When clients send over a logo or design in a PDF document, turning it into a production-ready embroidery file can seem like a daunting task. If you operate commercial Melco or Bernina machines, you need that artwork translated into an EXP file—the “universal commercial language” of the embroidery industry.
However, moving from a PDF document to a pure machine-code file is not a simple “Save As” operation.
In this foundational guide, we will explore exactly how to convert a PDF to an EXP embroidery file, why standard file converters don’t work, and how to create detailed PDF production worksheets from your existing EXP files.
Understanding the PDF vs. EXP Formats
To understand the conversion process, it is important to understand what each file actually contains:
PDF (Portable Document Format): A versatile document file that can contain flat raster images (like JPGs), mathematical vector paths (like SVGs), text, and formatting. It tells a screen or a printer what an image looks like.
EXP (Melco/Bernina): A highly specialized, machine-readable format. An EXP file does not contain visual pixels. Instead, it contains X and Y coordinate data, telling the embroidery machine needle exactly where to penetrate the fabric, when to jump, and when to trim the thread.
Because you are moving from visual data to mechanical instructions, converting a PDF to EXP requires a process called embroidery digitizing.

To achieve a clean, professional stitch-out, you must manually translate the artwork within the PDF into stitch data. Here is the professional workflow:
1. Extract the Artwork from the PDF
A PDF is essentially a container. Before you can digitize it, you need to extract the core image. If the PDF contains vector data, it is highly recommended to extract it as an SVG. If you are starting from other formats, you can learn more about the nuances of SVG to EXP or png to exp conversions to prepare your base art.
2. Import into Professional Digitizing Software
Once extracted, import the image into your embroidery digitizing software. Because the EXP format is a commercial standard, almost all major EXP Software (like Wilcom, Hatch, or DesignShop) supports it.
3. Digitize the Design (Assign Stitch Types)
This is where the actual “conversion” happens. A digitizer will map out the design using specific stitch types:
Satin Stitches: For text and borders.
Tatami/Fill Stitches: For large, wide areas of color.
Run Stitches: For fine details and underlay.
Underlay: Essential foundational stitches that stabilize the fabric before the top thread is laid down. (A standard image converter cannot generate underlay).
4. Export the Machine File
Once the pathing, underlay, and pull compensation are perfectly set, you can export the file. If you are unsure of the specific machine parameters needed during export, refer to our definitive guide on how to make an exp file.

Can You Use a Free PDF to EXP File Converter?
Many beginners search for a free PDF to EXP file converter or look for ways to convert PDF to EXP online free.
The short answer is: Beware of automated online converters.
Most free online tools that claim to convert a PDF to EXP free are simply renaming the file extension (e.g., changing logo.pdf to logo.exp). This completely corrupts the file. If you load a renamed file into a Melco or Bernina machine, it will either fail to read it or, worse, cause the machine needle to crash and break.
While some advanced software offers “auto-digitizing” features, these algorithms often struggle with PDFs, interpreting white backgrounds as solid blocks of stitches or misinterpreting text. For high-quality, commercial-grade results, human digitizing is always required. This rule applies across the board, whether you are converting a PDF or looking for a jpg to exp solution.
The Reverse: How to Convert EXP to PDF
Interestingly, converting EXP to PDF is a massive requirement in the commercial embroidery industry.
When you have a finished EXP embroidery file, you frequently need to generate a PDF “production worksheet” or “run sheet.” This PDF is sent to clients for design approval or handed to machine operators so they know exactly which thread colors to load into the needles.
Because EXP files do not inherently store exact color data (they only store thread stops), you need a specialized tool to render the stitches visually and generate a document.
How to create a PDF from an EXP file: You can easily generate detailed PDFs from EXP embroidery files using our EXP File Viewer. This tool allows you to visualize the machine code, verify the stitch count, and instantly download a professional PDF proof sheet for your clients or production floor.
