Lossless, transparency included

PNG is embedded natively in PDF with no re-encoding, so screenshots and graphics keep every pixel and their transparency. A PNG with a transparent background produces a page whose blank areas are genuinely empty, which is exactly what you want for a logo or a signature you will place on another document.

Each PNG becomes a page of its own pixel dimensions, in the order you added the files. Screenshots taken on a Retina or high-DPI display therefore make large pages; readers scale them to fit.

Size trade-off

Because PNG is lossless, a PDF made of photographic PNGs can be large. For photos, converting to JPG first (PNG to JPG) and then to PDF gives a file several times smaller with no visible difference. For screenshots, diagrams and text-heavy images, keep PNG — JPEG would blur the edges.

If you need one document from a mix of screenshots and photos, use Image to PDF, which accepts every format at once.

FAQ

Common questions

Can I combine multiple images?

Yes. Add several images and they're merged into a single PDF, one image per page.

Are my files uploaded?

No. The conversion runs entirely in your browser using JavaScript — your file never leaves your device, so it's safe even for sensitive documents.

Is it free?

Yes — completely free, no signup, no watermark, and no daily limits.

Will the transparent background stay transparent?

Yes. PDF supports PNG transparency natively and the image is embedded without changes, so the page shows through wherever the PNG was transparent.

Why is the PDF the same size as my PNGs?

The PNG data is stored inside the PDF unchanged. The PDF adds only a few hundred bytes of structure per page.
