StitchKeep-ready · Check a chart

Check a chart

See how StitchKeep's chart marker will read your PDF: the grid, the symbols, the legend and how pages join. This page runs the same checks as the app, inside your browser. Your file never leaves your device; nothing is uploaded or stored.

What the checks mean

A chart is StitchKeep-ready when nothing fails. Warnings are recommendations: the chart still works, but stitchers will do a step by hand. Each check matches a section of the chart spec, and the checklist sums them up.

Want to mark this chart as you stitch?

StitchKeep opens your PDF chart on iPhone, iPad or Mac and lets you tap to mark stitches, highlight one symbol and park threads. It's free, with no ads and no account. Join the beta to get it before the App Store.

Checks the first 40 pages for chart grids and the first 12 for a legend. The PDF reader is PDF.js (Apache 2.0), served from this site.
