napari-svg

What it is and what it does

Napari-svg is a napari plugin that adds SVG export capability to the napari image viewer. It allows users to save their visualizations—including image data and annotations—as scalable vector graphics files, which is useful for publication-quality output, further editing in vector graphics software, or integration into documents.

The plugin depends on imageio, numpy, and vispy (napari's visualization backend) and is designed to integrate seamlessly into napari's file export workflow. It is actively maintained, supports Python 3.9 through 3.12, and carries no known security vulnerabilities.

Use it for:

• Export annotated microscopy images from napari as vector graphics for publication in scientific papers
• Save napari visualizations with overlaid shapes or points as SVG for further editing in design software
• Generate scalable diagrams from napari's layer-based visualizations without rasterization artifacts
• Preserve annotation data in a portable, editable format when sharing napari analysis results

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Napari-svg is a plugin that exports image data and annotations from napari visualizations as SVG files, enabling vector-based output from the napari image viewer.

Yes, if you use napari and need SVG export. The plugin has low install friction, is actively maintained, carries no security issues, and integrates directly into napari's export workflow. It is worth installing for any napari user who regularly needs vector output or publication-ready graphics from their visualizations.

Install

napari-svg on PyPI

pip install napari-svg

uv add napari-svg

poetry add napari-svg

Installing napari-svg

Before you install

Low install friction with a pure Python wheel and only three runtime dependencies (imageio, numpy, vispy). The package is actively maintained with a recent commit on 2026-07-01 and receives regular updates.

License in practice

Distributed under the permissive BSD-3 license, allowing free use, modification, and distribution with minimal restrictions.

Quickstart

pip install napari-svg

import napari
from napari_svg import svg_writer

# napari-svg integrates as a plugin; use napari's File > Export as SVG menu or call the writer directly

Requires napari to be installed separately; napari-svg functions as a plugin within the napari ecosystem.

Verify before relying

• What specific napari layer types (image, shapes, points, etc.) are supported for SVG export
• Whether the plugin preserves layer properties like opacity, blending modes, or color maps in the SVG output
• Performance characteristics when exporting large or complex multi-layer visualizations
