ArchitectureWASM Pipeline
How the Conversion Pipeline Works
The conversion executes in two discrete steps inside this browser tab: first, the PNG source is decoded into uncompressed raw pixels in memory. Second, those raw pixels are re-encoded into valid PDF format without quality degradation.

PNG to PDF FAQ
How do I convert PNG to PDF?
Drop your PNG file into the tool above, then download the PDF. Everything runs in your browser - your image is never uploaded to a server.
Is converting PNG to PDF free?
Yes. There is no signup, no watermark and no limit on the number of files.
Will I lose quality converting PNG to PDF?
The page carries a quality-92 JPEG, or a lossless PNG when the source has transparency.
What is the difference between PNG and PDF?
Turn a PNG into a one-page PDF, transparency included. A single page sized to the image, ready to print or attach.
Does converting PNG to PDF need a plugin or an install?
No. PDF needs no compression library - it is assembled from the decoded pixels by a small built-in writer built on pdf-lib.
Is transparency kept in the PDF?
No. PDF has no alpha channel, so transparent areas are composited onto white before encoding.
Is EXIF and GPS data kept in the PDF?
No. Conversion goes through raw pixels, so EXIF, GPS coordinates, IPTC and XMP are all dropped. That is usually what you want before sharing a photo - but if you need to keep the format and only remove metadata, use the Metadata Remover instead.
