About SurgPathPic

A browser-based photo annotation tool built for surgical pathology and veterinary practice. Calibrated grid, ruler, polygon area, angle, outlines, arrows, and labels - every clinical tool, always available, in one editor.

What it does

SurgPathPic opens a photo in your browser and gives you the clinical annotation tools consumer design software has never bothered to build:

Calibrated to real-world millimeters - two clicks of known distance and the grid, ruler, and polygon area all read in real mm or cm.
Every tool, always - no mode picker. Grid, ruler, polygon area (mm²/cm²), angle, outlines, arrows, shapes, and labels are in the same editor every time.
Auto-numbered regions - click cells to mark cassettes, sections, and sampled regions. Composite grouping and per-cell color coding included.
Multi-page case PDF - one page per photo, with the case ID, photo number, and creation timestamp on every page.
Branded exports with institutional logo and case header, in PNG and multi-page PDF - full annotated map, clean photo with logo, or composite grid.

Who it's for

Laboratory

Surgical pathology

Pathologists, pathologists' assistants, and residents in the gross room - cassette mapping, margin annotation, gross and micro documentation.

Laboratory

Autopsy

Organ-by-organ documentation with calibrated measurement, a consistent case header, and a multi-page PDF for the file.

Veterinary

Small animal, equine, exotic

Same calibrated tools, animal-aware vocabulary - from cat masses to bovine necropsy to avian findings.

Research

Teaching & manuscripts

Teaching sets, case atlases, board prep, IRB-eligible documentation with consistent institutional branding across every export.

Privacy by architecture

SurgPathPic is built so that patient images never leave your computer. The annotation, calibration, grid math, rendering, and export all run inside your browser. We have no servers that touch your specimen photos because there is no need for any - the work happens locally. The only information that reaches us is the small amount required to operate accounts: your email and subscription status.

Read the full privacy policy for specifics, including what data we do and don't collect, who our service providers are, and your rights.

Institutional and IT teams

If your institution's IT or compliance team needs information about how SurgPathPic handles data before allowing access on your network, please share the privacy policy with them. The short version: nothing flows from your computer to ours except the email address you signed in with. No PHI ever transits or is stored on SurgPathPic infrastructure.
