Many thanks to AltoPNGtoPDF and its creators. I find it simply irreplaceable, especially when I need to process a lot of files in a short period of time and not worry about the quality.

I wasn’t able to find a proper app to convert PNG files to PDF documents on my Android smartphone until I found this one. It’s simply awesome. All my problems were solved in one minute!

I find PNGtoPDF a great service. Not just you’re able to convert any PNG image to PDF document in a few clicks, but to manipulate (like, edit or sign) the resulting PDF file.

I often use PNGtoPDF to reduce the size of graphic files stored on my computer and make them easily-shareable. With this app, I’m able to edit and share resulting PDFs without effort. Strongly recommended!

PNGtoPDF works better online than any other image-to-document converter I’ve tested. Simply irreplaceable platform, especially when you have an urgent task and have no time for downloading apps on your device.

The best free web-based converter I know. I appreciate its simplicity and the fact that I can process a lot of files in no time. It’s also a nice option if you want to redact the converted PDF.

I like this converter a lot. Mainly because it enables me to import files from Google Drive and Dropbox and process them online without downloading and installing anything on my Mac.

A simple and convenient browser-based tool for converting PNG images to PDFs on any device you have. I’ve used it on both my phone and PC and it works perfectly fine.

I like the fact that I can convert and edit files directly in my Internet browser on any device. Wasn’t expecting such great result and efficiency from a free app.

PNGtoPDF has been making my life easier for a long time now. The app makes it possible to seamlessly convert any image file to a document, redact the resulting PDF and share it with anybody I want within seconds!
