How to Convert PNG to PDF
- Add your PNG images by dragging them into the box above, clicking Choose PNG Files or pasting a screenshot.
- Arrange the pages. Each image becomes one page. Use the ▲ ▼ arrows to change the order.
- Choose single or separate PDFs. Keep Combine into one PDF on for a multi-page document, or switch it off to get one PDF per image.
- Convert, preview and download. The finished PDF opens in a preview window so you can check every page first.
Why Convert PNG to PDF?
PNG is great for screenshots, scanned notes and graphics, but many places only accept PDF: job portals, government forms, school assignments and print shops. A PDF also keeps several images together in one file, so you can send a whole set of receipts, sketches or slides as a single attachment instead of ten separate pictures.
Combine Multiple PNG Files Into One PDF
Add as many PNG images as you need. K4Converter places each one on its own page, sized exactly to the image, so nothing is cropped, stretched or shrunk onto a fixed paper size. This is ideal for turning a batch of screenshots into a tidy report or merging phone scans of a document into one file.
Tip: Name your files in order (01.png, 02.png…) before adding them, or simply reorder them with the arrows after adding.
What Happens to Transparent Backgrounds?
PDF pages created from images don't keep PNG transparency, so transparent areas are filled with white by default. Want a different look? Pick any color with the Background option before converting.
Private, Fast and Free
- No upload: the PDF is built inside your browser, so your images never leave your device.
- Unlimited pages: no daily limits, no watermarks and no signup.
- Adjustable quality: lower the quality slider for a smaller PDF that's easier to email.
- Works everywhere: Windows, Mac, Chromebook, iPhone and Android.
Need other formats too? Our PNG Converter also turns PNG into JPG and WebP, and you can combine JPG photos into a PDF the same way.
Works on Every Device
The PNG to PDF Converter runs in any modern browser: Chrome, Safari, Edge and Firefox on Windows, Mac, Chromebook, iPhone, iPad and Android. Because everything happens on your device, it's fast even on slow connections and keeps working if your internet drops after the page loads. There are no file-size caps set by a server, and no account, email address or watermark is required.
Troubleshooting & Tips
- The PDF is too large to email Lower the quality slider to 70–80% and convert again. Screenshots and text pages still stay readable.
- Pages are in the wrong order Use the ▲ ▼ arrows beside each file before converting. Page 1 is at the top of the list.
- I need one PDF per image Switch off "Combine into one PDF". Each PNG becomes its own PDF, and you can download them together as a ZIP.
- My logo has a white box around it PDF pages from images can't be transparent. Choose a background color that matches where you'll use the document.
