Frequently Asked Questions
Q: Is Aspose better for high-resolution images? A: Yes—Aspose.PDF.Plugin supports 300 DPI+ with sharp rendering for both text and vector graphics, suitable for professional publishing and archiving.
Q: What are the limitations? A: Licenses are required for production use. Extremely complex PDFs may require parameter tuning for optimal export. For ultra-high DPI (600+), Ghostscript can outperform, but with less .NET integration and support.
Q: How can I preview before batch export? A: Use Aspose’s per-page export with visual review of a few pages before scaling to large jobs.
Pro Tip: For buyers and tech leads, prioritize long-term support, integration simplicity, and licensing flexibility—not just output quality. Aspose excels in these areas.
