PPM / PNM to TIFF

Why convert PPM to TIFF?

PPM and TIFF are both lossless formats. TIFF is the usual choice for printing, scanning, archiving and professional photo work. TIFF can have a transparent background, PPM can't.

Supports transparent backgrounds

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

Crisp edges for editing and print

TIFF keeps sharp lines and text intact, which makes it the better choice for graphics, screenshots and anything you plan to print.

PPM / PNM vs TIFF: what's the difference?

Property	PPM / PNM	TIFF
Compression type	Lossless (exact pixels, larger files)	Lossless (exact pixels, larger files)
Transparent background	No	Yes
Animation	No	No
Where it opens	None	Safari only
Used for	Simple uncompressed images for scientific and developer tools	Printing, scanning, archiving and professional photo work

What is a PPM / PNM file?

PPM, PGM, PBM and PNM are the Netpbm formats: deliberately simple, uncompressed image files from the 1980s. They store pixels as plain numbers, which makes them easy for programs to read and write.

You'll mostly meet them in scientific computing, image-processing scripts and developer tools - rarely in everyday use.

How to open a PPM / PNM file

GIMP, IrfanView, XnView and Photoshop open Netpbm files, as do Linux image viewers. Windows Photos and browsers can't, so convert to PNG for a lossless, much smaller copy.

Extensions: .ppm, .pgm, .pbm, .pnm
Compression: None
Best for: Scientific and developer tools
Family: Netpbm

What is a TIFF file?

TIFF (Tagged Image File Format) is a high-quality format used in professional photography, printing, scanning and publishing. It's usually saved without lossy compression, so it keeps every detail - and produces large files.

TIFF can store layers, 16-bit color, multiple pages and transparency, which makes it a favorite of print shops and archives. For sharing online, it's far too heavy.

How to open a TIFF file

Windows Photos and Mac Preview open most TIFF files. Photoshop, Lightroom, GIMP and Affinity Photo handle advanced ones with layers or 16-bit color. Browsers generally can't display TIFF, so convert to JPG or PNG to share.

Extensions: .tif, .tiff
Compression: None or lossless (usually)
Transparency: Yes
Best for: Printing, scanning, archiving
