Jak używać PNG to PDF

  1. 1Drop your .png files onto the box above, or click it to browse. Dozens at once is fine.
  2. 2Put them in the order you want with the arrows, then choose a page size and margin.
  3. 3Press create, then download the PDF.

The transparency question, answered first

PNG is the format people reach for when an image needs a transparent background: logos, icons, diagrams exported from design tools, screenshots with rounded corners. So the first thing that matters in a PNG to PDF converter is what happens to that transparency, and the common answer is bad. Flatten it onto black and a dark logo disappears. Flatten it onto white without saying so and a design that was meant to sit on a coloured page arrives wrong.

Here the image is embedded as a PNG inside the document, alpha channel intact. The transparent areas show whatever the PDF viewer paints behind the page, which is white in every ordinary reader, and stay transparent if the page is placed into something else later.

Several images, one document, in your order

Most people arrive with more than one file. A set of exported slides, a diagram per page, a sequence of screenshots for a bug report or a manual. Each image becomes one page, and the list order is the page order, changed with the arrows beside each row before you build.

That is worth doing deliberately, because it is the part no other step can fix. A twelve-page document assembled in the wrong order has to be rebuilt, while choosing the wrong margin costs one more click.

Size, and when to use JPG instead

PNG is lossless, and a PNG stays lossless inside the PDF. For diagrams, screenshots and line art that is exactly right: text edges stay sharp and flat colour areas stay flat. For photographs it is expensive, since a lossless photograph is roughly ten times the size of a good JPEG at a difference nobody sees. If your images are photographs, convert them to JPG first and then build the document.

Everything runs in your browser. Nothing is sent to a server, there is no watermark, and no account is needed.

Najczęściej zadawane pytania

What happens to transparency?
It is kept. A PNG with an alpha channel is embedded into the PDF as a PNG, so the transparent areas stay transparent and show whatever the viewer draws behind them, normally white. This is the one thing converters most often get wrong: flattening onto black is the classic naive result, and it makes a logo unusable.
Can I put several PNGs into one PDF?
Yes. Every image becomes a page, in the order shown in the list, and the arrows next to each row change that order before you build. This is the usual reason people convert png to pdf at all rather than sending the images themselves.
Why is the PDF bigger than the PNG files?
Because PNG is lossless and stays that way inside the document. A screenshot or a diagram carries every pixel exactly, and the PDF is a container around it rather than a new compression pass. If size matters more than exactness and the images are photographic, converting them to JPG first will produce a much smaller document.
What page size should I choose?
Fit-to-image for anything read on a screen, because it gives every page the shape of its image and adds no white bands. A4 or US Letter for anything going to a printer, since those centre the image on a standard sheet and rotate to landscape when it is wider than tall.
Are the files uploaded?
No. They are read and written into the PDF by your own browser. Nothing reaches a server, nothing is stored, and the page keeps working once it has loaded.
