert MSP to SPI

The transformation from MSP to SPI requires a few stages: converting the MSP to a readable format, tracing it to create a vector version, and importing it into Photoshop to be saved as a shape. Here’s a detailed guide:

1. Open or Convert the MSP File to a Modern Format

Since MSP is no longer supported in current systems, you need to first convert it into a readable format like PNG or BMP:

• Use legacy software like older versions of Microsoft Paint or third-party tools like IrfanView or XnView to open the MSP file.
• Save or export the file as PNG or BMP. This preserves image quality and ensures compatibility with vector design software.

2. Import the Image into a Vector Graphics Editor

Next, use Adobe Illustrator or any vector graphic software to begin the vectorization process:

• Open Illustrator and import the converted PNG/BMP file.
• Select the image and navigate to “Window” > “Image Trace.”
• Choose an appropriate tracing preset based on image complexity (e.g., “Black and White Logo” or “Detailed Illustration”).
• Adjust the threshold and path settings to fine-tune the vector output.

3. Expand and Clean Up the Vector Shapes

After tracing, you must expand the shapes to make them editable:

• Click on the traced image.
• Select “Object” > “Expand.” Ensure “Fill” and “Stroke” are selected, then click “OK.”
• Ungroup the elements if necessary and remove any undesired background or artifacts.

4. Save the Vector as SVG

Once your vector design is clean and ready, export it in SVG format to retain its path data:

• Go to “File” > “Save As.”
• Select SVG as the format and choose appropriate settings.
• Click “Save” to generate the SVG file, which can now be imported into Photoshop.

5. Import SVG into Photoshop and Convert to Shape

Open the vector SVG in Adobe Photoshop:

• Launch Photoshop and open the SVG file.
• Photoshop will import the SVG as a shape layer.
• Right-click on the layer and choose “Convert to Shape.”

You now have a vector shape in Photoshop that behaves like a native SPI shape, capable of being edited or styled using the shape tools.

6. Save as Photoshop Shape (SPI)

To save your newly converted shape for reuse:

• Select the shape layer in the Layers panel.
• Open the “Edit” menu, navigate to “Define Custom Shape.”
• Give your shape a name and click “OK.”
• Photoshop adds the shape to the Custom Shape tool, effectively storing it in SPI format.

Applications of Converted SPI Shapes

After converting your MSP image into an SPI shape, you can use it in various ways:

• Create reusable icons or UI components.
• Design scalable print material like brochures and flyers.
• Use it as a logo or decorative element in digital artwork.
• Store legacy content in a modern, editable format.

Challenges and Considerations

Despite the utility of converting MSP to SPI, there are a few technical considerations to keep in mind:

• Image Complexity: Highly detailed MSP files may not vectorize cleanly. Manual adjustments to the vector paths might be necessary.
• Loss of Color Depth: Converting to vector often focuses on outlines and shapes. Color data from the original raster may need to be reapplied manually.
• Software Compatibility: Ensure you have access to tools like Adobe Illustrator and Photoshop to handle both vector tracing and SPI creation.

Conclusion

Transforming an old Microsoft Paint (MSP) image into a modern Photoshop Shape (SPI) is a powerful way to bridge past and present design technologies. Through a series of steps involving format conversion, vectorization, and importing into Photoshop, you can preserve and repurpose legacy art assets into high-quality, scalable, and reusable design elements. This process not only enhances the longevity of digital assets but also enables greater flexibility and creativity in your design projects. Whether you’re modernizing old icons, creating scalable branding elements, or archiving graphic history, converting MSP to SPI offers a compelling pathway for creative professionals.
