You have a design sitting on your computer, a simple JPG file that holds the potential for something beautiful. Maybe it is a logo for a local sports team, a monogram for a personalized gift, or a piece of artwork you created yourself. The goal is to see that design stitched into fabric, but your embroidery machine speaks a specific language. If you own a Melco machine or work with a production partner who uses them, that language is EXP. The gap between a flat image and a stitch-ready file can feel intimidating, especially if you are new to the world of embroidery digitizing. But here is the truth: with the right approach and a little patience, anyone can learn to bridge that gap. When you master the process to Convert JPG to EXP for Embroidery, you unlock the ability to create professional-quality stitch files that run smoothly and look amazing.

Understanding the EXP Format

Before we dive into the how, let us talk about the what. EXP is the native file format for Melco embroidery machines. Melco has been a major player in the commercial embroidery space for decades, and their machines are known for reliability and precision . The EXP format is compact and efficient, storing stitch data in a way that Melco machines read quickly and accurately.

Unlike some other formats that store additional metadata, EXP focuses on the essentials: stitch coordinates, color change commands, and jump stitches. This simplicity makes it reliable, but it also means the format does not hold extra information like thread brand recommendations or design notes . The digitizing process must account for that by building all necessary instructions directly into the stitch data.

If you own a Melco machine, or if you send designs to someone who does, EXP is the language you need to speak. Converting your JPG images to this format correctly ensures your designs stitch out exactly as intended.

Why JPG Is Not Enough

Here is a fundamental truth that every embroiderer learns eventually: a JPG file is just a picture. It shows your design on a screen, but it tells a machine nothing about how to create that design with thread. JPGs contain pixels, thousands of tiny colored squares arranged in a grid. Zoom in close enough, and you see the squares. Zoom out, and your eyes blend them into a continuous image.

Embroidery machines do not see pixels. They see coordinates. They need to know exactly where to plunge the needle, how long each stitch should be, and when to change colors. Creating that information from a JPG requires interpretation. You have to look at the flat image and decide which parts become satin stitches, which become fills, and how the thread should flow through curves and corners.

This process is called digitizing. It is part art, part science, and entirely necessary for turning pictures into embroidery.

Step One: Prepare Your Source Image

Every successful conversion starts with the source material. You cannot create a quality EXP file from a poor-quality JPG. The digitizing software needs clear information to work with.

Start by evaluating your JPG. Is it high resolution? For embroidery purposes, you want at least 300 DPI at the final stitch size. If your image is small and pixelated, scaling it up in photo editing software will only make it blurrier . You may need to have the design redrawn as vector art before proceeding.

Look at the contrast. Does the design have clear edges between different colors? High contrast makes digitizing easier because the software and your eyes can distinguish boundaries. Low contrast images with subtle color shifts create confusion.

Consider the complexity. Does your design have tiny text or extremely thin lines? Embroidery has physical limitations. Text smaller than about a quarter inch rarely stitches legibly . Lines thinner than two millimeters can break or disappear. If your JPG contains these elements, decide whether they are essential or if the design needs simplification.

If you have access to vector editing software like Inkscape, consider converting your JPG to vector paths first. Clean vector art gives your digitizing software the best possible starting point .

Step Two: Choose Your Digitizing Software

You cannot create EXP files with standard graphic design programs. Photoshop and Illustrator design for screens and paper, not needles and thread. To convert JPG to EXP, you need dedicated embroidery digitizing software that supports Melco's format.

Hatch Embroidery

Hatch by Wilcom is one of the most popular choices for serious embroiderers. It offers professional-grade digitizing tools in an accessible package . Hatch supports EXP format, letting you save your work directly in the language Melco machines understand.

The software includes both auto-digitize features for quick results and full manual controls for professional work. Manual digitizing gives you control over every stitch, every underlay layer, and every density setting. For consistent professional results, manual is the way to go.

Wilcom Embroidery Studio

Wilcom Embroidery Studio is the industry standard for professional digitizers. It offers complete control over every aspect of embroidery design . While it is expensive and has a steep learning curve, it supports EXP format and handles the most complex designs with ease. If you plan to digitize professionally, Wilcom Studio is worth the investment.

Ink/Stitch

For budget-conscious users, Ink/Stitch provides a free, open-source alternative. It runs as an extension to Inkscape and supports various embroidery formats including EXP . The learning curve is real, but the capability is surprising for free software.

Ink/Stitch includes manual digitizing tools, stitch simulation, and control over density and underlay. With practice, you can create professional-quality EXP files without spending a dime .

Embird

Embird takes a modular approach to embroidery software. You can start with the basic editor and add digitizing modules as your skills grow . Embird supports format conversion, including to and from EXP, making it flexible for users who work with multiple machine types.

Step Three: Import and Trace

Open your chosen software and import your JPG. Most programs allow you to place the image as a template that you trace manually. Manual tracing gives you complete control over every shape and path.

If your software includes auto-trace features, you can use them to generate initial shapes, but be prepared to clean up the results. Auto-trace often creates unnecessary anchor points or misinterprets edges . Professional digitizers trace manually because it produces cleaner, more efficient stitch paths.

As you trace, think about how each shape will stitch. Complex curves may need additional anchor points. Straight lines can remain simple. The goal is to create clean vector paths that your software can convert into smooth stitches.

Trace each color area separately. If your logo uses three colors, you should end up with three distinct shapes or groups of shapes. This separation makes assigning stitch types and colors much easier later.

Step Four: Assign Stitch Types

Different parts of your design require different stitch types. Choosing correctly makes a huge difference in the final result.

Satin stitches work beautifully for borders, letters, and narrow columns. They create a smooth, raised surface that catches light and gives designs a professional finish. But satin stitches have width limits. If a column exceeds about half an inch, the stitches become too long and may snag or look loose .

Tatami fills, also called pattern fills, handle larger areas. They use a staggered pattern that covers well without pulling the fabric excessively. The stitch direction in tatami fills affects how light reflects, so choose angles that complement the design.

Running stitches handle fine details, outlines, and small text. They are simple and quick but offer less coverage than other stitch types. Use them for delicate elements where heavier stitches would overwhelm.

Complex fills add texture and visual interest to large areas. Experiment with different patterns to see what works for your design.

Step Five: Add Underlay

Underlay is the hidden foundation that separates amateur embroidery from professional work. It consists of stitches laid down before the main design appears, and it serves several vital purposes .

Underlay stabilizes the fabric, creating a firm base that prevents shifting and puckering. It provides coverage, filling gaps and preventing the fabric from showing through the design. It defines edges, creating a clean border that the top stitches can follow precisely.

For most designs on standard fabrics, a combination of edge run underlay and zigzag underlay works well. Edge run underlay traces the outline of a shape, defining its borders. Zigzag underlay fills the interior with a loose, basting-like stitch that preps the surface for dense top stitches.

The exact underlay settings depend on your fabric. Heavy denim needs different underlay than lightweight polyester. Large fill areas need more underlay than small details.

Step Six: Adjust Density and Pull Compensation

Stitch density determines how closely stitches pack together. Too dense, and the fabric puckers. Thread breaks increase. The design feels stiff. Too loose, and the fabric shows through. The design looks cheap .

For most designs on medium-weight fabrics, a density around 0.4 to 0.5 millimeters works well. But you must adjust based on fabric. Terry cloth can handle slightly denser stitches. Performance knits need lighter density to prevent tunneling.

Pull compensation addresses fabric distortion. When stitches pull on fabric, especially knits, the material stretches. Shapes that should be circles can pull into ovals. Pull compensation widens shapes slightly in the digitizing phase, anticipating this distortion and canceling it out .

The right pull compensation varies by fabric and stitch direction. Testing on your actual fabric reveals what works.

Step Seven: Export to EXP Format

You have digitized your design, adjusted every parameter, and previewed the stitch simulation. Now it is time to create the actual EXP file your Melco machine will read.

In your software, select export or save as and choose EXP format. Some programs offer multiple export options. Choose the standard version for maximum compatibility with your specific machine .

Name your file descriptively. Include the design name, size, and any relevant notes. A file named client_logo_chest_4in.exp tells you everything months later when you need to re-run the job. Store files in an organized system for easy retrieval.

Transfer the EXP file to your Melco machine via USB, network, or direct connection depending on your model. Load it, select your threads, and prepare to test.

Step Eight: The Essential Test Stitch-Out

You have done all the work on screen. Now comes the moment of truth. Hoop up a piece of fabric that matches your final project material. Load your EXP file into the machine. Run a test.

Watch the machine as it stitches. Listen for thread breaks or unusual noises. When the test finishes, examine the result closely. Look for gaps in coverage. Check edges for crispness. Feel for puckering. Compare to your original design.

If something looks wrong, diagnose the cause. Puckering often means density is too high or underlay insufficient. Fuzzy edges may indicate pull compensation needs adjustment. Misaligned colors could mean registration issues in the digitizing.

Make notes and return to your software. Adjust parameters, export a new EXP, and test again. Repeat until the stitch-out meets your standards. This testing phase is where good digitizers become great.

Common Mistakes to Avoid

Even experienced digitizers make errors. Knowing what to watch for saves time and frustration.

Skipping underlay leads to poor registration and fabric shifting. Always include appropriate underlay for your fabric type.

Ignoring fabric characteristics causes pull compensation mistakes. Adjust settings based on what you are stitching, not generic defaults.

Using auto-digitize for complex designs produces mediocre results. Manual digitizing takes longer but delivers professional quality.

Forgetting to test wastes material and time. Test on scrap fabric before committing to production runs.

When Professional Help Makes Sense

Digitizing is a specialized skill that takes time to develop. If you need consistent, high-quality results for business, hiring a professional service can be cost-effective . Companies like Absolute Digitizing and Digitizing Buddy employ experienced digitizers who understand Melco machines and the EXP format. For a modest fee per design, you get a file that stitches perfectly the first time .

If you enjoy learning and want creative control, invest the time to master the tools. The satisfaction of creating beautiful embroidery from your own designs is real. But recognize that professional-level digitizing takes practice.
