This website will open, on the client side, pretty much any file you throw at it.

658 file formats are supported: every raw camera format, obscure video/audio codecs, 3D files, virtualized images, IC designs, Photoshop/Coreldraw/AutoCAD designs and much more.

You can also export most of them to common formats: PNG for images, MP4 for videos, CSV for data, etc. You can trim video and audio files when you export them.

There’s around 140 MB of WASM decoders that are loaded dynamically, keeping the website fast and snappy.
