How to convert png to pdf

  1. 1

    Choose your PNGs

    Drop them onto the page — several at once is fine.

  2. 2

    Order them

    Move images earlier or later until they read in the right sequence.

  3. 3

    Pick a page size and download

    Fit image is best for screenshots; A4 or Letter for printing. Then press Create PDF.

Best for screenshots and diagrams

PNG is lossless, and it is embedded into the PDF without re-encoding, so screenshots stay pixel-sharp. Text in a screenshot stays readable rather than picking up JPG halos.

Choose Fit image so each page matches its screenshot exactly, with no white margin and nothing scaled down.

About transparency

PNG transparency is preserved when the image is embedded, but a PDF page is white underneath, so transparent areas simply appear white in most readers and when printed.

If the image is meant to sit over a specific colour or texture, flatten it onto that background in an image editor before converting, rather than relying on the PDF page to supply it.

This also means a logo with a transparent background will look correct on a normal white page without any extra work — the transparency only matters when something else is meant to show through.

Frequently asked questions

Are my images uploaded to convert them?
No. The document is opened and edited by code running in your browser, and the new PDF is generated on your device. There is no upload endpoint in this application — you can watch the network tab while you work.
Can I put multiple PNGs into one PDF?
Yes. Add as many as you want and reorder them; each becomes a page.
Does the PDF lose quality?
No. PNGs are embedded losslessly, so the pages are exactly as sharp as the source images.
Why is my PDF so large?
PNG is lossless and therefore heavy. Convert the images to JPG first if size matters more than perfect sharpness.
