Up to 20 static PNG images · 20 MB and 24 megapixels each · 100 MB total

How to use

  1. Choose up to 20 static PNG images. Each file becomes one PDF page.
  2. Reorder the previews and select paper size, orientation and margins.
  3. Create the PDF, download it and check the page order in your PDF viewer.

Example

Three 1200 × 1600 PNG screenshots → three A4 pages, with 6.35 mm margins.

Details and limitations

PNG pixels are embedded losslessly after browser decoding, with alpha transparency. There is no intermediate JPEG conversion. PDF viewers normally display a white page behind transparent areas.

Image-size pages use 96 pixels per inch. A4 and Letter fit the whole image inside the margins without cropping. This does not perform OCR or make screenshot text editable.

FAQ

Will PNG transparency be kept?

Yes. The PDF image includes transparency; its visible background depends on the PDF page and viewer. The converter does not flatten the PNG onto a JPEG.
