PNG to PDF - Free Online Browser Tool

Convert transparent or solid PNG images to PDF.

PNG is the format screenshots, diagrams and exported charts come in, and those rarely belong in a document as loose attachments. This tool collects PNGs into a single PDF, compositing transparent areas onto white so nothing renders as a black box in a reader that lacks alpha support.

This png to pdf utility runs completely inside your web browser. Your document is opened locally and processed on your own device using JavaScript and WebAssembly, so your file is never uploaded to any server. There is no signup, no watermark and no limit on how many documents you can handle.

  • 100% client-side - files never leave your device
  • Instant processing, no upload wait
  • Works on desktop, tablet and mobile
  • Free forever, no account required

How to Use the PNG to PDF Tool

Four steps, and the whole thing runs locally on your own device.

  1. Drop in your PNG files

    Add one or several PNGs — screenshots, exports, diagrams. Order them by dragging the chips.

  2. Choose a page treatment

    Give each image a page matched to its own proportions, or fit it onto standard A4 or Letter sheets.

  3. Build the PDF

    Transparent regions are composited onto a white background during conversion so every PDF reader shows them correctly.

  4. Download

    Save the multi-page PDF. Your PNG originals stay exactly as they are.

Frequently Asked Questions

How are transparent areas handled?

PDF pages have no alpha channel of their own, so transparency is flattened onto white. That renders correctly everywhere, but a transparent logo loses its see-through quality over a coloured page.

Do PNGs get re-compressed and look worse?

No. PNG is lossless and the data is embedded as-is, so there is no quality loss at any point.

Can I build a PDF from mixed JPG and PNG files?

Yes. Use <a href="https://www.allpdf.tech/images-to-pdf/multi-img-to-pdf" class="seo-link">Batch Images to PDF</a>, which accepts any image format in one queue — this tool is the PNG-focused equivalent.

Will a screenshot’s text stay sharp?

Yes. Because nothing is resampled, small UI text remains legible. Print at a larger paper size if you need it larger on the page.

Can I control the order of pages?

Yes — each image is a chip you can drag up or down, or remove entirely, before you build the document.
