What is a DPX file?
A .DPX file is a Digital Picture Exchange File. It is a raster image format used to store a single frame of a digital motion picture. The SMPTE (Society of Motion Picture and Television Engineers) created this standard. Film scanners, visual effects programs, and color grading software use .DPX files to hold uncompressed, high-quality image data. A single video clip is usually saved as a sequence of thousands of .DPX files.
Are there other DPX formats?
Yes. While most .DPX files are cinema frames, the extension has multiple possible meanings. It can be an HMI project design file for M2I XDesignerPlus, a drawing template for Serif DrawPlus, a D-Pixed image, or a security file for VASCO DIGIPASS. Because of this variety, viewer.online/dpx analyzes .DPX files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
How to open DPX files?
Professional video editing software manages cinematic .DPX sequences. You can open them on a desktop computer using DaVinci Resolve, Adobe Media Encoder, or Adobe After Effects. If you only want to view a single frame, command-line tools like FFmpeg or image viewers like XnView can read the format.
File conversion
If you need to share a .DPX frame with someone who lacks professional cinema software, you should convert the file. We recommend using convert.guru to convert .DPX to standard .JPG or .PNG formats. You can also convert a full folder of .DPX image sequences into a playable .MP4 video.
Summary
viewer.online/dpx directly opens and previews .DPX files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
