How to Convert PNG to PDF

Need to send a screenshot, scan, or diagram as a document? Converting PNG to PDF makes your image universally readable, printable, and easy to email. This guide shows you how to do it in seconds using your browser — no software to install, nothing uploaded.

Step-by-step instructions

  1. 1

    Go to the FormatDrop PNG to PDF converter

    Open formatdrop.com/png-to-pdf in your browser. The converter loads pdf-lib directly into your browser tab — no server involved.

    Go to converter
  2. 2

    Upload your PNG file or files

    Drag one or more PNG files onto the drop zone, or click to browse. If you upload multiple PNGs, each image becomes a separate page in the final PDF, in the order you uploaded them.

  3. 3

    Convert your PNG to PDF

    Conversion runs entirely in your browser using pdf-lib. The PNG is embedded at full resolution in the PDF — no re-encoding, no quality loss. The PDF page size matches the image dimensions.

  4. 4

    Download your PDF

    Click the Download button to save the PDF. The file is ready to email, print, or upload anywhere PDFs are accepted.

Why convert PNG to PDF?

PNG is a great format for storing images — lossless, supports transparency, widely supported. But when you need to send a document, share multiple images as a single file, or submit something to an institution that expects a PDF, PNG falls short. PDFs are universally readable on every device and operating system without any special software. They preserve the exact layout and dimensions of your images, render identically across all printers, and are the standard format for formal documents, portfolios, and submissions. Bundling multiple screenshots or diagrams into a single PDF is also far more convenient than sending a folder of image files.

Your files never leave your device

FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.

Frequently asked questions

Can I convert multiple PNGs to one PDF?
Yes. Upload multiple PNG files at once and FormatDrop will combine them into a single PDF, with each PNG as a separate page. The pages appear in the same order as your uploads, so arrange them before uploading if order matters.
Will the PNG quality be preserved in the PDF?
Yes, completely. The PNG is embedded in the PDF at its original resolution — there is no re-encoding or compression step. A 3000×2000 PNG will appear as a 3000×2000 image inside the PDF. Print quality is fully preserved.
