PDF file size is quite large

GemBox.Document
1

I also noticed the PDF files that GemBox generates are quite large, when compared to other PDF libraries. Is there some way to reduce file size? Thanks

Examples:

image257×333 2.77 KB

Usually 2-4 times larger than what Aspose produces

Hi James,

Try using this:

var document = DocumentModel.Load("input.docx");

var pdfSaveOptions = new PdfSaveOptions();
pdfSaveOptions.ImageDpi = 220;

document.Save("output.pdf", pdfSaveOptions);

Does this solve your issue?

Regards,
Mario

Hi James,

Currently, GemBox.Document provides optimizations primarily for images embedded in PDF files. It doesn’t provide other aspects, such as content stream compression and removal of redundant operations.

But we have an internal support ticket for a PDF compression feature and I have added your report to it to increase its priority.

At this moment, I cannot tell you exactly when it will be implemented. Please note that we prioritize feature request implementations by the number of users requesting them and currently we are working on some other features that have greater priority (more user requests).

Regards,
Mario

No worries, thanks for explaining. This isn’t really a deal-breaking issue for us, my other thread with the formatting issues are much higher. :slight_smile:
