Can I convert TIFF to PPM / PNM on iPhone, Android, Mac or Windows?

Yes. ConvertPixels works in Safari, Chrome, Edge and Firefox on any device, so you can convert TIFF to PPM / PNM on your phone or computer without installing an app.

Is there a free TIFF to PPM converter with no sign-up?

Yes, this one. Converting TIFF to PPM on ConvertPixels is free, with no sign-up, no watermark and no daily cap. Convert up to 30 files per batch, each up to 50 MB.

Can I convert TIFF to PPM without losing quality?

Yes. PPM is a lossless format, so your converted file is pixel-for-pixel the same as the TIFF. (It can't add back detail the original never had.)

Does PPM keep the transparent background of my TIFF?

No - PPM has no transparency, so see-through areas get a solid fill. That's white unless you pick another background color in the options.

Can I batch convert TIFF to PPM?

Yes. Add up to 30 TIFF files and convert them in one batch. You can even choose a different output format for individual files, then download them separately or together as a ZIP.

Is it safe to upload TIFF files to ConvertPixels?

Yes. Uploads use an encrypted connection and are processed automatically - nobody views them. Your originals are deleted straight after conversion and the results within an hour, or instantly if you click "Delete from server now".

TIFF to PPM / PNM

Why convert TIFF to PPM?

TIFF and PPM are both lossless formats. PPM is the usual choice for simple uncompressed images for scientific and developer tools. TIFF can have a transparent background, PPM can't.

Where PPM works best

PPM is ideal for simple uncompressed images for scientific and developer tools. Converting gives you a file that works in the apps and websites that ask for PPM.

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

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

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

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
