Can I convert multiple PNGs into one PDF?

Yes! Upload multiple PNG files and they'll all be combined into a single PDF document. Each PNG becomes a separate page in the order you upload them. This is perfect for creating PDFs from multiple screenshots, scanned pages, or images.

Will PNG transparency be preserved in the PDF?

Yes, PNG transparency is preserved in the PDF. However, some PDF viewers may display transparency differently—some show it as transparent, others may render it as white. The transparency data is maintained in the PDF file. For guaranteed display, test in multiple PDF viewers.

What's the maximum PNG file size I can convert?

The practical limit depends on your browser's available memory. For best performance, we recommend PNGs under 10MB each. Very large PNGs (20MB+) may process slowly or cause browser issues. For multiple large PNGs, convert them in smaller batches.

Can I control the PDF page size?

PDF page size automatically matches PNG image dimensions. If you need specific page sizes (A4, Letter), resize your PNGs to those dimensions first using our Image Resize tool, then convert to PDF. This ensures the PDF pages match your desired size.

What happens if I upload an animated PNG (APNG)?

Animated PNGs (APNG) convert only the first frame to PDF—the animation is lost. Only static PNG images are fully supported. If you need to preserve animation, use video conversion tools or keep the PNG in its original format.

What is a PNG to PDF Converter?

A PNG to PDF converter transforms image files (PNG, JPG, and other formats) into professional PDF documents. Our converter processes everything in your browser, ensuring your images and documents remain completely private.

Converting images to PDF is essential for creating professional documents from screenshots, scanned documents, receipts, or photos. PDFs maintain consistent formatting across all devices and operating systems, making them the universal standard for document sharing.

This tool is ideal for students converting handwritten notes and diagrams into submission-ready PDFs, professionals creating polished documents from screenshots and charts, photographers delivering image portfolios in PDF format, and anyone who needs to combine multiple images into a single shareable document.

Compared to using Adobe Acrobat or Microsoft Print to PDF (which requires opening each image individually), or online converters that upload your files to cloud servers, PureXio's converter is faster, more private, and supports batch conversion. You can convert multiple images at once, arrange their order, and adjust page sizing — all without leaving your browser.

The tool supports PNG, JPG, JPEG, WebP, and other common image formats. Output PDFs maintain the original image resolution and can be configured for different page sizes (A4, Letter, custom dimensions).

Best for: converting single or multiple images to PDF. Supports PNG, JPG, WebP, and more. Batch processing with custom page sizes. Fully private.

Limitations & Constraints

Very large PNG files (>20MB each) may process slowly when converting to PDF

PNG images with transparency are preserved, but some PDF viewers may display transparency differently

Multiple PNGs create multi-page PDFs—each PNG becomes one page in the order uploaded

PNG resolution determines PDF page size—high-resolution PNGs create large PDF files

Animated PNGs (APNG) convert only the first frame to PDF—animation is lost

Troubleshooting

PDF creation fails or shows error

Solution: Ensure PNG files are valid image format. Try converting PNGs one at a time, or check if files are corrupted. Verify the PNG files open correctly in an image viewer. If some PNGs fail, try converting them individually to identify problematic files. Prevention: Use standard PNG format. Avoid corrupted or unusual PNG variants.

PDF file size is very large

Solution: PNG resolution determines PDF size. High-resolution PNGs (3000×4000 pixels) create large PDFs. Consider resizing PNGs before conversion using our Image Resize tool, or use PNG compression tools first. For web use, 150-200 DPI is usually sufficient. Prevention: Resize large PNGs before conversion if file size is a concern.

Transparency lost in PDF or appears as white background

Solution: Some PDF viewers don't display transparency correctly. The transparency is preserved in the PDF, but viewers may render it as white. Try opening the PDF in different viewers (Adobe Reader, Chrome PDF viewer). For guaranteed transparency display, convert PNG to non-transparent format first, or use desktop software with transparency support. Prevention: Test PDF in multiple viewers to verify transparency rendering.

Multiple PNGs appear in wrong order in PDF

Solution: PDF pages are created in the order PNGs are uploaded. Reorder PNG files before conversion—remove all files and add them in the desired sequence. The first PNG uploaded becomes page 1, second becomes page 2, etc. Prevention: Upload PNGs in the correct order from the start.

PDF pages are wrong size or don't match PNG dimensions

Solution: PDF page size matches PNG dimensions exactly. If pages seem wrong size, the PNG itself may have unexpected dimensions. Check PNG dimensions in an image viewer. For standard page sizes (A4, Letter), resize PNGs to those dimensions first using our Image Resize tool. Prevention: Verify PNG dimensions before conversion if specific page size is required.
