Quick answer: To convert BMP to PPM, add the BMP file to the iHateFiles BMP 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. BMP carries transparency and PPM cannot, so transparent areas are filled with a background colour you choose.
Should you convert BMP to PPM?
Do this when the image is going somewhere that will not accept BMP, and you are content to fix the background colour permanently.
Nothing is discarded
BMP 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 BMP 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.

What usually goes wrong
About the BMP. The file size surprises people. There is no compression to speak of, so the size depends only on the dimensions, not on how complicated the image is.
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 BMP to PPM
- Add your BMP file. It is read from your disk and stays there.
- Check the settings. The output format is already set to PPM.
- Press convert and the PPM file is saved back to your device.
Questions
How do I convert BMP to PPM?
Open this page, add your BMP 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 BMP 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 BMP files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
