WHY PEDIGREECHARTMAKER
Everything a family health chart needs
Export in five formats
Sharp SVG vectors, high-res PNG, print-ready PDF pages, re-editable JSON projects, and one-click printing.
Standard pedigree symbols
Affected, carrier, proband, deceased, consanguineous, twins, adoption, stillbirth, pregnancy — all included.
Auto layout, manual control
One click arranges generations top-to-bottom; drag anyone to fine-tune, or pin people in place.
Templates for inheritance
Start from dominant, recessive, X-linked, mitochondrial, or Y-linked pedigrees — then edit freely.
Keyboard and screen-reader ready
Full keyboard shortcuts, a semantic chart outline, and every control has a text alternative.
HOW IT WORKS
From blank page to printed chart in three steps
-
Add people
Pick a template or start blank, then add parents, partners, and children with one click — or use Quick Build and answer plain-language questions.
-
Mark health details
Shade people as affected by any trait, mark carriers, deceased, probands, twins, adoptions, and more from the inspector panel.
-
Export and share
Auto-layout the chart, then export print-ready SVG, PNG, or PDF — or save the project file to finish later.
# Quick Build — say it in plain language
> A man and a woman have a son and a daughter.
> The son is affected with cystic fibrosis.
> The mother’s brother is also affected.
✔ 7 people added, 3 unions, proband marked
✔ Autosomal recessive pattern hint: both parents are carriers
Try Quick Build →WHO IT’S FOR
Built for classrooms, clinics, and families
Genetics classrooms
Students practice autosomal dominant and recessive, X-linked, and mitochondrial patterns on real notation with instant visual feedback.
Clinics and counselors
Draw a family health history during a consultation, print it for the chart, and keep sensitive data on the patient’s own device.
Family historians
Record several generations of relatives, health conditions, and relationships in a clean, printable tree you can revisit anytime.
STARTER TEMPLATES
Begin from a real inheritance pattern
Every template opens as a fresh, editable project with new IDs — nothing shared, nothing saved to us.
Three-Generation Pedigree
Grandparents, parents, and children with a proband.
Autosomal Dominant Pedigree
Trait appears in every generation; one affected parent usually has affected children.
Autosomal Recessive Pedigree
Unaffected carrier parents can have an affected child; the trait may skip generations.
X-Linked Recessive Pedigree
Mostly affected males; carrier mothers pass the trait to sons.
Mitochondrial Inheritance Pedigree
Only mothers pass the trait; all children of an affected mother are affected.
Twins Pedigree
Monozygotic and dizygotic twins with standard bars.
Adoption Pedigree
Birth family and adoptive family brackets in one chart.
Y-Linked Pedigree
Only males are affected; affected fathers pass the trait to all sons.
STANDARD NOTATION
Symbols your readers already know
PedigreeChartMaker follows the human pedigree notation used in genetics education and medical records — squares and circles, shaded for affected, dots for carriers, bars for twins, and dotted lines for adoptions. No symbol set to configure, no guessing for readers.

FAQ
Questions, answered
Is PedigreeChartMaker really free?
Yes. The maker, all templates, every export format, and Quick Build are free with no account and no trial. There are no file or person limits.
Do I need to create an account?
No. Your project is saved in your browser’s local storage. You can export it as a .pedigree.json file to back it up or open it on another device.
Where is my data stored?
On your device only. Nothing is uploaded to our servers — there is no server involved in editing. The contact form is the only thing that sends data, and only if you choose to use it.
Can I make a pedigree with more than three generations?
Yes. Add as many generations as you need — parents, grandparents, great-grandparents, and beyond. Auto layout re-flows the whole chart in one click.
Which inheritance patterns do the templates cover?
Autosomal dominant, autosomal recessive, X-linked recessive and dominant, mitochondrial, and Y-linked — plus relationship templates for twins, adoption, and a blank canvas.
What file formats can I export?
SVG for vectors and editing, PNG for sharing at any scale, PDF for print, and .pedigree.json to continue editing later. You can also print directly from the browser.
Is the notation standards-compliant?
The symbols follow the conventional human pedigree notation taught in genetics courses and used in clinical records: squares for males, circles for females, shading for affected individuals, dots for carriers, bars for twins, and dashed lines for adoptions.
Does it work on a phone?
Yes. On small screens the editor switches to a bottom-bar and sheet layout designed for touch, and exports still produce full-size, print-ready files.
