EXP File Viewer
Open and preview Melco EXP files free — stitch count, size and color blocks.
Quick answer: An EXP file is Melco's native machine-embroidery format, also read by Bernina machines. The free viewer below decodes it in your browser and shows the stitch count, size and a stitch-path preview — no software install, no upload.
Open a Melco .EXP embroidery file directly in your browser to check its stitch count, size, color blocks and a stitch-path preview. Parsing happens locally — the file is never uploaded.
EXP is Melco's native machine format, also read by Bernina machines. Because it stores only raw needle movements with no preview image, checking a file normally needs embroidery software — this viewer replaces that for quick checks.
How it works
- Drop the file — it is parsed byte-by-byte in your browser and never uploaded.
- See the stitch count, design size, color changes, and jump/trim counts read from the actual stitch data.
- Preview the stitch paths on a zoomable canvas, color block by color block, and export the preview as a PNG.
Good to know
- Stitch files don't store thread colors (DST) or store only palette hints (PES) — preview colors are for separating color blocks, not thread matching.
- The preview draws stitch paths, not simulated thread — actual sewn texture, density and pull depend on fabric and stabilizer.
Frequently asked questions
Is my EXP file uploaded anywhere?
No — it's decoded entirely in your browser, so the design never leaves your device.
Why does my EXP file show no color information?
The EXP format records color-change stops but not which threads to use — the operator assigns real threads at the machine. Our preview colors just separate the blocks.
