Convert PNG to PDF

How to Convert PNG to PDF

1

Add your PNGs

Click “Select images” or drag PNG files into the upload area. JPG, WebP, GIF, BMP, AVIF and SVG work here too — you don’t need a separate tool for each.

2

Order and set up the page

Drag to reorder. Choose A4 or US Letter and portrait or landscape. Each image becomes one page, scaled to fit with its aspect ratio intact.

3

Convert and download

Click “Convert to PDF”. The file saves to your Downloads and the original PNGs stay untouched on your device.

Every step runs in your browser. No server uploads, no waiting.

Why use this tool

DukPdf’s PNG to PDF tool turns one or more PNG images into a single PDF document inside your browser. Most PNGs are screenshots, so this is the fastest way to package a run of screen grabs — a bug report, a chat thread, a set of receipts — into one file someone else can open. PNGs are embedded without re-compression, so nothing is degraded on the way in. Going the other way? PDF to PNG pulls pages back out as images. Mixed formats are fine too — JPG to PDF is the same tool under a different name.

When you'd use this

Bug reports

Bundle a sequence of screenshots into one PDF so a developer sees the steps in order instead of hunting through an album.

Chat and email threads

Turn screenshots of a conversation into a single dated document — useful for disputes, HR records, or landlord correspondence.

Design mockups

Send a client one PDF of exported screens rather than a folder of loose PNGs that arrive out of order.

Screenshotted receipts

Combine order-confirmation screenshots into one expense-claim attachment. Purchase details never leave your device.

PNG to PDF — questions

What happens to transparent areas in my PNG?

They are filled with white. PDF pages have no transparency layer, so a see-through background has to resolve to something — white matches what you see in an image viewer and what prints. If you need the transparency preserved, keep the PNG alongside the PDF.

Will my screenshots lose quality?

No. PNG is lossless and the image is embedded as-is, with no re-compression step. A screenshot in the PDF is pixel-for-pixel the screenshot you started with.

Why is my PDF larger than the PNGs I added?

PNG compression suits flat colour and text, and PDF keeps that data intact rather than shrinking it. Screenshots stay crisp but the file grows. Run the result through Compress PDF if you need to email it.

Can I mix PNGs with JPGs and other formats?

Yes. Add PNG, JPG, WebP, GIF, BMP, AVIF and SVG in the same batch and they will be combined in the order you arrange them.

How many PNGs can I convert at once?

Up to 50 images per PDF. Drag the thumbnails to control which one lands on which page.

Are my screenshots uploaded anywhere?

No. The conversion runs in your browser. Open DevTools → Network while converting and you will see no request carrying your images.
