Mobile photographers converting RAW DNG captures from smartphones to shareable PNG formats.
Archiving digital negatives into a widely compatible, lossless compressed format with custom color adjustments.

Examples

1. Converting Smartphone DNG to Vivid PNG

Mobile Photographer
Background
A mobile photographer shot a sunset in RAW DNG format on their smartphone. The raw image looks slightly flat and needs a boost in color saturation before sharing.
Problem
Convert the DNG file to PNG while increasing color saturation and brightness to make the sunset colors pop.
How to Use
Upload the DNG file, set the Saturation slider to 1.3, set Brightness to 1.1, and leave the compression level at the default 6.
Outcome
A vibrant, high-quality PNG image ready for social media sharing with enhanced colors.

2. Resizing and Recovering Highlights from a DSLR DNG

Landscape Photographer
Background
A photographer has a high-resolution DNG landscape photo with slightly overexposed sky highlights that needs to be converted for a web preview.
Problem
Reduce the image size to a maximum width of 1920 pixels and recover details in the bright sky.
How to Use
Upload the DNG file, set the Output Width to 1920, and set Highlight Recovery to 5.
Outcome
A resized 1920px wide PNG file with recovered cloud details in the sky.

FAQ

Can I resize the image during conversion?

Yes, you can specify an optional maximum width and height in pixels to resize the output PNG.

What does the highlight recovery option do?

It helps restore details in overexposed or blown-out highlight areas of the RAW image.

How does the compression level affect the output?

A higher compression level (up to 9) produces smaller file sizes but takes longer to process, while 0 is the fastest with no compression.

Does this tool preserve image metadata?

Yes, the converter automatically extracts and preserves image dimensions and metadata from the original DNG file.

Is there a file size limit for the DNG upload?

Yes, the tool supports DNG RAW files up to 200 MB.
