If you have image files taking up storage space on your hard drive or mobile device, like PNG files of recipes or tax files, you can quickly convert and store them as PDF documents online. Converting a PNG file to the PDF format also lets you share the image more easily on any device without losing quality.

The Acrobat online PNG image converter makes it easy to convert an image file into a high-quality PDF document. Just select the PNG image you want to convert, or drag and drop your image file into the PDF conversion tool. You can then save the new PDF file on your device.

To merge multiple PNG files into one PDF file, you first need to use the Acrobat PDF online tool above to convert an image file and download the converted PDF. Then sign in to Acrobat to convert another image file to PDF and download it. You can then start an Adobe Acrobat Pro 7-day free trial to use the Merge PDFs tool to combine your new PDF files into a single PDF file.

The Acrobat Pro free trial for Mac or Windows also lets you convert PDFs to other files types like Microsoft Office (DOCX, PowerPoint, and more), annotate or edit PDF documents, edit scans with OCR, crop PDF files, change page size, reduce file size, split a PDF into multiple PDF files, password-protect a PDF, and more.

The Acrobat online tool also lets you quickly and easily convert JPG, BMP, GIF, and TIFF image formats into PDF documents from your web browser or mobile device.
