Private image conversion
Your images are read and placed into the PDF by your browser. No file is sent to a server or stored remotely. Your images exist only in your browser's memory while this page is open.
How PNG images are placed
PNG is lossless, and the PDF keeps it that way: the original PNG data is embedded directly, so screenshots, diagrams, and line art stay pixel-exact. Transparent areas are placed over the white page.
- Lossless source, lossless PDF
- No re-compression. Sharp text and flat colours in screenshots stay crisp.
- Transparency on white
- PDF pages are white, so transparent regions appear white. The transparency itself is preserved inside the file.
- One image per page
- Each image is scaled to fit its page without cropping or stretching and centred within the margin.
Page layout
Every image is placed on its own page, scaled to fit without cropping or stretching, and centred. Pages are white, so transparent areas show as white.
- Page size
- A4: 210 × 297 mm, the standard everywhere except North America. Letter: 8.5 × 11 in, the standard in the US and Canada. Fit to image: Each page takes the exact shape of its image, plus the margin.
- Orientation
- Auto: Landscape for wide images, portrait for tall ones. Portrait: Every page is taller than it is wide. Landscape: Every page is wider than it is tall.
- Margin
- None: The image reaches the page edge. Small: 10 mm of white space around the image. Medium: 20 mm of white space around the image.
Frequently asked questions
- Are my images uploaded?
- No. The PDF is assembled entirely in your browser. This site has no upload endpoint, and your images never leave your device.
- What happens to transparent PNGs?
- The image is placed on a white page, so transparent areas look white. The PDF still stores the transparency, which matters if you later place the page on another background.
- Can I combine several PNGs into one PDF?
- Yes. Select as many as you like, or add more later. Each image becomes its own page, in the order shown in the list.
- Does the PDF keep full quality?
- Yes. PNG data is embedded without re-encoding. The PDF will be roughly the combined size of your images.
- Which page size should I choose?
- A4 and Letter give you standard printable pages. Fit to image makes each page exactly the shape of its image, which suits screenshots and graphics.
- What is the name of the PDF?
- A single image keeps its own name, so diagram.png becomes diagram.pdf. Several images produce images.pdf.
