DPX to PNG Converter

What happens when you convert DPX to PNG

• ImageMagick, the open-source image toolkit, reads the DPX on our conversion server and saves it as a lossless PNG.
• Transparent areas stay transparent.
• A DPX with more than 8 bits per channel, such as the usual 10-bit film scan, becomes a 16-bit PNG, so none of that detail is lost.
• A film scan stored in a logarithmic encoding comes out flat and grey, just as it looks before colour grading; the values are converted as they are.
• This conversion runs on our server: the file is uploaded, converted, and deleted together with the result as soon as the result has been sent back to you. Nothing is kept. Files up to 25 MB are accepted.

How to convert DPX to PNG online

1. Press "Choose DPX files" and select one or more files, or drag them onto the box. Files up to 25 MB each can be converted.
2. There are no settings to choose: the converter keeps everything the target format can hold.
3. Press "Convert to PNG". The file is uploaded to our conversion server, converted in a few seconds, and deleted together with the result as soon as the result is sent back.
4. Save each PNG with its download button. Our server has already deleted both your DPX and the PNG by then.

Why convert DPX to PNG?

DPX files usually come from film scanning, visual effects and digital cinema work. People convert them to PNG because PNG keeps sharp edges, text and transparency without any loss.

In short, DPX is good at what it was made for, and PNG is the more practical choice when the file has to open, upload or print somewhere else. DPX does not open in browsers; DaVinci Resolve, Nuke, After Effects and other film tools open it, while PNG opens in every browser and image viewer.

DPX vs PNG: the differences

About DPX and PNG files

What is a DPX file?

DPX holds a single frame per file, so a scanned film is a folder of thousands of numbered DPX files. Film scans are often stored in a logarithmic encoding that keeps the full range of the negative, which is why an ungraded DPX looks flat and grey.

What is a PNG file?

PNG compresses without losing a single pixel, so screenshots and text stay razor sharp, but a photograph saved as PNG is often three to five times the size of the same photo as JPG.

DPX to PNG not working? Common problems

• "Files up to 25 MB can be converted." Server conversions have a size limit. Save the image at a smaller size first.
• "The conversion took too long and was stopped." Very long or complex files can pass the 90 second limit. Split the file and convert the parts.
• "This file is not really in DPX format." The converter checks every file before it runs anything, so a file of another format renamed to .dpx is refused. Choose the page for its real format.

Convert DPX to PNG from the command line

ImageMagick does the same on your own computer:

magick input.dpx output.png

Converting on your own computer keeps the file entirely local, which is worth it for very large or very sensitive documents. For everything else, the converter on this page does it without installing anything.
