Free online PEC to PNG converter

Source format: PEC

PEC is an embroidery design file format commonly associated with Brother home embroidery machines and software. It stores stitch data, thread color information, and design instructions rather than a normal image. Embroidery users, digitizers, and machine owners use PEC files to transfer designs to compatible machines or to edit designs in embroidery software. Typical use cases include machine embroidery, design previewing, and stitch planning.

Target format: PNG

PNG is a widely supported raster image format that uses lossless compression. It is ideal for previews, sharing, web use, documentation, and preserving sharp edges and transparency. Compared with PEC, PNG is not an embroidery format; it is a visual representation of the design, usually as a rendered preview or stitch simulation.

How to perform the conversion

The best way to convert PEC to PNG is to use embroidery software that can open PEC files and export or save a rendered image. A practical desktop option is Wilcom TrueSizer or another embroidery viewer/editor that supports PEC. If you only need a quick preview image, you can also convert the file on 101convert.com for free without installing any software.

1. Open the PEC file in your embroidery software.
2. Check that the design displays correctly, including colors and orientation.
3. Use the export or save-as image function, if available, and choose PNG as the output format.
4. If the software offers preview rendering options, enable them so the PNG shows the stitched design rather than raw stitch data.
5. Save the resulting file, for example as design.png.

In some programs, the menu path may look like File → Export → Image or File → Save As, followed by selecting PNG. If your embroidery software cannot export directly to PNG, open the PEC file and use a screen capture tool as a fallback, though direct export is preferable for better quality.

Quality, compatibility, and limitations

The main limitation is that PEC is not a picture format, so converting it to PNG creates only a visual rendering of the embroidery design. The PNG will not contain editable stitch data, machine commands, or embroidery metadata. Quality depends on the software’s rendering engine, zoom level, and export settings. A low-resolution export may look blurry, while a higher-resolution export will preserve more detail.

Also note that thread colors in PEC files may be interpreted differently by different programs, so the PNG preview may not exactly match the final stitched result on fabric. If the PEC file uses special stitches, trims, or machine-specific features, those details may not be visible in the PNG at all. For best results, use software that is known to support Brother PEC files accurately and export at a sufficiently large image size.
