Batch convert images with inkscape on windows

Batch convert svg|pdf|eps|emf|wmf|ai|ps|cdr to eps|pdf|png|jpg|tiff|svg|ps|emf|wmf

Batch converter for Windows using Inkscape with the command line
InkscapeBatchConvert is an easy to use solution to quickly convert all files of a folder to another type without the need to open Inkscape. The program uses Windows Batch scripting and will only work on Windows.
Tested with Inkscape 1.0.x - 1.3.x ✅ (The last version that supports Inkscape 0.9.x can be found here)

Usage

1. Download _InkscapeBatchConvert.bat
2. Put it in the folder where you have files you wish to convert (will also scan on all subfolders for files of input type).
3. Then double click the file to start it.

Troubleshooting

Problem	Solution
Windows blocks the program	Right click the file → Properties → Unblock
I can't convert EPS / PDF files. The program says it runs the conversion, but there are no files in the out folder.	Make sure you have ghost script installed and added to your environment path. For more information read the Inkscape FAQ
Can't find Inkscape installation	All common file paths are checked for the installation. If you haven't installed Inkscape download it here, otherwise you can also define your own path in the script by adding the next array element of inkscapePaths to the script
I'm missing a setting in the script, e.g. defined output width	Have a look at the Commandline Documentation or read the inkscape help file inkscape --help and add the needed properties to the script
I'm missing a specific input or output type	If inkscape supports those types, you can easily add them to the list in the script (search for validInput and validOutput)
The files are saved to out\, but I would like to have it saved in the same directory or a subdirectory with a different name	Just change the variable relativeOutputFolder - If you want to save the files to the same directory, set it to nothing (set relativeOutputFolder=)

Todo

Use shell or pipe to avoid starting inkscape for every file as pointed out by @vaifrax here. I would be very happy to get help for that 🙂

@MaydayGD Hahaha, wow! I was already wondering what was going on with your text. Haven't heard of that problem so far, but I also have no idea on how to fix this 😄
Glad the other issues are resolved for you!

Hi, Thank you for this tool :)
In some files, My png output file is cut in half

@mysticJawel Tool exports what is on the artboard. So if your maze is not on the artboard it will export what you see. Where did you get mazes from? When you open SVG file in Inkscape are mazes on the page or over the page.

Hi @JohannesDeml,

Firstly, thank you for your batch script. After following the details of @MaydayGD (thank you too!), I managed to run the batch script, was asked the 3 questions, but it always says 0 files are saved. Any further advice would be much appreciated!

I changed the file "kind" to SVG, but still the same result.
I also tried renaming the OUT folder to "out". No effect either.

@shaye24 I tested it with the same version you used, and for me it does not have any problems.

My idea would be: Maybe there is a problem with the path, could you try to just run this under C:\Test\ or something similar (so you won't have too long paths and no special characters such as spaces).

Hi @JohannesDeml,

Thank you for your suggestion to simplify the path, I tried that and it still doesn't work. I will keep trying!

Hi @shaye24 ,

Ah I see, maybe there is a difference when running the script in Parallels? I updated the version a bit to output the actual folder where it is searching for files

Maybe that helps you debugging the problem?

Hi @JohannesDeml,

Thank you once again for trying to help, still 0 files with the folder change. I think I might have to ask a friend to try it on a proper PC!

Hi @JohannesDeml,

Just to update that I enlisted some help and my friend didn't have any problems running your batch file on his PC, thanks once again!!

How could I modify the script so that Inkscape will use the Poppler/Cairo Import instead of embedding fonts?

@machen1929 from the documentation, I would suggest having a look at --pdf-poppler, see https://wiki.inkscape.org/wiki/index.php/Using_the_Command_Line#New_options

Add this to line 147 like so %inkscapePath% --export-filename="%%~di%%~piout\%%~ni.%outputType%" --pdf-poppler --export-dpi=%dpi% "%%i"

However this is just a guess, I haven't done it so far. let us know if it works / what you found working :)

Thanks for the wonderful tool! However, it would've been great if it allowed for setting the dimensions of the png files. I have multiple svg files with different sizes and I want for the output images to have the same height (512px) since they are icons (dpi doesn't do the trick). Is there a way to implement this feature?
Also, would it be possible to add a suffix to the output files' title?

Thanks again!

What you are asking is user specific script. Everyone will have different needs. I have scripts for everything you mentioned. Resizer per width height and with distortion or not. Renamer as well. You can research that on internet.

Thanks again!

@idma-omar As @MaydayGD mentioned, you should be able to do those steps with another script/program. Maybe FastStone Photo Resizer meets your needs. Then you would export everything with a high enough resolution to png and then use this tool to rename / bring them all to the same height. I think for this script it is better to keep it simple to meet the needs of most while not making it too complicated to use/change.

I didn't get it working. Any suggestions?

@knightknight

Try this: Create a folder on the desktop, name the folder A, just the letter A, and put this SVG inside that folder: https://upload.wikimedia.org/wikipedia/commons/f/fa/ABB_world_map.svg

The put the script there and run the script and let us know what happened.

From the looks of it those files do not appear to be SVG files.

Maybe someone just changed their extension. Why is the file size of all your SVG files 1KB?

@MaydayGD, ok I have tried in C:\A and on the desktop as A. Both gave the same output as my previous post.

Found 0 file(s) of type *.svg in the current folder (C:\A\)

Fyi, I'm running this on Windows 11. As for the .svg files those where from IonIcon Designers Pack.

@knightknight I think you are missing the inkscape.exe to your path:

set inkscapePath5="C:\Users\<name>\scoop\apps\inkscape\current\bin\inkscape.exe"

Then I get the following:

@JohannesDeml, adding .exe might have worked. Except what did work was just double clicking the .bat file instead of 'Run as administrator'. Which I thought would be needed. However the out folder was empty and is being created as 'Read Only'.

Found 1 file(s) of type *.svg in the current folder (C:\Users\<name>\Desktop\A\)

The first part of the script that prints the Inkscape version still didn't work.

'--version' is not recognized as an internal or external command,
operable program or batch file.

@knightknight I'm quite sure inkscape is not found correctly in your case. I updated the script to also include the path for scoop as a possible location. Please download again and run it by double clicking (running through the terminal or command prompt should be possible as well).

@JohannesDeml, perfecto worked!!

Something must have gone wrong when I copied & pasted the RAW code first time around.

It detected the Inkscape version Running with Inkscape 1.2.1 (9c6d41e410, 2022-07-14) from "C:\Users\<name>\scoop\apps\inkscape\current\bin\inkscape.exe" and I'm getting the output folder with converted .png files.

👍

@knightknight Coolcool, glad it works now for you as well. Thanks for letting us know 🎉

Many thanks for this batch-file. It works perfectly in Windows 11.

I am producing multiple .svg files using a Python program and this library: https://github.com/RobG73/InkscapeFileMaker. Using a program to make the inkscape files means that I can make small changes to every file by changing the program. The problem is that I need to export/convert every svg file to .png before I can include them in a LibreOffice document.

Your program enables me to do this with one click. Brilliant! Thank you.

Hi @RobG73 ,

thanks for you comment, glad to hear that the script helps you in your workflow 🥳

Hello. I just tried the batch file. Unfortunately, after converting an emf file to a png file, it removes the text contained in it for me. What can I do?
This is the png-file after convert:

This ist the emf-file before convert:

Hi @wethlo448 ,

I tried reproducing the problem by creating an emf through Inkscape. I tried with both convert text to paths enabled and disabled, and in both cases the generated png included the text correctly.

Did you try to export the file file inkscape directly? And did this work? Did you also make sure to have the specific font installed? And are you using the latest inkscape version (1.2.2)?
If the answer to all of those is yes, please share a file, then I can try to reproduce it :)

Hi -thanks for this script - is it possible to convert a PDF file that has multiple pages? So far I can only get it to produce the first page.
