Free online PGM→HEIC converter. Fast, private, no sign-up.
Going from PGM to HEIC takes a couple of clicks: drop the file in, download the result. Drop in your PGM file (a .pgm) and download a ready-to-use HEIC file (a .heic) — no software to install, no account to create, and no watermark on the output.
PGM is an image format. Converting to or from it lets you use the same picture in apps and on platforms that expect a different format.
HEIC is what iPhones shoot by default: modern, efficient, roughly half the size of JPEG at the same quality. The downside is patchy support outside Apple devices, which is why converting it is so common.
Most people convert PGM to HEIC for compatibility — a website, app or device insists on HEIC, and PGM simply won't open. HEIC 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.
Because PGM is uncompressed, the HEIC you get back will typically be dramatically smaller. Unlike PGM, HEIC supports transparency, so it's a good target if you later need a cut-out.
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 PGM 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.
