Convert PNG to PDF — overview

To convert PNG to PDF on Mac or Windows, you have five practical options. The right pick depends on how many images you have, whether the content is sensitive, and whether you already pay for Adobe Acrobat or want a free path.

Use the table of contents above to jump to whichever method fits, or read on for the why-and-how of each.

Method 1: Multi PDF Converter (recommended for many files)

Multi PDF Converter is a desktop app for Windows and macOS that converts PNG (and JPG/JPEG) images to PDF files locally on your computer. It's the right pick when you have more than a handful of PNGs to convert, when content shouldn't be uploaded, or when you want one tool that handles both image-to-PDF and PDF-to-image directions.

5-step process: convert PNG to PDF Five sequential steps — download, pick PDF as the output, add images, convert, open the PDFs. 1 Download free trial 2 Pick PDF output format 3 Add PNGs drag & drop 4 Convert pick output folder 5 Done PDFs written
Two minutes total for most batches.
Pros
  • Handles many images in one job
  • Files never leave your computer
  • Native Windows + macOS builds
  • Same tool also converts PDF to PNG, PDF to JPG, and JPG to PDF
  • Lossless conversion — PNG quality preserved exactly
  • 30-day money-back guarantee
Cons
  • Requires download and install
  • Paid app (subscription) with a free trial
  • Creates one PDF per image — see merge vs. convert if you want all PNGs in a single combined PDF

Step 1: Download Multi PDF Converter

This runs locally on your machine. Download the free trial for Windows or macOS. Try it on your own images before you buy.

Step 2: Pick PDF as the output

Open Multi PDF Converter and click PDF in Convert to JPG · PNG · WebP · PDF at the top of the window. The same step also turns JPG, iPhone HEIC and WebP images into PDFs.

Step 3: Add your PNG images

Drag your PNG files into the window, all at once, or drop the whole folder they are in (subfolders included). Or click Click here to choose files; once files are listed, Add Files adds more.

Step 4: Convert and pick an output folder

Click Convert to PDF and choose where to save. Multi PDF Converter writes one PDF for each image into a Converted Files folder inside the folder you pick. Your original PNG files are left untouched.

Step 5: Open the converted PDFs

Each input PNG produces a PDF with the same filename. PNG is a lossless format and the conversion preserves pixel-perfect quality — the PDF looks identical to the source image.

Method 2: macOS Preview (free on Mac)

If you're on a Mac and need to convert a single PNG to PDF — or a small handful — Preview is built into macOS and free. Open the PNG in Preview, choose File → Export as PDF, name the file, save.

For a quick combine — multiple PNGs into a single multi-page PDF — select all the images in Finder, right-click → Open With → Preview, then File → Print → PDF dropdown → Save as PDF. Preview produces one PDF with each image on its own page.

Pros
  • Already installed on every Mac
  • Free, no install, no signup
  • Handles both single conversion and image-stitch into one PDF
Cons
  • Mac only
  • Awkward for large batches — no progress bar, no batch UX
  • Print-to-PDF workflow hidden under File → Print, not File → Export

Method 3: Windows Photos / Print to PDF (free on Windows)

Windows 10 and 11 include a built-in "Microsoft Print to PDF" virtual printer. Open the PNG in the Photos app, hit Ctrl+P, pick Microsoft Print to PDF as the printer, click Print, save the resulting PDF.

For multiple PNGs in a single PDF, select all of them in File Explorer, right-click → Print, choose Microsoft Print to PDF, then Print. Windows writes one PDF containing each image on its own page.

Pros
  • Already installed on every Windows 10/11 machine
  • Free, no install
  • Handles single conversion and image-stitch into one PDF
Cons
  • Windows only
  • "Print" UI is unintuitive for non-Windows users
  • Default print settings may downsample PNG quality slightly

Method 4: Adobe Acrobat (if you already have a subscription)

If you already pay for Adobe Acrobat Pro, File → Create → PDF from File covers single-PNG conversion. For multiple PNGs into one PDF, Combine Files handles the stitch.

Pros
  • Best if you're already in the Adobe ecosystem
  • Strong Combine Files UI for stitching many images into one PDF
  • Fine-grained page-size and orientation controls
Cons
  • Subscription pricing (~$15–20/month)
  • Overkill for a single-PNG conversion
  • Heavy install, frequent updates

Method 5: Online PNG to PDF converters (caps and privacy tradeoffs)

Browser-based tools let you drag a PNG in and download a PDF. Fine for a one-off non-sensitive image. The catch: every image you upload is sent to a third-party server.

Pros
  • Nothing to install
  • Cross-platform — works on Chromebooks, phones, tablets
  • Fine for tiny non-sensitive files
Cons
  • Every image is uploaded — don't use for screenshots of internal dashboards, signed documents, medical or financial images
  • Free tiers cap file size (typically 5–25 MB)
  • Free tiers throttle to a handful per day
  • Some tools re-encode PNGs as JPG-style lossy compression, defeating the point of using PNG

Convert vs. merge — single PDFs or one combined PDF

Two different outcomes people mean by "convert PNG to PDF":

Pick by what the receiving system wants. If you're uploading individual screenshot PDFs to a portal, convert. If you're producing a single document like "all UI mockups in one file," merge. The methods above cover both: Multi PDF Converter is the convert-each option; macOS Preview, Windows Print to PDF, and Adobe Acrobat Combine all handle the merge-into-one option. You can also convert with Multi PDF Converter, then join the PDFs in any order with Batch PDF Merger.

PNG vs. JPG → PDF — which to pick

If you have control over the source image format, PNG → PDF preserves quality better than JPG → PDF for content that has sharp edges:

If you have a JPG already and need PDF output, see our free JPG to PDF tool.

FAQ — common PNG to PDF questions

Open Multi PDF Converter, pick PDF as the output, drag the PNG file into the window, then click Convert to PDF. The image is saved as a PDF in the output folder you choose. The same workflow handles JPG, HEIC and WebP images and can process many at once.

Multi PDF Converter accepts a batch of PNG files in a single job. Drag every image, or the folder they are in, into the window, pick PDF as the output, and click Convert to PDF. Each PNG is converted to its own PDF in the output folder. For combining multiple PNGs into a single multi-page PDF, see the merge question below.

Multi PDF Converter converts each PNG into a separate PDF file. To stitch PNG images into a single multi-page PDF (one image per page), the simplest free option on macOS is Preview: select all the PNGs in Finder, open with Preview, then File → Print → PDF → Save as PDF. On Windows, the built-in Photos app lets you select images and "Print to PDF" to produce a single combined PDF.

On a Mac, the simplest built-in option is Preview: open the PNG in Preview, choose File → Export as PDF. For batches of many PNGs, Multi PDF Converter runs natively on macOS and handles them in one job.

On Windows, the built-in Photos app supports Print → Microsoft Print to PDF for individual files. For batches, Multi PDF Converter on Windows accepts many PNGs in one job and writes a PDF for each. Adobe Acrobat Pro also handles PNG to PDF conversion if you already have a subscription.

Online PNG-to-PDF tools upload your images to a third-party server. If the PNGs contain confidential content — screenshots of internal dashboards, signed documents, medical or financial images — use a desktop tool that processes files locally on your computer and never transmits them.

Yes. Converting a PNG to PDF embeds the original image inside a PDF wrapper — the image bytes are preserved and the resulting PDF is the same visual quality as the source PNG. The PDF file will be slightly larger than the PNG because of the PDF container overhead.

PNG is lossless — every pixel of the screenshot is preserved exactly, including sharp text and crisp UI edges. JPG uses lossy compression and can introduce visible artifacts around text and edges. For screenshots, use PNG → PDF if you have the choice. JPG → PDF is fine for photographs but suboptimal for screenshots.
