I have one .vsdx file which is of around 23 MB.
trying to attach file but it is failing
I am getting OOM error while converting it.
We are using aspose.diagram version 29.3 and java 11
I have set -Xmx to 15GB but still OOM.
Thanks for the report. I have not confirmed this yet and can only confirm it after reproducing on our side. Based on your description, this might be a bug in Aspose.Vsdx when converting vsdx to unknown. To confirm and log it internally, I need a few details.
- Which format are you converting the .vsdx to (e.g., PDF, PNG, SVG, etc.)?
- Could you share the code snippet you use to load and convert the diagram, including any load or save options?
- What is the operating system and JVM architecture (32‑bit vs 64‑bit) you are running?
A support engineer will review your details and get back to you.
Once I have the missing details, I’ll try to reproduce this. If I can confirm it, I’ll log it internally and follow up here.
A support engineer will follow up in this thread if needed.
I am converting .vsdx to PDF.
Here is the code snippet
protected File convertToTempPdf(File inputFile, File converted) throws Exception {
try {
String sourcePath = inputFile.getAbsolutePath();
InputStream stream = new FileInputStream(sourcePath);
// load diagram
Diagram diagram = new Diagram(stream);
diagram.save(converted.getAbsolutePath(), SaveFileFormat.PDF);
stream.close();
return converted;
} catch (Exception e) {
throw new Exception(e);
}
}
We are using Windows 11 and JVM is OpenJDK 64-Bit Server VM Zulu11.78+15-CA
Thanks for the sample file(s); that should help with reproduction. I have not confirmed this yet and can only confirm it after reproducing on our side. Based on your description, this might be a bug in Aspose.Vsdx when converting vsdx to pdf. To confirm and log it internally, I need a few details.
- Could you paste the full Out‑Of‑Memory exception stack trace you receive?
- Are you using any
LoadOptionsorSaveOptionswhen loading the diagram or saving to PDF? - Have you verified that the JVM is actually starting with the
-Xmx15gsetting (e.g., viajcmdor a startup log)?
A support engineer will review these details and follow up in this thread.
I’ll try to reproduce this using your samples. If I can confirm it, I’ll log it internally and follow up here.

Thanks for your inqueries
Please compress the vsdx file then upload it(The maximum size is 25MB), or share it via Dropbox, or send it to me as an internal message.
We need to evaluate your issue in details.
Thanks.
I have a 22MB file but it is not allowing me to upload
Eventhough the allowed limit is of 200MB
How can I send it as internal message?
Here is the dropbox link for the file
https://www.dropbox.com/scl/fi/4e8kv7zkdxe4ajp0ui3cy/original_7.vsdx?rlkey=p6qz13qeb5w0a9bo8j3wyqu3m&st=321gz1bq&dl=0
Thanks for the template file.
After an initial testing, I am able to reproduce the issue as you mentioned by using your template file.
