Free online PNG→OpenEXR converter. Fast, private, no sign-up.
Converting PNG to OpenEXR is one of those small tasks that should be instant and free — and here it is. Drop in your PNG file (a .png) and download a ready-to-use OpenEXR file (a .exr) — no software to install, no account to create, and no watermark on the output.
PNG is a lossless format that preserves every pixel and supports full alpha transparency — the standard for logos, icons, screenshots and any graphic with crisp edges or text. The trade-off is larger files than lossy formats for photographs.
OpenEXR 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.
Most people convert PNG to OpenEXR for compatibility — a website, app or device insists on OpenEXR, and PNG simply won't open. OpenEXR 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.
OpenEXR has no alpha channel, so any transparent areas in your PNG are flattened onto a solid background during conversion.
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 PNG 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.
