Portable Pixmap Format (PPM) is an uncompressed, raster-based colour image format from the Netpbm family. A PPM file stores a plain header followed by RGB values for every pixel, either as readable ASCII text or as binary data. Because nothing is compressed or discarded, PPM is deliberately simple for programs to read and write, at the cost of very large file sizes.

 

How to open a PPM file?

Most operating systems do not open PPM by default. XnView MP and GIMP both read it, and on Windows IrfanView opens PPM as well.

 

PPM is mainly used as an intermediate format in image-processing pipelines rather than for storage or sharing. Because of its size, convert PPM to a compressed format before publishing it online — try our PPM to JPG converter. Related Netpbm types are PBM (bitmap), PGM (greyscale), and PNM (any of the three).

JPEG (Joint Photographic Experts Group), is a universal file format that utilizes an algorithm to compress photographs and graphics. The considerable compression that JPEG offers is the reason for its wide use. As such, the relatively small size of JPEG files makes them excellent for transporting over the Internet and using on websites. You can use our compress JPEG tool to reduce the file size by up to 80%!

 

If you need even better compression, you can convert JPG to WebP, which is a newer and more compressible file format.

 

How to open a JPEG file?

Almost all image-viewer programs and applications recognize and can open JPEG files. Simply double-clicking the JPEG file will usually result in its opening in your default image viewer, image editor, or web browser. To select a specific application to open the file, utilize right-click, and select "Open with" to make your selection.

 

JPEG files open automatically on popular web browsers such as Chrome, Microsoft applications such as Microsoft Photos, and Mac OS applications such as Apple Preview.
