Turning a standard image into a machine-ready embroidery file is a frequent challenge for both hobbyists and commercial operators. Whether you are using a Melco or a high-end Bernina, understanding how to convert PNG to EXP correctly is the difference between a bird’s nest of thread and a professional-grade garment.
Understanding the PNG to EXP Gap
A PNG is a raster image file made of pixels. An EXP file, however, is a technical machine-code format. To move from one to the other, the software must assign specific stitch types, densities, and paths to those pixels.
If you are just starting out, you might wonder how to make an EXP file that actually runs smoothly. It involves more than just hitting “Save As”; it requires a process known as digitizing. For a deep dive into the technical requirements of this format, check out our How to make an EXP file for embroidery: The Definitive Guide.

Many users search for a png to exp converter online free to save time. While “auto-digitizing” tools exist, they often struggle with complex gradients or fine lines found in PNGs.
The Difference Between Auto-Conversion and Manual Digitizing:
Auto-Converters: Fast, but often produce inefficient stitch paths and high thread breakage.
Manual Digitizing: A professional plots every needle penetration to ensure the fabric doesn’t pucker.
Before you send a converted file to your machine, it is vital to inspect the stitch data. You can use our Free Online EXP File Viewer to open and analyze Melco embroidery files online before you hit start.
How to Convert PNG to EXP in Melco DesignShop (Step-by-Step)
If you are using Melco DesignShop (v10, v11, or v12), the process of turning a PNG into a production-ready EXP file is streamlined but requires attention to detail to ensure the machine reads the trims and jumps correctly.
Step 1: Import the PNG Graphic
Open Melco DesignShop and go to File > Open. Select your PNG file. Alternatively, you can use the Insert Graphic icon on the toolbar. Once the image is on the screen, ensure it is scaled to the actual size you intend to embroider.
Step 2: Image Preparation & Alignment
Before digitizing, center your graphic by pressing Ctrl + A (Select All) and then using the Center alignment tool. This ensures that when you export the EXP, the origin point $(0,0)$ is correctly aligned for your Melco hoop.
Step 3: Digitizing the Design
You have two primary paths in DesignShop:
Manual Digitizing (Recommended): Use the Column, Complex Fill, or Single Line tools to manually “punch” the design over the PNG template. This provides the highest quality for commercial EXP files.
Graphic to Stitch (Auto-Digitizing): For simple shapes, you can right-click the graphic and select Graphic to Stitch. However, be prepared to manually clean up the stitch paths to prevent excessive thread breaks.
Step 4: Define Color Changes and Trims
In the Project View (the tree on the right), ensure your color blocks are in the correct sewing order. Because EXP is a “non-object” format, it relies heavily on the software correctly inserting “Trim” and “Color Change” commands between these blocks.
Pro Tip: For a deeper look at how these commands function within the file structure, see our guide on The Ultimate Knowledge Base for the EXP File Format.
Step 5: Exporting as Melco Expanded (EXP)
Once your digitizing is complete:
Go to File > Save As.
In the “Save as type” dropdown, select Melco Expanded (*.exp).
Crucial: Ensure you do not accidentally save it as a “Bernina EXP” if you are running a Melco machine, as the jump commands may differ slightly.
By following this workflow, your PNG to EXP conversion will maintain high fidelity and run smoothly on any commercial embroidery line. If you find the manual digitizing process in DesignShop too time-consuming, you can always utilize our professional EXP Software services to handle the heavy lifting for you.
Essential Tools: EXP Software and Beyond
To change PNG to EXP file formats with precision, you need specialized software. Commercial powerhouses like Melco rely on this “universal commercial language” to execute high-precision designs.
If you’re managing a high-volume shop, understanding your EXP Software options is essential for a professional workflow. This software allows you to set “jump” commands and “trims” that a standard image converter simply cannot handle.

Why the EXP Format Matters for Commercial Success
The EXP format is unique because it is a “non-object” based file—it is pure machine code. This is why it’s often referred to as the “commercial standard.” Because it’s so streamlined, it’s highly reliable for large-scale production. To understand why this format is preferred over others like PES or DST for certain machines, explore The Ultimate Knowledge Base for the EXP File Format.
