PNG to PDF converter
Drop PNG images or screenshots below and download a PDF with one page per image, or one PDF per file. The pixels are copied losslessly, so text in screenshots stays sharp, and nothing is uploaded.
How to convert PNG to PDF
- Add your images. Drag PNG files onto the box above, or tap Choose files. Screenshots pasted from the clipboard work too.
- Pick the page. Same as the image makes each page the size of its PNG. A4 or US Letter fits it on a standard sheet with a margin.
- Download. Each row gives a PDF of that image; Download all in one PDF puts them all in one file, in the order of the list.
Files in another format are listed with a short reason and a link to the right converter, and the rest of the batch carries on.
What this converter does with your PNG
PNG is lossless, and so is the PDF this page makes: the pixels are copied into the PDF with the same lossless compression PDF uses for images (Flate, the method behind zip files), never re-encoded as JPEG. Text, lines and flat colors in screenshots stay exactly as sharp as in the PNG. Transparent areas are placed on white, since a PDF page is white.
Why convert PNG to PDF?
Screenshots are the usual reason. A chat conversation, a bank confirmation, an error message, a boarding pass or an online receipt is a PNG on your phone, and the person or portal asking for it wants a PDF, often a single one. A PDF also keeps several screenshots together in order, prints on a standard page and opens anywhere without a photo app.
The iPhone screenshot guide shows where iOS keeps them; this page turns them into the document.
What the PDF keeps, and what it leaves out
- Kept: every pixel at the original resolution, exactly.
- Left out: transparency, which becomes white, and any text chunks or metadata stored in the PNG.
- Size: a lossless PDF of a photo saved as PNG can be large, since lossless compression cannot shrink photos much. For photos, convert to JPG first or use the JPG to PDF converter.

Your images stay on your device
The PDF is written by your browser, from files read on your disk, and saved to your downloads folder. No server ever receives your files, and nothing is kept once you close the page. It is the same promise we make in our iPhone app, PrunePic: it reviews your photos on the iPhone itself and never uploads them.
Screenshots piling up?
Once the PDF is sent, the screenshots usually stay on the phone forever. PrunePic shows them one at a time, and you swipe left to delete or up to keep; the guide to deleting all screenshots covers the Photos app way too.

Frequently asked questions
Is the PNG to PDF converter free?
Yes, free with no sign-up, no watermark and no limit on the number of images. It runs in your browser.
Does converting PNG to PDF reduce quality?
No. The pixels are stored losslessly in the PDF, so screenshots and graphics come out exactly as sharp as the PNG.
Can I combine several PNG files into one PDF?
Yes. Add the files in the order you want and tap Download all in one PDF. Each row also gives a single-page PDF of its image.
What happens to transparent areas?
They become white, as a PDF page is white. The PNG itself is not changed.
Why is the PDF bigger than I expected?
Lossless compression keeps every pixel, which is large for photos. For photographs, convert them to JPG first, or use the JPG to PDF converter, which stores them compactly.
