Can I convert AVIF to PPM without losing quality?

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

Does PPM keep the transparent background of my AVIF?

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 convert an animated AVIF to PPM?

PPM only stores still images, so you'll get the first frame. To keep the animation, convert to GIF or WebP instead.

Can I batch convert AVIF to PPM?

Yes. Add up to 30 AVIF 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 AVIF 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".

AVIF to PPM / PNM

Why convert AVIF to PPM?

The main difference: AVIF is a lossy or lossless format, while PPM is a lossless format. AVIF 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.

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

Property	AVIF	PPM / PNM
Compression type	Lossy or lossless	Lossless (exact pixels, larger files)
Transparent background	Yes	No
Animation	Yes	No
Where it opens	Chrome, Edge, Firefox and Safari 16+; many apps can't open it yet	None

What is an AVIF file?

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec, developed by the Alliance for Open Media - Google, Apple, Microsoft, Netflix and others. It typically produces smaller files than both JPG and WebP at the same visual quality.

AVIF supports transparency, HDR and wide color, which makes it a favorite for fast websites. Support outside browsers is still patchy, so downloaded AVIF files often need converting.

How to open an AVIF file

Chrome, Edge, Firefox and Safari 16+ display AVIF. Windows 11 opens it in Photos once the free AV1 Video Extension is installed; macOS Ventura and later preview it. For editors and forms that refuse it, convert to JPG or PNG.

Extension: .avif
Compression: Lossy or lossless (AV1)
Transparency: Yes
Best for: The smallest high-quality web images

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
