PNG to PDF
Put screenshots, scanned pages and diagrams into one PDF that is easy to send, print or attach to a form. PNGs go in lossless, so text stays crisp, and everything happens on your own device.

Screenshots and scans in one file
A folder of screenshots is awkward to share: the order gets lost, some apps resize them, and forms often accept a single PDF only. Putting them into one PDF fixes all three. The order you set here is the page order, and every page keeps the exact pixels of its PNG.
Lossless all the way
PNG is a lossless format, and it stays that way in the PDF. That matters for screenshots of text, receipts, diagrams and scanned documents, where a lossy format would blur the edges of letters. The flip side is size: a PDF of PNGs is about as large as the PNGs themselves.
Page size
With Fit to image, each page is the size of its screenshot, which reads well on screen and keeps phone screenshots tall and narrow. If the PDF is going to a printer or into an application form, choose A4 or Letter: each image is scaled to fit and centred, wide images get landscape pages, and the small margin keeps everything clear of the printer’s edge.
How it works
Your browser reads each PNG and places it in a new PDF using pdf-lib, inside a background worker. Nothing is uploaded, and the finished PDF goes straight to your downloads. Need to add it to other documents afterwards? Merge PDF files joins several PDFs into one. If the images are photos and the PDF comes out too large, convert them with PNG to JPG first, or shrink the finished file with Compress PDF.
Frequently asked questions
Will text in my screenshots stay sharp?
Yes. PNG images are stored in the PDF without any lossy compression, so every pixel is kept and small text looks exactly as it does in the original screenshot.
What happens to transparent areas?
Transparency is kept. A PDF reader shows the page colour, normally white, through the transparent parts, the same way your image viewer shows a checkerboard or a background.
Why is my PDF about as big as my PNGs?
Because nothing is thrown away. If you need a smaller file and the images are photos rather than screenshots, convert them to JPG first with the PNG to JPG converter, or run the finished PDF through Compress PDF.
Is anything uploaded?
No. The PDF is built in your browser with the open-source pdf-lib library, and your files never leave your device.
