When to Use PNG to PDF vs JPG to PDF
Use PNG to PDF when your sources are PNG and you want lossless quality or transparency (graphics, screenshots, diagrams). Use JPG to PDF when your sources are JPG or you want smaller file size. For multiple image formats in one PDF, use the main Image to PDF tool.
Best Practices
Follow these guidelines for better PDFs from your PNG files.
Quality and layout tips
- PNG is lossless; the PDF reflects that quality
- Choose fit mode to match intent: fit for full image, fill for full-page cover
- Reorder and rotate before converting; use preview to verify transparency
- Set a descriptive custom filename for the PDF
Common use cases
- Design & UI: Export artboards or assets with transparency into one PDF
- Documentation: Combine diagram or screenshot PNGs for sharing
- Archives: Store related PNGs as a single searchable document
- Print-ready: Control page size and margins for crisp output
- Client delivery: One PDF attachment instead of many PNG files
How PNG to PDF conversion works
The tool loads each PNG in your browser, applies your rotation and order, scales images to the page using your fit mode, and embeds them—preserving PNG and transparency when present. You can preview the PDF locally and download; nothing is uploaded to a server.
Technical steps
- Upload & order: Add PNG files (and more later). Drag to reorder and rotate 90° per image. Order defines page sequence.
- Page & fit: Set page size, orientation, margins, and image fit (fit, fill, actual size, stretch). Set output filename.
- Embedding: Each image is processed with rotation. Images with transparency are embedded as PNG in the PDF; others may use JPEG per the tool logic. Placement follows your fit mode.
- Preview & download: The PDF is built locally and shown in an in-browser preview. Convert again with different settings or download.
- Privacy: Processing runs entirely in your browser; your PNGs stay on your device.

Frequently Asked Questions
Is PNG to PDF free?
Yes. The tool is free and runs entirely in your browser. No registration required. Your PNG files never leave your device.
Can I combine multiple PNGs into one PDF?
Yes. Upload multiple PNG images, drag to reorder, optionally rotate any image, set your options, and convert. Each image becomes one page. You can add more PNGs without clearing the list.
Is transparency preserved when converting PNG to PDF?
Yes. PNG images with transparency are embedded as PNG in the PDF, so transparency is preserved. Use the in-browser preview to verify.
Can I reorder and rotate PNG images before converting?
Yes. Drag thumbnails to change page order and use the rotate button on each image for 90° clockwise. Order and rotation are applied when you click Convert to PDF.
Why use PNG to PDF instead of JPG to PDF?
Use PNG to PDF when your source files are PNG and you want lossless quality or transparency (e.g. graphics, screenshots, diagrams). Use JPG to PDF when your sources are JPG or you want smaller file size.
Is my PNG data secure?
Yes. All conversion runs in your browser. Your PNG files are never uploaded to any server. No data is stored or transmitted.
Can I set a custom filename for the PDF?
Yes. In PDF settings, set the Output filename (e.g. report.pdf). The .pdf extension is added automatically if you omit it.
How many PNGs can I convert at once?
You can add many PNG images. Limits depend on browser memory and file sizes. PNG files can be larger than JPG; you can add more images after the first batch without clearing.
