How to convert PNG to PDF

Drop your PNG files above. They are listed in the order you added them, and each one becomes a page in that order. Remove any you don't want, choose Fit to image, A4 portrait or US Letter, and press Create PDF. The PDF is built by pdf-lib inside your browser and downloads straight away. You can mix in JPG and WebP images if a set of screenshots includes a few photos.

Sharp text and kept transparency

PNG is lossless, which is why screenshots, diagrams, charts and scanned forms are usually saved as PNG. The converter keeps it that way. Each PNG's pixels are stored in the PDF with lossless compression, so small text stays crisp and nothing turns blocky. Transparent areas stay transparent, so a logo or signature with no background sits on a white page instead of a black box.

Choosing a page size

Fit to image makes every page exactly the size of its PNG, one point per pixel, with no white border. That suits screenshots and slides you will read on a screen. A4 portrait and US Letter put each image on a standard page, scaled to fit inside a 24 point margin and centred, which is what you want when the PDF will be printed or uploaded to a form that expects normal pages.

Common uses

People turn PNGs into a PDF to send a set of screenshots as one attachment, to submit scanned pages of an ID or a signed form, to hand in photographed homework, or to share design mockups in a file anyone can open. A single PDF keeps the pages in order and opens the same way on Windows, Mac, iPhone and Android.

Before you start

Input: PNG, JPG, JPEG, and WEBP. Output: PDF. The settings appear before anything runs, so you can check them first. Your original file is never changed.

Pick the size and quality for where the image will end up. Resizing before strong compression usually keeps more visible detail. Keep an untouched original so you can export again later.

Keep the original until you have opened and checked the result. The work happens in this browser tab, so the size you can handle depends on your device's memory, your browser and the file itself.
