Converting PNG to PDF — What You Should Know
PNG is lossless, and it stays lossless through this conversion — the image is embedded without re-compression, so text and sharp-edged graphics in screenshots stay crisp rather than picking up the fuzzy halos that JPEG compression would add. The one thing to know is transparency. PNG supports an alpha channel, PDF pages do not render transparency the same way, and so transparent areas are composited onto the page rather than staying see-through. If your PNG has a transparent background, expect it to appear black or white in the PDF; flatten it onto the background colour you want before converting.

PNG to PDF — Frequently Asked Questions
What happens to PNG transparency in the PDF?▼
Transparent areas get composited onto the page instead of remaining transparent, so they typically appear black or white. If the background matters, flatten the PNG onto your intended colour before converting.
Is PNG to PDF lossless?▼
Yes. The PNG is embedded without re-compression, so screenshots, diagrams and text-heavy graphics keep their sharp edges with no JPEG-style artefacts introduced.
Why is my PNG-based PDF so large?▼
PNG is lossless, which means it stores far more data than an equivalent JPG. A PDF built from PNGs is correspondingly bigger. Use JPG sources instead if file size matters more than perfect sharpness.
