JPG to PDF

Why convert JPG to PDF?

The main difference: JPG is a lossy format, while PDF is a document format. PDF can have a transparent background, JPG can't.

Supports transparent backgrounds

PDF can hold a transparent background. Convert your image first, then cut out the background or place it on top of other designs.

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 JPG file?

JPG (also written JPEG, from the Joint Photographic Experts Group that created it in 1992) is the most widely used photo format in the world. Phones, cameras, websites, email and social networks all handle it.

JPG uses lossy compression: it discards fine detail your eye barely notices, which makes photos 5-10 times smaller than an uncompressed copy. The trade-off is that every re-save loses a little more detail, and it can't store a transparent background.

How to open a JPG file

Every device opens JPG files out of the box: Photos on Windows and Mac, the Photos or Gallery app on iPhone and Android, and any web browser. To edit one, use Photoshop, GIMP, Canva or the free tools on ConvertPixels.

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.
