Why convert PNG to PDF?

The main difference: PNG is a lossless format, while PDF is a document format.

Transparent areas stay transparent

PNG and PDF both handle transparency, so anything see-through in the original is still see-through after conversion.

One file to print, email or submit

A PDF looks identical on every screen and printer, and it's the format most application forms, schools and offices want.

What is a PNG file?

PNG (Portable Network Graphics) is a lossless image format created in 1996 as a patent-free replacement for GIF. It stores every pixel exactly, so text, logos and sharp edges stay perfectly crisp however often you save the file.

PNG supports full transparency, which makes it the standard format for logos, icons, screenshots and graphics placed on top of other designs. For photos, though, PNG files are several times larger than JPG.

How to open a PNG file

PNG opens everywhere: Windows Photos, Mac Preview, iPhone and Android galleries and every web browser. Editors like Photoshop, GIMP, Figma and Canva keep the transparency intact.

Extension: .png
Compression: Lossless
Transparency: Yes
Best for: Logos, screenshots, graphics, text

What is a PDF file?

PDF (Portable Document Format) was created by Adobe in 1993 to make documents look identical on every screen and printer. A PDF can contain text, vector graphics and images across any number of pages.

It's the standard for forms, contracts, resumes, school assignments and anything you print or submit. Turning photos and scans into a PDF bundles them into one tidy, universally readable file.

How to open a PDF file

Every web browser opens PDFs, as do Mac Preview, the Files app on iPhone and the free Adobe Acrobat Reader on Windows, Mac and Android. To get pictures out of a PDF, convert its pages to JPG or PNG.
