Documentation ​

Follow the Project Site to know all the SVG tools: SVG Text Editor, Shell Extensions (Preview Panel, Thumbnails and Context menu) and the SVGToPNG command-line tool.

Features ​

  • Supports Windows 10 and 11 (for 32 bits and 64 bits).

  • Themes (Dark and Light) according to user preferences of Windows Theme

  • Integrated also with other Shell Applications (like XYplorer)

Setup using the Installer ​

Click to download the SVGShellExtensionsSetup.exe located also in the Release area. The Installer works both for 32 and 64 bit system.

SVG Setup_Program

For a clean Setup close all the windows explorer instances which have the preview handler active or the preview handler was used (remember the dll remains in memory until the windows explorer was closed).

SVG Text Editor ​

A useful Text editor with preview of SVG Image:

SVG Text Editor Dark

Color palette: under the editor a panel shows all the colors used by the SVG, with the number of occurrences of each one. Colors are found in the presentation attributes (fill, stroke, stop-color, flood-color, lighting-color, color, solid-color), in style attributes and in <style> blocks, written as hex (#rgb, #rgba, #rrggbb, #rrggbbaa), rgb(), rgba(), hsl(), hsla() or color names; the same color written in different ways is shown once.

  • Click on a color to highlight all its occurrences in the text, then move between them with Alt+Right / Alt+Left or with the arrow buttons of the palette.
  • When the caret is on a color value, the corresponding color is marked in the palette.
  • Double-click on a color to replace the color value under the caret (keeping its notation and opacity), or to insert it at the caret position as #RRGGBB.
  • Right-click on a color to replace all its occurrences with another color (one single undo), to select all its occurrences with multiple carets, or to copy its value.
  • Add your own colors to the "Custom" section with the + button (color picker) or from the context menu: they are kept for all files and shared with the custom colors of the color picker.
  • The hint of each color shows its value, the properties using it and its opacities.
  • The palette can be hidden in the Settings ("Show color palette under the editor").

Automatic updates ​

The SVG Text Editor checks if a new version is available on GitHub, then downloads and installs it:

  • Automatic check: at startup, once every n days (7 by default), in background; it can be disabled or its interval changed in Settings - Updates.
  • Manual check: with the "Check for updates" button of the About dialog.
  • When a new version is available the editor asks to download it: the About dialog shows the progress of the download (that can be stopped), then the editor starts the Setup and closes itself.

COMMAND LINE TOOLS ​

svg_png Tool

SVGToPNG is a command-line utility for batch converting SVG files to PNG images.
