OpenAnyFile
Works
Viewing, inspecting and verifying. You get the image (or the embedded full-size preview, for camera RAW) rendered on screen. File details, exact byte size and the detected signature are always shown.
How to open a .dpx file
DPX files come from Film scanners, DI colour suites, and the usual advice — buy the software that made it — is rarely what you need just to look inside one. This page covers what the format is and how to open it in a browser tab.
What is a .dpx file?
Digital Picture Exchange is an image format developed by SMPTE, first appearing in 1994. It is normally produced by Film scanners, DI colour suites.
The SMPTE standard for digital cinema frames. Sequences store one DPX per frame, so a single minute of footage can be 1,440 separate files.

Open a .dpx file in your browser
OpenAnyFile routes .dpx to its TIFF/RAW decoder, which decodes the image (or the embedded full-size preview, for camera RAW) rendered on screen.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .dpx file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the TIFF/RAW decoder.
- Your DPX opens on its own viewer page: the image (or the embedded full-size preview, for camera RAW) rendered on screen.
- Use fullscreen for a closer look, or download the file back out unchanged. Nothing is transmitted anywhere — the parsing happens in your own browser process.
What you can and cannot do with it here
Does not work
Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
Your {ext} file stays on your device
The entire pipeline — detection, decoding, rendering — runs client-side. Your browser hands the bytes to a decoder compiled to WebAssembly, the result is drawn to the page, and that is the whole journey. No account is created, no file is stored, and no analytics event carries your filename. This is also why there is no size limit imposed by a server: the only ceiling is your own available memory.
Frequently asked questions about DPX files
Can I open a .dpx file without installing special software?
Yes. OpenAnyFile's TIFF/RAW decoder runs in your browser, so you can read a DPX file with nothing installed. You get the image (or the embedded full-size preview, for camera RAW) rendered on screen. For full editing you still need the original application — this is a viewer, not an editor.
How can I check a file really is a DPX file?
Look at the first bytes rather than the extension. A genuine DPX begins with 53 44 50 58 or 58 50 44 53. Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .dpx by mistake is easy to spot.
Is it safe to open a DPX file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.
What is a .dpx file, exactly?
Digital Picture Exchange — an image/x-dpx format created by SMPTE since 1994. The SMPTE standard for digital cinema frames. Sequences store one DPX per frame, so a single minute of footage can be 1,440 separate files.
Does the same viewer handle formats related to DPX?
Yes — the same engine also opens .arw, .cr2, .dng, so you can compare related files without switching tools.
