PNG to PDF Converter — Free & Private
You have screenshots, scans or receipts to submit and the form wants a document. Convert it here — in your browser, with nothing uploaded anywhere.
Why convert PNG to PDF?
PNG is what a screenshot tool produces and what a scanner app exports, and it is precisely the wrong thing to attach to anything official. Wrapping it in a PDF changes nothing about the picture and everything about whether the other end will accept it — a PDF opens the same way on every device, prints predictably, and does not arrive rotated.
The catch worth knowing about
PNG transparency cannot survive: a PDF page has to have a colour, so anything transparent is composited onto white. For a screenshot or a scan that is invisible, but a logo with a transparent background will pick up a white rectangle.
One tip before you start
Screenshots of text are worth keeping at high quality. The compression that is harmless on a photograph is what makes small type look furry, and the reader on the other end may be trying to make out an account number.

Will I lose quality converting PNG to PDF?
The page image inside the PDF is JPG-compressed at 92% quality, so it is lossy in the same way and to the same degree as a JPG export.
Do my PNG files get uploaded?
No. The conversion runs on your device, in the browser tab you are reading this in. You can prove it: disconnect from the internet and convert anyway.
Is it free, and how many PNG files can I do at once?
Free, with no sign-up, no watermark and no daily limit. Up to 200 files per batch, downloadable individually or as one ZIP.
