How to use the PNG to PDF converter
- Add your images. PNG, JPG and WEBP files all work, and you can add many.
- Put them in order. Move images up or down until the pages are in the sequence you want, and remove any you do not need.
- Choose the page size: A4, Letter or fit. Fit makes each page match its image.
- Choose portrait or landscape, then set the margin around each image.
- Create the PDF and download it. Every image becomes one page of a single file.
The PDF is built in your browser. Your images are not uploaded, and there is no account, limit or watermark to deal with.
Why combine images into one PDF?
A PDF opens the same way on every device, keeps pages in order and is easy to attach to an email or an application form. That makes it the right container for a set of images. A folder of ten PNG screenshots is awkward to send. One PDF of ten pages is simple to read.
It also removes guesswork for the person on the other end. They do not need to know which image comes first, or which program opens a WEBP file. They open one document and scroll. If a form or portal accepts PDF but not images, this is also the quickest way to get your pictures through.
Turn phone pictures of forms, receipts or contracts into a single tidy file.
Collect screenshots in the right order for a bug report, a client update or a guide.
Combine mockups or pages into one document for review.
A set page size and margin makes printing predictable, and nothing gets cut off.
Choosing page size and orientation
| Option | What it does | Best for |
|---|---|---|
| A4 | 210 by 297 mm page | Most countries outside North America |
| Letter | 8.5 by 11 inch page | United States and Canada |
| Fit | Page matches the image | Screenshots and artwork you do not want to resize |
A4 and Letter are the standard sizes for paper. Pick the one your printer and recipient use. The image is placed on the page inside the margin, so a wide image on a tall page leaves empty space above and below.
Orientation helps here. Choose portrait for tall images such as phone screenshots and scanned pages, and landscape for wide images such as slides, charts and banners. If your set mixes both, fit is the simplest choice, because each page takes the shape of its image and nothing is shrunk to make room.
Margins and layout
A margin is the blank border between the edge of the page and the image. A small margin looks tidy on screen. A larger one is safer for printing, because many printers cannot print right to the edge of the paper. If you plan to punch holes or bind the pages, allow extra space.
For a screenshot report, a modest margin keeps the image from touching the page edge. For a poster or a photo that should fill the sheet, set the margin to zero, or use fit so the page is exactly the image.
Getting the order right
The page order is the order of your list. Before you create the PDF, scan the list and use the move controls to fix any mistakes. Remove duplicates and test shots now, because it is easier than editing the PDF afterwards. If your files are named with numbers such as page-01, page-02, add them in sequence so you start nearly sorted.
Image quality and file size
The PDF contains your pictures, so its size follows theirs. A PDF built from ten big PNG screenshots can be large. If you need a smaller file, convert the PNG images to JPG first with the PNG to JPG converter, then build the PDF from the lighter files. For text-heavy scans, check the result at normal zoom to make sure small print is still readable.
Before you send the file, open the PDF and flick through every page. Check the order, look for cropped edges and make sure nothing is sideways. That takes less than a minute and avoids an awkward reply.
Name the file clearly before you send it. If your images are different sizes, fit keeps each one at its natural shape, while A4 or Letter places every image on an identical page, which looks more uniform in print. Try both and compare. A name such as invoice-march-2026.pdf is easier to find later than a default name, and it tells the recipient what they are opening.
Privacy
Documents often hold personal details, such as IDs, invoices and medical letters. Because everything happens in your browser, the images are not sent to a server. Even so, keep sensitive files off shared computers, and close the tab when you are finished.
Frequently asked questions
How do I convert PNG to PDF?
Add your PNG files to the converter, arrange them in the order you want, then pick a page size, orientation and margin. Create the PDF and download it. Each image becomes one page of a single file, and it all happens in your browser.
Can I combine many images into one PDF?
Yes. Add as many images as you need, in PNG, JPG or WEBP format, then reorder them and remove any you do not want. They all go into a single PDF, one image per page, in the order shown in your list.
Which page size should I choose?
Choose A4 if you print or share in most countries outside North America, and Letter for the United States and Canada. Choose fit when you want each page to match its image exactly, which suits screenshots, artwork and mixed shapes.
Can I change the order of the pages?
Yes. Move any image up or down in the list before you create the PDF, and the pages follow that order. You can also remove images you do not want. Check the order carefully, because it sets the page sequence.
Why is my PDF so large?
The PDF holds your images, so big files make a big PDF. Convert large PNG files to JPG first with a sensible quality setting, then build the PDF again. JPG is usually far lighter than PNG for photos and scans.
Are my images uploaded anywhere?
No. The PDF is built in your browser, so your images stay on your device. Nothing is sent to a server or stored, and there is no account to create. This suits private documents, though you should still avoid using shared computers for sensitive files.
