Quick answer: To convert APNG to PPM, add the APNG file to the iHateFiles APNG to PPM converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. APNG carries transparency and PPM cannot, so transparent areas are filled with a background colour you choose.
Should you convert APNG to PPM?
Do this when the image is going somewhere that will not accept APNG, and you are content to fix the background colour permanently.
Nothing is discarded
APNG and PPM are both lossless, so every pixel survives the move intact. Convert back and forth as often as you like; the image does not degrade.
PPM cannot hold transparency
Any transparent area in the APNG has to become a real colour, because PPM has no alpha channel to record it. The background colour on this page is what those areas become. White suits most uses; pick the colour of the page it will sit on if you know it, because this cannot be undone afterwards.
PPM holds one frame
An animated APNG becomes a single still PPM: the first frame, with the rest discarded. If you wanted the movement, convert to a format that keeps it instead.

What usually goes wrong
About the APNG. Converting a single still image to APNG just gives you a PNG, because there is nothing to animate.
About the PPM. The size is the whole trade. A 12 megapixel photo is 36 MB as PPM regardless of its content.
How to convert APNG to PPM
- Add your APNG file. It is read from your disk and stays there.

Questions
How do I convert APNG to PPM?
Open this page, add your APNG file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this APNG to PPM converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to PPM lose quality?
PPM is lossless, so this step throws nothing away. If the original was already a lossy format, the damage it did cannot be undone, but nothing further is lost.
Can I convert several APNG files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
