How to convert PNG images to a PDF

PNG is a screenshot and graphics format; PDF is a document format. Converting between them is less about pixels and more about layout — how each image is placed on a page, in what order, and at what size. Here is how to get a clean result rather than a stack of oddly cropped pages.

JPG, PNG or WebP. Drag and drop, or choose from your device.

Up to 50 MB per file. Files are processed in your browser.

When you actually need this

  • Uploading proof of something — a screenshot of a receipt, confirmation or bank transfer — to a portal that only accepts PDF.
  • Bundling a set of design exports or diagrams into one document a client can page through.
  • Submitting coursework or evidence where a single file is required instead of a dozen loose images.
  • Archiving screenshots so they stay in a fixed order with fixed page sizes.

Page size is the part people get wrong

A PNG has pixel dimensions, not physical ones. A PDF page has physical dimensions such as A4 or US Letter. The converter has to bridge the two, and the choice it makes decides whether your image fills the page, floats in a sea of white, or gets cropped.

Fitting the image inside a standard page is the safe default when the document will be printed or read alongside other paperwork. Matching the page to the image is better when the images are wide screenshots, because it avoids huge margins and keeps text readable without zooming.

Keeping quality intact

PNG is lossless, so nothing is degraded by the conversion itself. The file can get large, though: ten full-resolution screenshots easily add up to 20 MB or more. If the finished PDF needs to be emailed, run it through the compressor afterwards rather than shrinking the images first — you keep more control that way.

Screenshots with fine text are the exception. Compress those lightly, if at all, because heavy compression is what turns crisp UI text into a smudge.

Step by step

  1. 1Add your PNG files to the tool below. You can select several at once.
  2. 2Drag the thumbnails into the order you want the pages to appear.
  3. 3Choose a page size — A4 or Letter for documents, or match-image for wide screenshots.
  4. 4Pick portrait or landscape based on the shape of most of your images.
  5. 5Generate the PDF, open it, and check that nothing is cropped at the edges before you send it.

Frequently asked questions

Can I mix PNG and JPG files in the same PDF?
Yes. The tool accepts both formats together, so a set of photos and screenshots can go into one document without converting anything first.
Will transparent areas of the PNG stay transparent?
No. PDF pages have a background, so transparent pixels are rendered as white. If a logo relies on transparency, place it on the background colour you want before converting.
Is there a limit on how many images I can add?
There is no fixed limit, but everything is processed by your own device, so a hundred high-resolution images will take noticeably longer than ten.
