Aspose.Words save to PDF Full Font Embedding

Does Aspose.Words support full font embedding when saving a Word document to PDF? It seems I can only get it to save a subset of the font. If it is possible, can you supply a code sample as to how this is done?
Thanks in advance.


Thanks for your request. Why do you need to embed full font into PDF file? This can make the output PDF document to be unacceptably huge. For instance, if you use one character of ArialUni font, whole font will be embedded into the output PDF file. ArialUni font weights 22MB, so PDF with only one character inside will also weights at least 22 MB. What will be if you use several fonts in your document?
So to decrease the output PDF size Aspose.Words subsets the original fonts.
Best regards.

Hi Alexey,
I vote for this request too. A user must decide how to embed the each font:

  1. No embedding
  2. Used subset embedding (default option)
  3. Full font embedding

Option 3) is very important to provide editing of the document later. About sizes: the most of widespread fonts have size in a range 10-100Kb but in case of huge font a user can choose another option.

Hi Evgeniy,

Thank you for additional information. I logged this as new feature request. We will consider adding such option in one of future versions. You will be notified as soon as it is available.
Best regards.

Thanks Alexey for the background on why Aspose.Words subsets the fonts. It makes complete sense to me. Unfortunately we have an integration with a vendor of ours that needs the full font embedded. So if this could be added as an option that is configurable that would be fantastic.
As a side note, we have been using Aspose.Words for about 1 month and it is fantastic product. Thank you for putting it out there.


My name is Alexander I work on implementation of full font embedding feature. I have encountered a little problem - I am not sure how could I test my code. Adobe products do not use embedded font for later editing and as far as I know do not suporrt it. Could you please check the attached PDF documents and verify which of them (if any) suites to your needs? Or probably you could provide me a link to software (for Windows) that you use and describe a test case in order to test the feature implementation on my side?

Hello Alexander,
Unfortunately I do not see any attachments. Can you try to provide those again? I should be able to verify if they are what I am looking for.
I do not know of any software that implements this feature at this time. I don’t own any of the Adobe products to test this out myself.
Thank you for your assistance.

Hello Errol,

I send the attachment to your e-mail.
Best regards,

I just received them. They all look like they have subset fonts. I appreciate your continued effort on this feature.
Best Regards,

Hi Errol,

Please find in attach one more document. Adobe Acrobate defines the fonts in it as Embedded in opposite to Embedded Subset in previous version so I suppose it should work you. Please let me know if it does. In case if you can’t see the attachment please contact me via alexander.novickov (at) aspose (dot) com

Hi Alex,
I think you got it. That looks like the fonts are fully embedded.
Thank you!
Best Regards,

Hi there,

I am just evaluating Aspose.Words and encountering problems if fonts are embedded in the source files (word documents).

With which parts of the API can I control the font embedding options of Aspose.words?

Kind regards,


Thanks for your request. What you are asking for is using fonts embedded into the Word documents upon rendering. I am right? Unfortunately, this feature is not yet supported. Currently, Aspose.Words requires that fonts used in the document were installed on PC where you perform conversion. I linked your request to the appropriate issue. You will be notified as soon as fonts embedded into MS Word documents are supported upon rendering.
Best regards,

A fix for the issue(s) you’ve reported (filed as 7626) will be released in the next release at the end of this month. You will be notified.
