# Free PCM Viewer

Canonical page: https://embroideryfileconverter.com/pcm-viewer

Open a PCM embroidery file online to inspect its stitch preview, dimensions, thread sequence, colour changes, jumps and trims. No account required.

## What is a PCM file?

PCM is a machine embroidery format containing stitch commands and production data. Depending on the format and the software that created it, the file may also preserve design dimensions, colour changes, thread information, jumps, trims and machine-specific commands.

## What this viewer checks

The viewer verifies that the filename uses the `.pcm` extension, checks the supported file structure, sends the file to the restricted embroidery engine, parses its actual commands and creates both raster and vector stitch previews. It reports:

- design width and height;
- stitch count;
- thread count and available thread colours;
- colour-change count;
- jump count;
- trim count;
- end-command count.

## How to view a PCM file

1. Open the [Free PCM Viewer](https://embroideryfileconverter.com/pcm-viewer).
2. Select or drop one `.pcm` file up to 50 MB.
3. Choose **Inspect PCM file**.
4. Review the stitch preview, dimensions, thread sequence and production metrics.
5. Open the larger viewer to zoom, pan or download the SVG or PNG preview.

No account is required and viewing a file does not consume a free processing job or purchased credit.

## Format limitation

PCM is accepted as a source format; reliable open-source PCM writing is not available.

## Important limitations

The preview represents the stitch commands stored in the PCM file; it is not a photograph of the final sew-out. Fabric, stabilizer, thread, tension, needle, density and machine settings affect physical production. Always test stitch an unfamiliar design before using final garments or materials.

## Next steps

This format can be opened and used as a conversion source, but the platform does not offer an unverified PCM output writer.
