PNG to PDF Converter – Merge PNGs into One PDF

Turn PNG images and screenshots into one tidy PDF. Reorder pages, pick a paper size — free, and your files stay on your device.

How to convert PNG to PDF

1. Drop your PNG files or screenshots into the box above, or tap Choose photos. JPG and HEIC can be mixed in.
2. Put the pages in order with ↑ and ↓.
3. Pick a page size and tap Create PDF.

Merging many screenshots into one PDF

Most people who combine PNG files are collecting screenshots: a chat history, a series of payment confirmations, steps of a bug report, or pages of an online course. A few tips keep the result easy to read:

• Add files in the order they were taken. Screenshot names usually contain the date and time, so selecting them all at once from a folder sorted by name normally keeps them in order. Fix any strays with the ↑ and ↓ buttons.
• Choose “Fit to photo” for reading on screen. Each page takes the exact shape of the screenshot, with no white border, so a phone screenshot becomes a tall narrow page that scrolls naturally.
• Choose A4 or Letter for printing or official submissions. Each screenshot is centred on a standard page with a small margin, so nothing is cut off by the printer.
• Remove duplicates before you create the PDF. It is easy to take the same screenshot twice; tap Preview to check and × to drop one.

Great for screenshots

Screenshots of chats, receipts, booking confirmations or web pages are usually PNG files. Combining them into one PDF makes them easy to share, print or attach as evidence. If you already have a PDF and want these pages added to it, create a PDF from the screenshots here and join the two with Merge PDF.

Transparent areas in a PNG are placed on a white background, so they look the same in every PDF reader.

Keeping the PDF small

PNG files can be large. Inside the PDF each image is stored as a high-quality JPG of up to 2400 pixels, which usually makes the PDF much smaller than the original PNGs while staying sharp. For a strict upload limit, shrink the images first with Compress Image and add the results here.

Very long scrolling screenshots

Some phones can capture a whole chat or web page as one “scrolling” screenshot, which may be several thousand pixels tall. To keep PDFs a manageable size, every image is limited to 2400 pixels on its longest side. A normal phone screenshot (around 2500 pixels tall) barely changes, but a screenshot 8000 pixels tall is scaled to under a third of its size — and small text becomes hard to read.

If your screenshot is much taller than it is wide, crop it into a few parts of up to about 2400 pixels each before adding them here. Each part then keeps its full width and every line stays sharp, and the parts appear one after another in the PDF.

PNG vs. the PDF version

For screenshots with flat colours and text, quality 88 keeps edges clean; you would have to zoom in a long way to spot any difference. If you need the original PNG pixels untouched, keep the PNG files alongside the PDF. Should you only have the PDF later, PDF to PNG turns its pages back into images, although they will be the slightly compressed versions stored in the PDF.
