PNG to PDF

Convert PNG screenshots, scans and graphics into one PDF. Choose Fit to image, A4 or US Letter pages, control margins and download a multi-page document in the selected order.

PNG supports transparency, while a PDF page is normally viewed against a page background. Check transparent logos, diagrams and screenshots in the downloaded PDF because appearance can vary with the source PNG and PDF viewer.

How the browser process works

Combine one or more PNG images into a multi-page PDF using the existing browser converter, with Fit to image, A4 or US Letter page sizes and adjustable margins. The page sends the selected file and settings to its images-to-pdf browser engine, creates a new output and downloads it without overwriting the source.

The existing converter keeps PNG image order and aspect ratio while placing each image on its PDF page. Complex transparency appearance can depend on the PDF viewer and source image.

Privacy, quality checks and limitations

  • Keep the original file until the downloaded output has been opened and checked.
  • Verify page count, orientation, dimensions, text legibility, audio/video duration and metadata relevant to your use.
  • Browser-local processing reduces routine upload exposure, but your device, browser extensions and download location still matter.
  • A converted preview is not proof of legal authenticity, archival compliance, accessibility or digital-signature validity.

Use PNG to PDF when screenshots, scanned pages, diagrams or lossless graphics need to be shared as one document. Each PNG becomes a PDF page, and the page-size control lets you keep source dimensions or place the image on A4 or US Letter.

How to convert PNG to PDF

  • Choose the PNG screenshots, scans or graphics.
  • Confirm the order in which they should appear.
  • Choose Fit to image, A4 portrait or US Letter.
  • Set a margin if the content needs space around the page edge.
  • Create and download the PDF, then inspect the result.

PNG to PDF worked example

For a four-step software guide, select step-1.png through step-4.png in sequence and choose A4. The converter creates a four-page PDF with one screenshot on each page, scaled proportionally inside the chosen margin.

If labels look too small, the source screenshots may have too little resolution for the chosen page size. Use Fit to image or provide higher-resolution PNG files rather than assuming that PDF conversion can recreate missing detail.

Choose the right PNG page setting

Fit to imageKeeps a page close to the PNG's own pixel dimensions.
A4 portraitUseful for document-style sharing, printing and many submission workflows.
US LetterUseful when a US Letter page is specifically expected.
TransparencyMay reveal the PDF page or viewer background; inspect the downloaded file.

PNG quality and output checks

  • Small labels and line art are readable at normal zoom.
  • Transparent areas display as expected.
  • Each screenshot or scan appears on the correct page.
  • No page contains unintended blank space from an unsuitable margin.
  • The receiving service accepts image-based PDF pages.

Frequently asked questions

How do I convert PNG to PDF?

Choose your PNG files, select Fit to image, A4 or US Letter, set the margin and create the PDF. Each selected PNG becomes one page in the output document.

Can I combine several PNG screenshots into one PDF?

Yes. Select multiple screenshots in the required order. The converter places them into one multi-page PDF.

Does PNG to PDF keep sharp text and diagrams?

The source PNG is embedded as image content rather than converted to JPG. Readability still depends on the original PNG resolution and the amount of scaling needed for the selected PDF page.

What happens to PNG transparency in a PDF?

The PNG is placed on a PDF page, and transparent areas may show the page or viewer background. Check the downloaded PDF when transparency is important.

Can I make an A4 PDF from PNG images?

Yes. Choose A4 portrait and the tool proportionally centres each PNG inside the page margins.

Will my original PNG files be changed?

No. The converter creates a new PDF for download. Keep the source PNG files until you have verified the result.
