Free converter
PNG to PDF
Place PNG images onto A4 PDF pages, scaled to fit and centred. Useful for turning screenshots and scans into a shareable document. Because the conversion runs in your browser rather than on a server, your file is never uploaded, never stored and never seen by anyone else.
Drop your file to start.
The converter needs JavaScript, because the conversion itself runs on your own device rather than on a server. Enable JavaScript to load it.
Transparency becomes a solid background
PDF pages are opaque, so any transparent areas in the PNG are filled with the background colour set in Settings, white by default. Choose a different colour there if it suits the document better.
Good for screenshots
Screenshots are usually PNG, and PDF is usually what forms and support portals ask for. This converts one to the other without your screenshot leaving the device, which matters when it shows account details or private correspondence.

Frequently asked questions
What happens to transparency?
It is filled with the background colour chosen in Settings, since PDF pages cannot be transparent.
Can I merge several PNGs into one PDF?
No. Each image produces its own single-page PDF. Merging requires server-side PDF tooling, which is outside what a browser can do reliably.
Will the image be resized?
It is scaled to fit inside the A4 margins while keeping its aspect ratio. Nothing is cropped or stretched.
Is it really free?
Yes. No account, no limits and no watermark.
