How to use PNG to PDF

  1. 1

    Add the PNG files

    Drop up to 10 PNG screenshots, diagrams or scans, pick them with the file chooser, or paste a screenshot straight from the clipboard with Ctrl+V.

  2. 2

    Arrange the pages

    Drag the previews into reading order; press and hold to drag on a phone. Use the rotate button for any image that should lie on its side.

  3. 3

    Choose the paper

    Keep A4, switch to US Letter or Legal, or pick Same as image so every page takes its screenshot's exact proportions.

  4. 4

    Download the PDF

    Give the document a name and press Create PDF; the pages follow the order of the previews.

Limits and Pro

Up to 10 images per PDF, each up to 50 MB.

Pro combines up to 500 images of up to 4 GB each into one PDF. See Pro

About PNG to PDF

PNG files carry their pixels without loss, and this conversion keeps it that way. Each PNG is decoded and written into the PDF with lossless compression, so screenshots of code, spreadsheets, chat threads and user interfaces stay razor sharp, and a diagram's thin lines and flat colours come through untouched. Transparent areas remain transparent inside the PDF, which shows them over the white page; a logo with a soft shadow keeps its smooth edge instead of picking up a black or checkered box.

Screenshots rarely match a paper size, so the page layout matters more here than with photos. Same as image makes each page exactly the screenshot's shape at 96 pixels per inch, which reads well on screen and avoids white borders, though a wide 2560-pixel capture becomes a page more than 26 inches across when printed. A4 or Letter with Fit keeps a uniform document for printing or for a portal that checks the paper size, and Auto orientation turns pages landscape for wide captures.

Typical jobs are bundling a sequence of screenshots for a support ticket or a how-to guide, collecting scanned forms saved as PNG into one file, and handing in diagrams as a single attachment. Because nothing is recompressed, a PDF of many large PNGs is about as heavy as the PNGs themselves; run it through a PDF compressor afterwards if an email size limit gets in the way. Any other image format can be mixed in, and JPG, WebP or HEIC files dropped alongside are handled too.

Privacy

The PNG files are read in this tab and the PDF is assembled by pdf-lib in a Web Worker on your device, so the screenshots, which often show private messages or account details, are never uploaded anywhere. The page doesn't keep a copy after you close it.

Features

Lossless pages

PNG pixels go into the PDF unchanged, so text in screenshots stays crisp.

Transparency kept

See-through areas and soft edges stay transparent over the white page.

Paste screenshots

Add captures straight from the clipboard with Ctrl+V or Cmd+V.

Pages that fit

Same-as-image pages for the screen, or A4 and Letter with automatic orientation for print.

PNG to PDF: frequently asked questions

Does converting PNG to PDF reduce the quality?
No. PNG images go into the PDF through lossless compression, so every pixel stays exactly as it was and text in screenshots stays sharp at any zoom level. The page size you pick only changes how large the image is shown on the paper, never its pixel count. Only formats PDF can't store natively, such as WebP or HEIC, are converted to JPEG on the way in.
What happens to transparency in my PNG?
It is kept. Transparent and semi-transparent pixels are stored with a soft mask in the PDF, so a viewer draws the image over the page and you see white wherever the PNG was see-through. Logos, icons and diagrams with soft edges or drop shadows therefore look the same as in an image viewer, without a black background appearing behind them.
Which page size suits screenshots best?
For reading on screen choose Same as image: each page is cut to its screenshot, with no white borders and nothing scaled down. If the PDF will be printed or uploaded to a form that expects A4 or Letter, keep a paper size with Fit and leave orientation on Auto, so wide desktop captures get landscape pages and phone screenshots get portrait ones.
Can I paste a screenshot instead of saving it as a file first?
Yes. Take the screenshot with Print Screen, Win+Shift+S or Cmd+Ctrl+Shift+4, then press Ctrl+V or Cmd+V on this page: the image from the clipboard is added as the next page, just like a dropped PNG. You can paste several captures one after another and reorder them afterwards by dragging the previews.
Why is my PDF as large as all the PNGs together?
Because lossless means the image data is not thrown away: the PDF holds the same pixels the PNG files did, compressed in a similar way. Photo-like PNGs, such as camera pictures saved as PNG, are especially heavy. If the size matters more than perfect pixels, compress the finished PDF, which turns photo-like images into JPEG while keeping text sharp.
