PNG to PDF Converter

The PNG-specific version of the image-to-PDF converter — built for the format that dominates screenshots, exported graphics, and any image that needs sharp edges or transparency, and it handles the one thing that trips up a naive PNG-to-PDF conversion: transparent backgrounds.

What happens to transparency

PDF pages have no concept of a transparent area — every pixel has to be some solid colour — so before encoding, any transparent or semi-transparent part of a PNG is filled with white. Skipping that step is exactly what produces the black backgrounds people sometimes get from other tools: without an explicit fill, transparent pixels default to black in a JPEG, which is the format used internally to embed the page.

Screenshots and text sharpness

PNG is a common export format for screenshots specifically because it is lossless, and converting to PDF here re-encodes it as JPEG, which is lossy — fine photographic detail survives that conversion well, but small, high-contrast text can visibly soften at lower quality settings. For a screenshot with a lot of small type, push the quality slider up toward 95 to keep text legible; for straightforward photographic content the default setting is usually enough.
