Why a JPG does not become a PES just by changing the extension
JPG is the format of phone photos, of screenshots that arrive over WhatsApp and of almost everything downloaded from a website. It compresses the image by losing detail, so halos and dirty pixels appear around letters and edges and have to be cleaned up before digitizing.
A PES file, on the other hand, is a list of instructions for the machine: move the needle, stitch, jump, trim and change thread. Going from one to the other is digitizing: redrawing the design as stitch objects and deciding the type, direction and order for each area.
How we turn the JPG to PES, step by step
An image is a drawing; an embroidery file is a recipe for the machine. Getting from one to the other takes interpretation, which we do in five steps.
1. Clean up and simplify the image
We start from the JPG and remove noise, blurry edges and gradients. A thread is a single color, so the design is reduced to the shades that will actually be stitched (in a logo, usually between 1 and 8). Lines thinner than 1 or 1.5 mm are redrawn thicker, because thread cannot be thinner than that.
2. Decide final size, garment and fabric
A stitch has a fixed size; it does not scale like an image. That is why we ask how big the embroidery will be and what fabric it goes on: a stretch polo, a cap or a towel need different densities and underlays. With that information we digitize the design for that specific use.
3. Choose the stitch type for each area
We redraw the design as objects and assign each one a stitch, with its direction and density (the spacing between stitches is usually around 0.4 mm).
| Stitch | Used for | How it works |
|---|---|---|
| Running | Outlines, thin lines and small details | A simple, continuous stitch. It is the only one that can draw lines thinner than 1 mm. |
| Satin | Lettering and narrow shapes, 1 to 7 mm wide | Parallel stitches laid very close together for a smooth, glossy finish. If the area is wider, the thread snags and it switches to fill. |
| Fill (tatami) | Large areas of color | Rows of short, staggered stitches that cover wide surfaces with an even texture and no long loose threads. |
4. Technical adjustments that prevent puckering
- Underlay: base stitches underneath that hold the fabric and lift the satin so it does not sink in.
- Pull compensation: thread tightens the fabric as it is stitched, so we widen the shapes slightly to make the final result match the size of the original.
- Order and path: we stitch from background to detail and link nearby areas to reduce thread jumps and color changes.
- Tie-ins and trims: every section starts and ends secured, and trims are marked wherever there are long jumps.
5. Simulate, export and check
Before delivering we run the design through the stitch simulator: we look at the sequence, the stitch count and the thread changes, and fix whatever does not fit. Then we export it to PES, check that it opens and that the simulation matches what we agreed, and send it to you with the color sheet.
The PES format
PES is the Brother and Baby Lock format, the most widespread on home embroidery machines. Besides the stitches it stores the colors, a thumbnail of the design and, inside, a PEC block that older machines read.
There are several PES versions. Modern machines read them all, but some older ones only understand early versions; if your machine is a few years old, tell us the model and we will deliver the compatible version.
| Brand | Use |
|---|---|
| Brother | Innov-is, PE and PR series (home and semi-industrial) |
| Baby Lock | home and multi-needle embroidery machines |
| Bernette | embroidery models in the Bernette range |
The maximum size is set by your machine’s hoop (from 10 × 10 cm on entry-level models to 20 × 30 cm or more on multi-needle ones). If the design does not fit, the machine will not open it.
How to prepare the JPG before sending it
- Send the largest version you have: from 1000 px on the short side we can work comfortably.
- Avoid screenshots of a photo or images forwarded several times through messaging apps: every forward compresses again and wipes out detail.
- If the logo has a colored background, mention it in the notes: JPG has no transparency, and we need to decide whether the background is stitched or not.
- If you have the same design as a PDF, SVG or AI file, send that instead of the JPG.
In this case: From the JPG we take sample colors and match them to real threads; in PES they are stored inside the file itself.
How we convert it
- We review your fileWe check the JPG, clean up the edges and reduce the colors to real threads.
- We set size and fabricStitch density depends on the final size and the garment, so it is decided before digitizing and never rescaled afterwards.
- We digitize by handWe trace every area and choose the stitch type (running, satin or fill), direction, density, underlay and pull compensation.
- We simulate the embroideryWe check the sequence in the stitch simulator to remove unnecessary jumps and trims.
- We send it to youYou get the .PES file with a preview and a sheet with colors, stitch count and dimensions.
What you receive
A .PES file compatible with your model, a preview of the design and a sheet with colors, stitch count and dimensions.
If you also need the design in another format (for example for a workshop with an industrial machine), ask for it in the notes.
Frequently asked questions
Can a JPG be converted to PES for free and automatically?
There are automatic converters, but a JPG contains no stitches: the software guesses direction, density and order, and the result tends to pucker the fabric, break thread or leave letters unreadable. They work as a draft for very simple designs. To embroider a real garment, the PES must be digitized or reviewed by hand.
Which machines read the PES format?
Brother: Innov-is, PE and PR series (home and semi-industrial). Baby Lock: home and multi-needle embroidery machines. Bernette: embroidery models in the Bernette range. If you are not sure, put your machine model in the notes.
Is my JPG too small or blurry to embroider?
It is almost never an insurmountable problem. The JPG only serves as a template: the digitizer redraws every shape on top of it, so a slightly blurry image can be worked with. What cannot be invented is a detail you cannot see; if there is unreadable text, write it in the notes.
Which PES version do I need for my Brother?
If your machine is from the last few years, any recent version works. On older models an early PES version is better; that is why we ask for the machine model in the notes and deliver the version it reads.
How much does it cost to convert a JPG to PES?
€5 (about $6) per design, and we send it to you in under 24 hours. If your design needed anything out of the ordinary, we will let you know before starting.
