PNG to PDF Converter — Free, No Sign-Up
Select PNG images
Your files stay on your device. Nothing is uploaded.
This free PNG to PDF converter turns one or more PNG images into a single, neat PDF file in seconds — no sign-up, no software to install, and no watermark. PNG is the format of screenshots, scanned documents, design exports, logos and diagrams, and it is also the format many phones and chat apps produce when they save a picture. When a teacher, office or application portal asks you to "submit it as one PDF", this tool places each PNG on its own page, in your order, and hands you one tidy document.
PNG files are embedded into the PDF losslessly, so text in screenshots and fine lines in diagrams stay exactly as sharp as the original — nothing is re-compressed into a blurry JPEG. Everything happens locally in your browser: your images are never uploaded to a server, so private screenshots, ID documents and personal scans stay on your own device. The Fit to image option makes each page match its picture, while the A4 option centres each image on a standard paper page, ready for printing and official forms.
How to use
- Click the file box and select one or more PNG images from your device (JPG and WebP are accepted too).
- Check the list that appears and confirm the images are in the order you want.
- Choose a page size: Fit to image for screenshots, or A4 for printing and official use.
- Click Convert to PDF and wait a moment while the file is built in your browser.
- Save the downloaded file, named png-to-pdf.pdf, and open it to check every page.
Frequently asked questions
Are my PNG images uploaded anywhere?
No. The conversion runs entirely on your device using code in this page. Your files are not sent to us or to any other server, and nothing is stored after you close the tab.
Will my PNG lose quality inside the PDF?
No. PNG images are placed into the PDF directly in their original form, so screenshots and text stay pixel-sharp. This is the main advantage of converting from PNG rather than from a photo format.
Can I mix PNG with JPG images?
Yes. You can add JPG and WebP files in the same selection and they will all end up in the same PDF, one image per page. PNG pages stay lossless; the other formats are handled as they are.
Is there a limit on how many images I can add?
There is no fixed limit in the tool, but dozens of very large PNG screenshots can make a heavy PDF and be slow on older phones. If it feels slow, convert in smaller batches and merge afterwards if needed.
