jupyterlab_export_svg_as_png_extension

[!TIP] This extension is part of the stellars_jupyterlab_extensions metapackage. Install all Stellars extensions at once: pip install stellars_jupyterlab_extensions

Copy or export any SVG graphic in JupyterLab as a high-quality PNG image. Right-click on any SVG element - whether it's a chart output, a diagram, or an inline graphic - and choose to copy it to the clipboard as PNG or save it as a PNG file.

Full disclosure: SVG is a perfectly fine format that nobody asked to be converted. But sometimes you need a PNG for a slide deck, a report, or that one colleague who insists on pasting images into Word documents. This extension won't judge. It just converts.

Features

• Copy SVG as PNG - Right-click any SVG in a notebook output or document and copy it as a PNG to the clipboard
• Save SVG as PNG file - Download any SVG as a high-quality PNG file with a deterministic filename
• Theme-aware export - Resolves @media (prefers-color-scheme) CSS in SVGs with configurable mode: follow JupyterLab theme (system), or force light/dark
• Configurable output width - Set the PNG width in pixels (64 to 8192, default 1920/Full HD); height scales proportionally to preserve aspect ratio
• Background color options - Export with transparent, white, black, or custom background color
• Works everywhere - Context menu appears on SVG outputs, markdown previews, HTML rendered content, and SVG files opened directly
