PNG to PDF Converter
Convert PNG images to PDF free — combine multiple files into one document. Entirely in your browser. No upload, no account, no watermarks.
PDF embeds raster images as compressed streams — your PNG pixels are stored inside the document using DEFLATE or JPEG encoding depending on the library. The key consideration for print is DPI: a 1200×1600 PNG looks sharp on screen at 96 DPI, but when printed on A4 at 300 DPI it maps to a 4×5-inch area. For a PNG to fill a full A4 page at print resolution, the source should be at least 2480×3508 pixels.
The most common reason to convert PNG to PDF is submission requirements. Email systems, legal filing portals, university assignment platforms, and HR software overwhelmingly prefer PDF over raw image files because PDF locks layout across every viewer — a PNG that renders correctly on your display may appear at different zoom levels or aspect ratios on another device or OS. Converting to PDF eliminates that inconsistency.
Multiple PNGs can be combined into a single multi-page document, useful for assembling screenshots into a report, packaging design export frames for client review, or bundling scanned pages for a legal filing. For smaller output files, run your PNGs through the PNG compressorbefore converting — the tool embeds images at their current quality, so compressing first produces a noticeably smaller PDF.

How to convert PNG to PDF
Drop your PNG files above, reorder by dragging if needed, choose your page size, then click Convert to PDF. The PDF downloads instantly. Transparent PNGs are placed on a white background in the PDF — PDF does not support transparency natively.
Frequently asked questions
Can I combine multiple PNG files into one PDF?
Yes — drop multiple PNGs, drag to reorder them, then convert. Each PNG becomes one page. This is ideal for combining screenshots, diagrams, or design exports into a single shareable document.
Does PNG transparency carry over into the PDF?
PDF does not natively support PNG-style alpha transparency in the same way. Transparent areas in your PNG will be placed on a white background in the PDF output. If you need to preserve transparency, consider keeping the file as PNG or SVG instead.
What page size should I use?
For printing or formal documents, use A4 or Letter. For digital documents where each page should match the exact PNG dimensions (e.g., screenshots or diagrams), use Fit-to-image.
Are my PNG files uploaded to a server?
No — the PDF is generated entirely in your browser using jsPDF. Your files never leave your device.
How do I convert PNG to PDF on Mac?
Open this page in any browser on Mac — Chrome, Safari, or Firefox. Drop your PNG files and click Convert to PDF. No software required. Alternatively, on Mac you can open a PNG in Preview and use File → Export as PDF, but that only works one file at a time — this tool handles multiple PNGs at once.
Can I also convert JPG files in the same PDF?
Yes — the tool accepts JPG, PNG, WebP, and GIF in the same batch. Mix formats freely. For a dedicated JPG converter, see the JPG to PDF converter.
How do I extract the PNG images back from the PDF?
Use the PDF to JPG converter to extract each page as an image. Note the output will be JPG — if you need PNG, use the JPG to PNG converter afterwards.
Why convert PNG to PDF?
PDF is the standard format for sharing documents professionally — every device can open it without special software, and the layout is preserved exactly. Converting PNG screenshots, diagrams, or design exports to PDF makes them easier to share via email, attach to reports, or submit to systems that require PDF format. A PDF also bundles multiple images into a single file, reducing clutter.
Can I combine multiple PNG files into one PDF?
Yes — drop multiple PNG files, drag them to set the order, then click Convert to PDF. Each PNG becomes one page in the resulting document. This is particularly useful for combining a sequence of screenshots, design mockups, or presentation slides into a single shareable PDF.
Does PNG to PDF preserve transparency?
PDF pages have opaque white backgrounds by default. Transparent areas in your PNG are filled with white when placed on a PDF page — the alpha channel is not preserved. If keeping transparency is important, consider keeping the file as a PNG or SVG rather than converting to PDF.
What is the PDF page size for a PNG image?
By default the tool maps PNG pixel dimensions to PDF units at 72 DPI, resulting in a page that matches the image proportions. You can also choose A4 or Letter page sizes, which scale the image to fill the page while maintaining aspect ratio. For screenshots where you want the page to exactly match the image, use the Fit-to-image option.
How do I convert a screenshot to PDF?
Take your screenshot (it saves as a PNG on most systems), then drag the file onto this tool and click Convert to PDF. The entire process takes under 10 seconds and runs entirely in your browser — no software installation needed. For multiple screenshots, drop them all at once to combine into a single multi-page PDF.
