Drop PNG files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.
Save the PPM, or download everything as one ZIP if you converted several files.
The PNG to PPM converter is part of this page and runs inside your browser. Your images are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
PNG files are large, especially for photographs. PPM is the simplest image format there is, readable by any programming language. PNG is at home in screenshots, logos, graphics with text or transparency; PPM is the usual choice for passing images between command-line tools.
PPM has no transparency, so see-through areas of a PNG are filled with a solid colour, white by default; you can change it under Options. The defaults suit most files. Under Options you can resize the result.
PPM stores three bytes per pixel with no compression, so files are large.
PNG stores every pixel exactly, with optional transparency. It was created as a patent-free replacement for GIF and is the standard for screenshots, logos and interface graphics. Photos saved as PNG are several times larger than the same photo as JPG.

PNG converterPPM is the colour member of the Netpbm family: a short text header followed by the raw red, green and blue values of every pixel. It does no compression at all, which makes it trivial to write and read in any language and a favourite in teaching and in scripts. PNM is the collective name for PBM, PGM and PPM.

No. The PNG to PPM conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
No further quality is lost: PPM stores the decoded pixels exactly. The result is identical in content.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the PNG file, press Convert and save the PPM. There is nothing to install.
Pictures of up to 120 megapixels are accepted (for example 12,000 by 10,000 pixels); a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
