How to convert PNG and JPG pictures to one PDF

Read the transcript

Here's how to convert PNG and JPG pictures into one PDF, free, right in your browser, without uploading a thing.

Drop your pictures onto the PNG to PDF tool. They open right on this page, so nobody else ever sees them.

Click the arrows under a page to move it earlier or later, until your pictures are in the order you want.

Choose Picture size to keep each page the shape of its picture, or pick A4 or US Letter when you want to print. Then click Download, and that's your PDF.

A see-through PNG stays see-through in the PDF, so its clear parts show the white page behind them.

And if your specials change every day, save the special poster once in thirds.ai. Type in today's dish, and you get a fresh poster in your café's colours.

Make your next poster on thirds.ai.

PNG to PDF conversion example

In this PNG to PDF example, a café's 1080 × 1350 opening hours poster becomes a one-page A4 PDF that's ready to print. You choose A4, and the poster sits in the middle of the page with a half-inch white edge, so a home printer doesn't cut it off.

How it works

How to convert PNG to PDF

  1. Step 1

    Drop in your pictures

    Drag PNG, JPG, or WebP pictures onto the page, or choose several at once. They open right here in your browser, so nothing uploads.

  2. Step 2

    Put the pages in order

    Each picture becomes one page. Use the arrows under a page to move it earlier or later, or remove it. Click Add more pictures to add pages at the end.

  3. Step 3

    Pick the page size and download

    Choose Picture size, A4, or US Letter, then click Download PDF. The PDF takes the name of your first picture.

Questions about this tool

Does this upload my pictures?

No. Your pictures open on this page in your browser, and the PDF is made there too. You don't need an account, and we never see the files.

Can I convert JPG to PDF too?

Yes. You can mix PNG, JPG, and WebP pictures in one PDF. Each picture becomes one page, in the order you set.

Which page size should I pick?

Choose Picture size for a PDF you share on a screen, because each page fits its picture with no white edge. Choose A4 or US Letter to print. A wide picture gets a sideways page.

Will my pictures lose quality?

A PNG or WebP goes into the PDF with every pixel. A JPG is saved again as a high-quality JPG, so it keeps its size in pixels and looks the same.

How many pictures can I add?

You can add up to 30 pictures, each up to 10 MB. The finished PDF can be up to 25 MB. If it's bigger, use fewer pictures, or use JPG files for photos.

What about transparent backgrounds?

The see-through parts of a PNG stay see-through in the PDF, so they show the white page behind them.

Is this free?

Yes. The download from this page costs nothing. A file from a saved template still costs one credit.
