Will my PNG transparency be preserved in the PDF?

Transparent areas are flattened onto a white background before embedding so the PDF prints cleanly and renders consistently across viewers. If you need transparency-preserving PNGs, keep the original files alongside the PDF.

Can I mix PNG and JPG in the same PDF?

Yes. Drop a folder with both formats. PNGs are flattened to white-background JPEG inside the PDF for predictable size; JPGs are embedded as-is for maximum fidelity. The page order in the final PDF matches the order of thumbnails on screen.

Why does Fit-to-image work so well for retina screenshots?

macOS and iOS screenshots are PNGs at twice the on-screen pixel density. Fit-to-image creates a PDF page that exactly matches each screenshot's aspect ratio, so nothing is cropped, scaled, or letterboxed — perfect for design reviews and bug reports.

What page sizes are supported and is anything uploaded?

Fit-to-image (one page per source PNG at its exact aspect ratio), US Letter (8.5 × 11 in), and A4 (210 × 297 mm), each with a custom margin. The whole conversion runs locally in your browser via pdf-lib — your screenshots never leave your device.

What is PNG to PDF?

PNG to PDF combines one or many PNG screenshots, logos, diagrams, or design exports into a single PDF document. PDFs preserve page order, paper size, and orientation across every device and printer — turning a folder of loose PNG screenshots into a single attachment that is easy to email, e-sign, archive, or print. JPG inputs are accepted in the same batch so you can mix screen-grabs and photos in one document.

Page sizes and fit modes

Pick A4 or US Letter for documents that may be printed; pick Fit to image when you want each page to match the source picture's exact aspect ratio (great for screenshots and product shots). The tool keeps the original aspect ratio inside any chosen page size, so images are never stretched — they're scaled and centered with a clean margin.

Is it private?

Yes. The whole conversion happens in your browser using pdf-lib. Your images are never uploaded. There is no file-size limit imposed by a server, and the tool works offline once the page has loaded.

Why convert PNG to PDF?

One PDF, exact order — design reviews and bug reports become a single, paginated document instead of a zip of loose screenshots.
Looks identical everywhere — PNG renders differently in Slack previews, email inline, and on Windows vs macOS; PDF locks the layout so reviewers see exactly what you packaged.
Retina-perfect Fit-to-image — each PDF page matches the PNG's exact aspect ratio so high-DPI screenshots are never cropped or scaled.
Print-ready for whiteboards — drop in mockups, sign-offs, or wireframes and print on A4 / US Letter with consistent margins.
Compact file size — PNGs are flattened to JPEG inside the PDF, so a 50-screenshot review is a few MB instead of hundreds.
