At ZDigitizing, we handle complex digitizing daily, but for fundamental file viewing and conversion, we often recommend TrueSizer to our clients. This guide provides a straightforward, step-by-step walkthrough for using the software to convert and edit your embroidery files, ensuring they are ready for your machine.
Why Wilcom TrueSizer is a Practical Choice
Wilcom TrueSizer is a valuable tool because of its accessibility and core functions. As a free version of Wilcom’s professional EmbroideryStudio software, it provides capabilities that are genuinely useful for both hobbyists and small businesses. You can accurately view designs with a 3D stitch preview, resize them while preserving stitch density, and convert between nearly all major machine formats.
It operates on both Windows and macOS, making it a reliable part of any embroiderer's toolkit in 2025. Its primary benefit is providing a no-cost, professional solution for managing design files before you send them to your machine or to a service like ours for more advanced digitizing.
Getting Started with Wilcom TrueSizer
Before you can manage your files, you need to install the software. The process is simple and requires only a few minutes.
Downloading and Installing TrueSizer
First, navigate to the official Wilcom website and find the TrueSizer download page. You will need to select the correct version for your operating system, either Windows 10/11 or macOS Ventura/Sonoma. To get the download link, you must create a free Wilcom account; this is a one-time step that unlocks the software's full features. Once downloaded, run the installer and follow the on-screen instructions. After installation, launch TrueSizer and log in with your account to activate all functions, including file saving and conversion. No subscription or payment is needed.
System Requirements
TrueSizer is not demanding on system resources. It runs well on a computer with Windows 10/11, 4GB of RAM, and a 2GHz processor. For macOS 12 or newer, 8GB of RAM is recommended. You will also need about 500MB of available disk space and a screen resolution of at least 1366×768.
How to Convert Embroidery Files: A Step-by-Step Process
Converting a design file is necessary to ensure it is compatible with your specific embroidery machine. For example, Brother and Janome machines often use .pes and .jef files, while Tajima machines use .dst.
Step 1: Open an Embroidery File
Launch TrueSizer and go to File > Open. Navigate to the location of your embroidery design and select it. The file will load in the workspace, showing you a realistic 3D stitch simulation and a panel with the color sequence.
Step 2: Check the Design's Details
Before converting, review the file information displayed in the software. TrueSizer shows the total stitch count, the design's physical dimensions (height and width), and the number of color stops. This is a good time to confirm that the design will fit within your machine’s largest hoop, such as a 5×7 inch frame.
Step 3: Convert and Save in a New Format
To convert the file, go to File > Save As. A dialog box will appear where you can choose your desired machine format from the "Save as type" dropdown menu. For example, select .pes for Brother machines or .dst for Tajima. You may also see options to select a specific version of the file format, which is useful for older machines. Save the converted file to a folder or directly onto a USB drive for easy transfer. TrueSizer is built to maintain stitch data integrity, so the design quality is preserved during conversion.
How to Edit Embroidery Files in TrueSizer
TrueSizer allows for basic but essential edits. You can easily adjust a design's size, orientation, and colors to better suit your project.
Step 1: Resize the Design
First, select the design in the workspace. You can resize it by clicking Transform > Resize or by dragging the corner handles. It is important to check the Maintain Stitch Density box; this function tells TrueSizer to recalculate the stitches for the new size, which helps prevent gaps or bunched-up threads. Always make sure the final dimensions fit within your machine's hoop. As a general rule, avoid resizing a design more than 25% larger or smaller, as significant changes can degrade quality. For major size adjustments, it is better to have the design professionally re-digitized.
Step 2: Rotate or Mirror the Design
To change the orientation, use the Transform > Rotate menu to turn the design by a specific angle, such as 90 degrees. You can also flip the design with the Mirror Horizontal or Mirror Vertical options. This is particularly useful for creating matching left-and-right pieces for apparel.
Step 3: Modify Thread Colors
The Thread Colors panel lists the complete color sequence for the design. To change a color, select a specific color stop in the sequence and choose a replacement from the integrated thread charts from major brands like Madeira or Isacord. This helps you match the digital design to the physical thread colors you own.
Step 4: Save Your Edited File
After making your edits, go to File > Save to overwrite the existing file or, more safely, use File > Save As to create a new, edited version. Remember to save it in the format your machine requires.
Practical Tips for a Smooth Workflow
To use TrueSizer effectively, always preview your design in TrueView mode to see how the stitches will look. If you need to convert many files, you can select them all in the Open dialog to process them in a batch. Also, make it a habit to use the built-in hoop templates to visualize how your design will fit on your item. Finally, always keep a backup of your original design file before you begin editing.
