Why Convert PNG to PDF?
Document Submission
Many institutions require PDF format for uploaded documents. Convert your PNG screenshots and scans to PDF for forms, applications, and reports.
Combine Multiple Images
Merge multiple PNG screenshots or graphics into a single, organized PDF document. Much easier to share than a folder of separate files.
Preserve Transparency
PNG supports transparent backgrounds. When converted to PDF, transparency is preserved, making it ideal for logos and design assets.
Print-Ready Output
PDF maintains exact dimensions and resolution for consistent printing. Convert your PNG designs to PDF for professional print output.

Privacy: Why Client-Side Processing Matters
When you use a cloud-based PNG to PDF converter, your images are uploaded to a remote server, processed, and then downloaded back. During that time, your files — which may contain screenshots of sensitive data, medical images, or confidential designs — exist on a third-party server.
MiOffice uses a fundamentally different approach. The entire conversion happens in your browser using WebAssembly. Your PNG files are loaded into browser memory, converted to PDF locally, and the result is saved directly to your device. No network requests are made with your file data — ever.
