PNG is the format of screenshots, diagrams, charts, logos and anything with crisp text. When you need to hand those images to someone as a document (a set of screenshots for a bug report, slides exported as images, a scanned form saved as PNG), a PDF keeps them together, in order, in one file that opens everywhere. This converter places every PNG on its own page without recompressing it, so text and lines stay razor sharp.
Lossless from PNG to PDF
Many converters quietly turn PNGs into JPGs before building the PDF. That makes the file smaller but adds blurry halos around text and thin lines. Here, PNG images are stored losslessly, exactly as you uploaded them, so a screenshot of a spreadsheet or a code editor stays readable at any zoom level.
Transparent areas are kept. PDF viewers show them against the white page, so a logo with a transparent background looks clean.
Each page is sized to its image. A tall phone screenshot becomes a tall page, a wide desktop screenshot a wide page, so nothing is cropped or squashed.
Keeping the file size reasonable
Lossless means larger. Full-screen screenshots are usually 0.5 to 3 MB each, and the PDF is roughly the total of the images. If you need a smaller file for email or an upload form, run the finished PDF through Compress PDF, or shrink the PNGs first with the Image Compressor.
Combining photos rather than screenshots? JPG to PDF is the better fit for camera pictures, and Image to PDF accepts a mix of PNG, JPG, HEIC and WebP in one file.

Frequently asked questions
How do I convert PNG to PDF for free?
Add your PNG files on this page and press Convert. You get one PDF with one page per image. No sign-up, no watermark.
Will my PNG lose quality in the PDF?
No. PNG images are embedded losslessly, so text, lines and colours stay exactly as they were.
Is transparency kept?
Yes. Transparent areas stay transparent and show as white in normal PDF viewers.
Can I combine several PNGs into one PDF?
Yes. Add as many as you need; they appear as pages in the order you added them.
Why is my PDF large?
PNG is lossless, so the PDF keeps every pixel. Use Compress PDF afterwards if you need a smaller file.
