toolkit Drop as many DNG files as you like above to convert them to lossless PNG right here, in this browser tab, with the batch handed back as one .zip. Decoding runs entirely on your own device and nothing is uploaded, which matters when the raw file is a client's rather than yours. Apple ProRAW is DNG as well and is handled the same way.
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.
Batches, and the size they add up to
Any number of files can be added at once, free. Keep an eye on the total, though: a PNG from a raw file is lossless and therefore very large, so a batch of them adds up faster than any other conversion here. Results are held in this browser tab until you save them, and once enough unsaved output has accumulated the queue pauses rather than discarding anything. Saving the collected .zip releases it and the remaining files carry on.
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.
Can I convert several DNGs at once?
Yes, and there is no limit on the count. Because PNG output is so much larger than the DNG it came from, a long batch may pause partway and ask you to save what is finished — nothing is thrown away, and saving the .zip lets the rest continue.
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.
