Most people convert PNM to Sun Raster for compatibility — a website, app or device insists on Sun Raster, and PNM simply won't open. Sun Raster is widely supported, which makes it a dependable target. Under the hood the conversion runs on libvips and ImageMagick — the same libraries that power image pipelines across the web — so colour, transparency and metadata are handled correctly wherever the target format supports them.
It comes up when publishing online, submitting to a service with strict format rules, or archiving a collection in a single consistent format.
Privacy is the default here. Your PNM file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
