Embroidery file viewer for macOS
Preview the stitches.
Before you press Start.
Preview DST, PES, JEF and EXP designs, inspect their thread sequence and dimensions, then proof a whole folder without launching a full digitizing suite.
Inside the actual app
A readable preview before production.
ThreadView parses the actual machine file and renders its stitch path beside the format, stitch total, thread blocks, dimensions and compatibility audit. Every image here was captured from the native Release build.
Built for the real handoff
One focused app.
Four jobs done.
Finder triage
Recognize embroidery files before opening a larger production application.
Vendor handoff
Confirm that a received design has plausible size, colors and stitches.
Folder inventory
Turn mixed machine formats into a visual contact sheet and searchable CSV.
DST copy
Create a new DST file only after compatibility preflight passes.

From first record
to finished handoff.
Add designs
Open one file or a folder containing DST, PES, JEF and EXP embroidery designs.
Inspect the stitch plan
Review the rendered path, color blocks, stitch count, dimensions, jumps and color changes.
Create review copies
Export a contact sheet, catalog CSV, SVG preview, DST copy or batch ZIP while keeping every source untouched.
Focused by design
Useful depth.
No account clutter.
Native binary parsers
Read DST, PES, JEF and EXP structures directly instead of renaming extensions or relying on cloud conversion.
Embedded Quick Look extension
Give Finder a thumbnail provider for the embroidery formats registered by ThreadView.
Thread sequence inspection
See each color block in order with its source color or a stable fallback when a format has no palette.
Production preflight
Check design bounds, stitch totals, jumps, color changes and whether a new DST copy can be created safely.
Batch proof package
Generate a contact-sheet PDF, design inventory CSV and SHA-256 manifest for client or machine-room review.

Questions, answered
ThreadView FAQ
Which embroidery file formats can ThreadView open?+
The current native parser opens DST, PES, JEF and EXP embroidery files and shows the stitch path, design bounds, stitch count and thread sequence.
Does ThreadView add Quick Look previews on Mac?+
Yes. The app bundle includes a Quick Look thumbnail extension for supported embroidery files. macOS registers the extension after the app is installed and opened.
Can I preview a folder of embroidery files?+
Yes. Add multiple designs to the catalog, switch among them and create a contact-sheet PDF, CSV inventory and manifest-backed ZIP for the batch.
Does ThreadView edit embroidery stitches?+
No. ThreadView is intentionally a viewer and preflight tool. It helps you inspect files and create review copies without pretending to replace full digitizing software.
Can it convert an embroidery file?+
The MVP can create a new DST copy when the parsed stitch stream and bounds pass conversion preflight. The original source file is never overwritten.
Are my designs uploaded?+
No. Parsing, rendering, audit and export run locally in the current Release build, with no account required.
How much will ThreadView cost?+
The planned launch price is US$24 as a one-time purchase for one Mac. Checkout will open after signing and Apple notarization are complete.
