Free online PDF to PES converter

Brother, Baby Lock, and compatible embroidery machines require PES files because they read stitch instructions rather than printable PDF pages. The conversion is therefore a digitizing process that turns artwork into stitches, color changes, and machine settings.

What the PDF format is

PDF is a page-description format used for documents, print layouts, logos, diagrams, and scanned artwork. Applications such as Adobe Acrobat, Illustrator, Inkscape, CorelDRAW, LibreOffice, and scanner software create PDFs. A PDF can contain vector paths, raster images, text, transparency, and multiple pages, but it normally contains no embroidery information such as stitch direction, density, underlay, pull compensation, trims, or hoop placement.

A vector PDF provides the best source geometry because its shapes can be imported or traced without pixelation. A scanned or image-only PDF requires manual tracing or cleanup. Gradients, shadows, photographs, transparency, very thin lines, and tiny lettering usually need simplification before digitizing.

What the PES format is

PES is a machine-embroidery format associated primarily with Brother and compatible Baby Lock machines. It stores stitch coordinates, stitch blocks, color-change information, thread-color metadata, and design or machine data used by compatible embroidery software and controllers.

PES is not an image, document, or editable vector format. The same logo can produce different PES files depending on fabric, hoop size, thread, stitch type, density, underlay, and object order. PES revisions and supported features vary between machine models.

How to convert the artwork

Free desktop workflow: Inkscape and Ink/Stitch

1. Install current versions of Inkscape and the Ink/Stitch extension from their official sources. Ink/Stitch is digitizing software, not a filename or container converter.
2. Open the PDF in Inkscape with File → Open. Import editable vector content when prompted. For a scanned PDF, import the image with File → Import, then trace it manually or use Path → Trace Bitmap as a starting point.
3. Remove page backgrounds and unrelated elements, convert text to paths with Path → Object to Path, close open shapes, and simplify unnecessary nodes. Check the physical dimensions in millimeters and choose a hoop that fits the design.
4. Assign embroidery objects in Ink/Stitch. Use running stitches for outlines and fine lines, satin columns for suitable narrow borders and lettering, and fill stitches for broad areas.
5. Set stitch density, stitch length, stitch direction, underlay, pull compensation, start and end points, thread colors, and stitch order. Order objects to reduce jumps and prevent later stitches from obscuring important details.
6. Open Ink/Stitch's preview or visualization and inspect stitch direction, jumps, trims, color changes, estimated stitch count, and final dimensions. Correct gaps, excessive density, and details too small to sew.
7. Use Ink/Stitch's export command, select PES, and save the result as design.pes. Open it in compatible machine software before transferring it to the machine.

Commercial desktop workflow: Brother PE-Design, Hatch, Wilcom, or Embird

1. Import the PDF through the software's artwork-import command. If direct PDF import is unavailable, open the PDF in Inkscape, Illustrator, or CorelDRAW and save clean vector artwork as SVG or another format supported by the embroidery program. Use a high-resolution PNG only for raster artwork.
2. Use automatic digitizing as a starting point, then correct object boundaries, stitch angles, densities, underlay, overlaps, and sequencing manually.
3. Set the target hoop dimensions, finished design size, garment orientation, thread chart, and machine settings. Choose a PES revision supported by the target machine when the software provides that option.
4. Run the stitch simulator, check color changes, jumps, stitch count, and design dimensions, then export through the software's embroidery-file command.
5. Copy the PES file to supported USB media or transfer it with the manufacturer's software. Test-stitch it on similar fabric with the intended stabilizer, needle, and thread.

Online conversion

You can use the built-in converter on 101convert.com to convert a file for free without installing software. Upload the PDF, choose PES as the output format, and download the result when processing finishes.

Automated conversion is most reliable with simple, clean artwork. It may not make appropriate decisions about stitch types, density, underlay, pull compensation, sequencing, or fabric behavior. Review the generated dimensions, color blocks, and stitch simulation when available; complex logos and lettering usually require manual digitizing in embroidery software.

Quality and compatibility limits

Preserve the intended physical size during import and verify the width and height before export. A design must fit the actual hoop; an oversized design may require separate sections, alignment marks, and multiple hoopings.

Dense overlapping fills can cause puckering, thread breaks, or fabric damage. Lightweight fabrics generally need different density and stabilizer settings from heavy fabrics. Test-stitching is required because a PES file can open correctly while still sewing poorly.

Check the machine's supported PES revision, maximum hoop area, stitch-count limit, color-change limit, and file-transfer requirements. Older machines may reject newer PES variants or unsupported metadata. If necessary, reopen the design in compatible embroidery software and export an older PES revision.

Keep the original PDF and the editable digitizing project. The exported PES file contains stitches rather than the original vector shapes, so it generally cannot be edited back into the source artwork.
