Window's shell script to quickly convert SVG's to PNGs

theoryshaw

Wanted to share the following Window's shell script as a quick way to convert SVG's to pngs, using inkscape...

@echo off
setlocal

REM Set input and output file paths
set "input_file=%~1"
set "output_png=%~dp1%~n1.png"

REM Log file
set "log_file=%~dp1conversion_log.txt"
> "%log_file%" (
    echo Starting conversion...
    echo Input file: "%input_file%"
    echo Output PNG: "%output_png%"
)

REM Process the SVG file with Inkscape
echo Processing "%input_file%" with DPI 150... >> "%log_file%"
inkscape "%input_file%" --export-type="png" --export-filename="%output_png%" --export-dpi=150 --export-background=white >> "%log_file%" 2>&1

REM Check if PNG conversion was successful
if exist "%output_png%" (
    echo Successfully converted to PNG: "%output_png%" >> "%log_file%"
    echo Conversion complete: "%output_png%" >> "%log_file%"
) else (
    echo Error occurred during PNG conversion. Please check the log for details. >> "%log_file%"
)

REM Wait for user input before closing
echo Press any key to continue...
pause > nul

How to Set Up for Context Menu

1. Save the Script: Save this updated script as convert_svg_to_png.bat in a known location.

2. Add a Context Menu Entry:

   • Press Win + R, type regedit, and press Enter to open the Registry Editor.

   • Navigate to HKEY_CLASSES_ROOT\*\shell.

   • Right-click on shell, then select New > Key, and name it Convert SVG to PNG.

   • Right-click on the new Convert SVG to PNG key, select New > Key, and name this one command.

   • Double-click on the (Default) value under the command key and set its value to the path of your batch script. Wrap the path in quotes and add %1 like this:

     "C:\path\to\convert_svg_to_jpg.bat" "%1"

I haven't figured how to have it process multiple selected svg's at one time, if anyone has a clue.

theoryshaw

got it to work with multiple svgs as once, but you have to drag and drop the svgs onto the .bat script.
see attached video.

@echo off
setlocal enabledelayedexpansion

REM Log file
set "log_file=%~dp0conversion_log.txt"
> "%log_file%" (
    echo Starting conversion...
)

REM Loop through all dropped SVG files
for %%F in (%*) do (
    REM Set input and output file paths
    set "input_file=%%~F"
    set "output_png=%%~dpF%%~nF.png"

    REM Log input and output
    echo Input file: "!input_file!" >> "%log_file%"
    echo Output PNG: "!output_png!" >> "%log_file%"

    REM Process the SVG file with Inkscape
    echo Processing "!input_file!" with DPI 150... >> "%log_file%"

    REM Use the call command to enable variable expansion correctly within the loop
    call inkscape "!input_file!" --export-type="png" --export-filename="!output_png!" --export-dpi=150 --export-background=white >> "%log_file%" 2>&1

    REM Check if PNG conversion was successful
    if exist "!output_png!" (
        echo Successfully converted to PNG: "!output_png!" >> "%log_file%"
        echo Conversion complete: "!output_png!" >> "%log_file%"
    ) else (
        echo Error occurred during PNG conversion for "!input_file!". Please check the log for details. >> "%log_file%"
    )
)

REM Wait for user input before closing
echo Press any key to continue...
pause > nul

Hello guys, I have taken @theoryshaw script and enhanced it a little bit with the help of A.I to create a basic working UI. The script works well and it's a standalone .exe file. I tried implementing svg to jpeg and tiff formats but there were many bugs with it that i could not fix. But as far as Svg to Png and Pdf are concerned, it works well. There are a few iterations, the other interations you might see in the repo are python script and might require running it as these in the in the terminal
python svg_to_png_gui_G.py
python svg_to_png_gui.py-C-v2.py
python svg_to_png_gui_D-v2-NewTheme.py
python svg_to_png_gui_G-v2-NewTheme.py
python svg_to_png_gui_G-v3-NewTheme.py
python svg_to_png_gui_G-v4-NewTheme.py
python svg_to_png_gui_G-v5-NewTheme.py
python svg_to_png_gui_G-v6-NewTheme.py
python svg_to_png_gui_G-v7-NewTheme.py

But the main script here
https://hub.openingdesign.com/OpeningDesign/Utility_Apps/src/branch/main/Svg2PngPdf/dist/SVGtoPNGConverter.exe
Here are a few screenshots. The other version do have other themes attempts to it, i even tried to implement a theme that looked more like bonsai, but that was beyond me with the amount of bugs and troubleshoot and the output result wasn't so great.
