toolkit Drop a DNG file below to convert it to PNG right here, in this browser tab. Decoding runs entirely on your device — the file is never uploaded.
Why PNG instead of JPG
PNG is lossless, so nothing further is discarded once the DNG's raw data has been decoded into pixels. It's the right choice if you want to avoid JPEG compression artifacts, or need the result for further editing rather than final delivery.
What DNG is
DNG (Digital Negative) is Adobe's openly published raw image format, used both as a raw format some cameras save directly and as the container behind Apple's ProRAW mode on iPhone.
Orientation is preserved
The DNG's orientation tag is read and applied before the pixels are returned, so the PNG comes out the right way up without a separate rotation step.
File size expectations
PNG's lossless compression produces a noticeably larger file than an equivalent JPEG, especially for detailed photographic images. If file size matters more than lossless fidelity, DNG to JPG is usually the better fit.
Frequently asked questions
Is my photo uploaded anywhere?
No. Everything runs locally in your browser via WebAssembly; the DNG file never leaves your device.
Does this handle Apple ProRAW DNG files too?
Yes — Apple ProRAW files are DNG files, decoded the same way as any other DNG.
Will orientation be correct?
Yes — the DNG orientation tag is read and applied automatically before conversion.
Why is the PNG much bigger than the DNG?
DNG stores compressed raw sensor data; PNG stores a fully decoded, lossless bitmap. That size increase is expected.
Can I convert a PNG back into DNG?
No. DNG decoding is one-way here — there's no encoder that writes DNG files.
