Why Convert PNG to PDF?
PNG files are ideal for high-quality images with transparency, but they’re less practical for sharing multiple files or ensuring consistent formatting across devices. Converting to PDF offers key benefits:
- Unified Documents: Merge multiple PNGs into one PDF for reports, portfolios, or e-books.
- Professional Presentation: PDFs maintain layout and quality, unlike PNGs, which may vary by viewer.
- File Size Reduction: Compress images during conversion to save space (e.g., reduce a 15 MB PNG to a 3 MB PDF).
- Security Options: Add passwords or watermarks to protect sensitive content.
- Universal Compatibility: PDFs open reliably on any device, perfect for emailing or archiving.
With over 350 million monthly users relying on online converters, these tools use 256-bit SSL encryption and delete files after processing (typically 1–2 hours) to ensure privacy.
