Size it before you hook it
Enter your gauge and see the finished width and height as you chart — or start with the size you want and let Crochetius calculate the stitch count.
Public beta
The professional crochet chart maker — without the workarounds.
Create accurate, professional crochet charts with tools built specifically for crochet designers.
Free during public beta · No card · Your work stays accessible
Built for crochet charts — not adapted for them.
Everything you need to create professional crochet charts, without the workarounds other tools leave you with.
Turn a photo into a graphghan
Upload your image, crop and resize it, remove the background, and choose your color palette — all without leaving Crochetius for another program.
Create shells, fans, and real angles
Anchor stitches between points and place them at true angles. Build shells, fans, and angled stitch combinations right inside your chart.
Add a motif without rebuilding your chart
Place an image over an existing chart, then scale, rotate, and position it exactly where you need it — without starting over just to add one element.
Edit like you expect to
Work with layers, flood fill, pattern tiles, mirroring, and 100+ levels of undo — the familiar editing tools that make designing faster.
Use every symbol — or create your own
Start with a full library of standard crochet symbols. Need something different? Create or paste your own symbol, set its anchors, and reuse it throughout your charts.
Add the details that make a chart easy to follow
Place row numbers, notes, arrows, brackets, and other annotations exactly where your readers need them.
Let the legend build itself
Every symbol you use is automatically added to the legend and stays up to date as your chart changes.
Export PDFs made to be printed
Create multi-page tiled PDFs with an assembly map and your gauge in the header, or export as PNG — no manual page setup in another program.
And we're just getting started.
Crochetius is already built for serious chart making.
Here's what we're working on next:
- Written row-by-row instructions generated from your chart
- Turn written instructions back into a crochet chart
- Accurate, maintained color palettes from real yarn brands
- Folders and tags to organize your projects
- Tracker mode for following charts while you crochet
- Charts worked in the round
- Branded PDF templates for pattern designers
Crochetius is in public beta. Testers get the whole editor free, with no card and no feature tiers. Paid plans arrive later — and when they do, the charts you have already made stay accessible.
Before you start.
Is Crochetius free?
Yes. During the public beta the full crochet chart editor is free, no payment details are required, and you can start charting without an account. Paid plans are planned for later; anything you make during the beta stays accessible.
Do I need to install anything?
No. Crochetius runs in a modern desktop browser — Chrome, Edge, Firefox or Safari. A tablet mode for following a chart while you crochet is on the roadmap but is not built yet, so a laptop or desktop is the right tool for designing today.
Does it handle knitting or cross stitch?
No, and that is deliberate. Crochetius is a crochet chart maker only. Crochet has its own geometry — stitches of different heights, symbols that span more than one cell, work built outward rather than in rows — and tools that serve ten crafts at once end up serving none of them properly.
Can it write out row-by-row instructions?
Not yet. Written instruction generation, including repeat detection and US/UK terminology, is the next major feature. Today you design the chart, annotate it, and export it as a multi-page PDF or PNG with the legend included.
Can I turn a photo into a blanket pattern?
Yes. Import a photo, crop and resize it, remove the background, reduce it to a palette you choose, and it becomes an editable graphghan chart. You can also drop a photo or motif onto a chart you have already sized instead of starting over.
How big a chart can I make?
Charts can be up to 500 stitches wide and 500 rows tall. That covers most blanket-scale graphghans and symbol charts in the browser.
