A PNG to PDF converter that keeps every pixel
Lossless, sharp pages
PNG pixels are stored in the PDF without lossy compression, so screenshots, diagrams and text in images stay crisp, and transparent areas show as clean white paper.
Full page control
See every image as a page, drag to reorder, rotate one page or all of them, duplicate, delete, insert blank pages, sort by name and undo any step with Ctrl+Z.
Fit, A4 or Letter pages
Keep each page the shape of its image, or place every image on an A4 or Letter page with no, small or large margin. Wide images get a landscape page automatically.
Checks your files first
Images with a wrong extension or no file type are recognised by their content, incomplete PNGs are repaired where the browser can read them, and empty files are skipped with a clear note.
How to convert PNG to PDF online
PNG is the format of screenshots, scanned forms saved from apps, charts, diagrams and logos. It is perfect on screen, but a PDF is easier to send, print, sign and archive, and it keeps several images together in the right order. BestConverter converts PNG to PDF directly in your browser, so the images never leave your device and the PDF is ready in seconds.
Put the pages in order
After you choose your files, each PNG appears as a page in a full-screen workspace. Files are sorted by name the way people expect, so scan-2.png comes before scan-10.png. Drag pages to change the order, rotate a sideways screenshot, duplicate a page you need twice or remove one you picked by mistake. You can add more PNG, JPG or other images, and even existing PDF files, at any position, and the preview lets you check a page at full size before you create the PDF.
Tips for the best result
- For screenshots and slides read on a screen, keep the page size on Fit to image so there are no white borders.
- For printing or official documents, choose A4 or Letter and a small margin so nothing is cut off by the printer.
- Name your files with numbers (01, 02, 03) before you upload and they will already be in order.
- Only the first frame of an animated PNG is used, because a PDF page cannot animate.
Download it your way
When the PDF is ready you can rename it and download it straight away, convert it to Word, Excel, PowerPoint, JPG or PNG in the same dialog, save it to My documents, or open it in the PDF editor to add text, sign or highlight. There is no sign-up, no email and no watermark, and the tool works on phones, tablets and computers.

Frequently asked questions
Is it safe to convert PNG to PDF online?
Yes. The images are read and turned into a PDF inside your browser on your own device. Nothing is sent to BestConverter or anyone else, which makes it safe for screenshots of private chats, bank pages or ID scans.
Does converting PNG to PDF reduce image quality?
No. The image pixels are copied into the PDF without lossy compression, at their full resolution. The page size only changes how big the image appears, not how many pixels it keeps, so you can zoom in as far as the original allows.
What happens to a transparent PNG background in the PDF?
Transparency is kept in the PDF, and like any PDF page the background behind it is white. A logo or icon on a transparent background therefore appears on a white page, both on screen and in print.
How do I combine multiple PNG files into one PDF?
Select or drop as many PNGs as you like and each one becomes a page in a single PDF. Files are sorted by name with numbers in the right order, and you can drag pages anywhere, add more images or PDFs, or insert blank pages before you create the file.
Which page size should I choose for my PDF?
Fit to image makes every page exactly the shape of its picture, ideal for screenshots and slides read on screen. Choose A4 or Letter when you will print the PDF or send it as a document; each image is centred and scaled to fit, with an optional margin.
Why is my PDF larger than my PNG files?
PNG is already compressed and the PDF stores the same pixels losslessly, so the result is usually about the size of the images combined, sometimes a little larger. If you need a smaller file for email, run the PDF through Compress PDF afterwards.
