About PNG to PDF
PNG is lossless, which makes this conversion different from its JPEG counterpart in one respect that matters: there is no generational quality loss to worry about, and screenshots and diagrams with sharp edges and flat colour stay perfectly crisp. The cost is size — a PNG of a detailed screenshot is often several times larger than the JPEG equivalent, and that carries into the PDF. Each image becomes one page, scaled to fit while preserving its aspect ratio.
When to use PNG to PDF
Turning screenshots into a document
Bug reports, step-by-step guides and audit evidence are usually PNG screenshots that need to arrive as one file, in order.
Combining diagrams and charts
Exported diagrams keep their crisp lines and flat colour through a lossless conversion, where JPEG would add halos around every edge.
Submitting images where only PDF is accepted
Many portals accept a single PDF and nothing else, regardless of what you actually have.
Limitations worth knowing
- PNG transparency has no equivalent in a PDF page, so transparent areas are composited onto white.
- One image per page; multiple images on a single page is not supported.
- PNG files are large, and the resulting PDF inherits that. Run the compressor afterwards if size matters.
- No OCR is performed — text inside a screenshot stays an image and is not searchable.

Frequently asked questions
Should I use PNG or JPG images for my PDF?+
It depends entirely on the content. Screenshots, diagrams, logos and anything containing text belong as PNG — lossless, so edges stay sharp. Photographs belong as JPEG, which compresses them far more efficiently with no visible difference. Using JPEG for screenshots produces visible halos around text.
What happens to transparent areas?+
They are composited onto a white background. A PDF page has no alpha channel, so transparency must resolve to something — this is worth knowing if your PNG has a transparent background that was hiding an awkward edge.
My PDF is very large. Why?+
Because PNG is lossless and lossless is big, particularly for detailed screenshots. The conversion embeds the image data as-is rather than re-compressing it, so the PDF is roughly the sum of your PNGs. Run it through the PDF compressor if you need it smaller.
