How do I convert a PNG file to DNG online?

Use the LetsConvert PNG to DNG tool: upload your PNG file, choose DNG as the target format, and press Convert. The file is processed in your browser and you can download the resulting DNG seconds later. No installation or account needed—just a direct, lossless conversion.

What is the difference between PNG and DNG, and why convert?

PNG is a lossless bitmap format optimized for screens—it uses deflate compression and supports transparency, but stores pixels in an 8-bit indexed or RGB format. DNG, however, is Adobe's open raw format that stores sensor data in a 16-bit linear container, enabling non-destructive editing in raw processors like Lightroom, Camera Raw, and Capture One. Converting PNG to DNG adds raw-level flexibility, higher bit depth, and allows you to apply white-balance and exposure adjustments without permanently altering the original image.

How are transparency, color profiles, and resolution preserved in PNG to DNG conversion?

DNG supports alpha channels, so PNG's transparent areas are retained as an alpha mask. Embedded ICC profiles from the PNG are carried over, ensuring consistent color on wide-gamut displays. Resolution and pixel dimensions are untouched—the conversion repackages the pixel data into a 16-bit raw container, which slightly increases file size but preserves all visual information. Metadata such as EXIF and XMP, if present, is also transferred.
