Stitch Slop
Stitch Slop is a machine-embroidery digitizer that runs in a desktop web browser. You draw or trace a design, choose how each part is stitched, and export a file your embroidery machine can sew.
There is nothing to install. Designing and exporting never require an account.
Open, view and convert embroidery files
Most embroidery files can only be opened by the software that came with a machine. Stitch Slop opens them in your browser, with nothing to install and no account.
View an embroidery file
Drag a PES, DST, JEF, EXP, VP3, XXX or other embroidery file onto the page to open it. You see every stitch in its thread colours, and you can watch it stitch out in the order your machine will sew it, or look at it in a simulated 3D thread view.
See what's inside a ZIP of designs
Designs bought online often arrive as a ZIP holding the same design in many formats and sizes. Drag the ZIP onto the page. Stitch Slop lists the designs inside by size, lets you tick the ones you want, and tells you about any file it couldn't read and why. Nothing is uploaded: the ZIP is opened in your browser.
Convert an embroidery file to another format
Open a file, then export it in the format your machine uses: PES to DST, DST to JEF, EXP to PES, and so on across all 21 formats listed below. If the new format can't store the exact thread colours, Stitch Slop matches the nearest thread and tells you when the match is poor.
Resize, recolour or add to a design
Once a file is open you can change thread colours, add lettering, or combine it with other designs before exporting. Machine files are made of stitches rather than shapes, so large size changes are best done from the original artwork.
What it does
- Draw or import artwork. Open SVG or DXF files, or trace over a photo or drawing placed behind the design. The image is only a guide and is never stitched.
- Choose the stitches. Satin, satin column, satin fill, tatami, running, bean, redwork, braid, motif, contour, meander, fur and sketch, each with its own settings.
- Trace Image. Turn a picture into a few thread colours, with one fill per region, preview it, then add it in one step. Or use the Pick tool: click a region of the image to turn it into a fill.
- Lettering. Type text and place it as editable stitches. You can also digitize your own stitch font.
- Patches. Build a patch with a tatami body and a merrow border around your art.
- See it before you sew it. Watch the design stitch out in machine order, check it in a simulated 3D thread view, and control the sewing sequence.
- At the machine. On a phone or tablet, signed in, the run sheet shows colour order, stitch counts, size, the smallest hoop that fits, and an estimated run time.
Machine formats
Stitch Slop exports 21 formats:
- Tajima DST
- Brother PES and PEC
- Melco and Bernina EXP
- Janome JEF, SEW and JPX
- Pfaff and Husqvarna VP3
- Pfaff PCS, PCD, PCQ and PCM
- Husqvarna SHV, VIP and HUS
- Singer XXX and CSD
- Elna EMD
- Happy TAP
- Barudan U01
- ZSK Z00
It opens all of those, plus Tajima TBF and ZSK DSZ. Formats that don't store thread colours, such as DST, get a colour file written alongside. Where a format can only store a palette, Stitch Slop matches the nearest thread and warns you if the match is poor.
Stitch Slop is new. Its files are checked against those written by established digitizing software, but please test-sew a design before a production run.
Accounts
An account is optional. Signing in uses an emailed link or code, with no password. It saves your designs to your account, opens the design library of patch and badge shapes, and enables the run sheet on phones and tablets.
Signed out, Stitch Slop keeps nothing you make in the browser. Download your project to keep it.
AI agents
An AI agent running on your own computer, such as Claude Code, can read and change the design in your open tab when you switch on Agent Connections. See connecting an agent.
Problems and feedback
Use Report bug in the app. It sends the design and a picture of the canvas so the problem can be reproduced.
