Supports: DNG
DNG (Digital Negative) is Adobe's open RAW format, introduced in 2004 to standardize RAW archival across vendors. It's the native RAW format on Leica M-series, Q-series, and SL bodies, Pentax K-series DSLRs, Hasselblad X-series and H-series, Sigma fp, and the RAW output of Google Pixel (Pixel 6/7/8/9 Pro), some Samsung Galaxy phones, and many drone cameras (DJI Mavic, Air, Mini Pro). Adobe's own DNG Converter ingests proprietary RAW (CR2, NEF, ARW, RAF, ORF) and emits DNG so you can keep a vendor-neutral master archive. JPG is the universal compressed image format — opens on every browser, OS, phone, and print kiosk on earth. Common reasons photographers convert DNG → JPG:
| Property | DNG (Digital Negative) | JPG |
|---|---|---|
| Compression | Lossless (or uncompressed) | Lossy (DCT) |
| Color depth | 12-bit, 14-bit, or 16-bit per channel | 8-bit per channel |
| Typical file size | 15-50 MB | 1-10 MB |
| Editing latitude | Wide — recover ±2 stops, full white balance freedom | Narrow — limited highlight/shadow recovery |
| Standard | Open (Adobe public spec, ISO 12234-2) | Open (JPEG / JFIF, ISO 10918) |
| Native viewer | Lightroom, Camera Raw, Capture One, RawTherapee, darktable | Every browser, OS, phone, print kiosk |
| Social media upload | Not accepted | Universal |
| EXIF / IPTC metadata | Full (camera, lens, GPS, edit history) | Preserved on conversion |
| Best for | Vendor-neutral RAW archive, future re-edits | Sharing, web, email, print delivery |
| Preset | JPG quality | Output size (from 35 MB DNG) | Best for |
|---|---|---|---|
| Highest | ~98% | 6-12 MB | Archival, large prints, hero images |
| Very High (default) | ~92% | 3-7 MB | Client delivery, portfolios, fine-art proofs |
| High | ~85% | 1.5-4 MB | Web galleries, blog posts, email |
| Medium | ~75% | 0.8-2 MB | Social media, contact sheets |
| Low | ~60% | 300-700 KB | Thumbnails, quick reviews |
| Very Low | ~40% | 80-300 KB | Email previews, mobile messaging |
Yes — EXIF and most IPTC metadata transfers from DNG to the JPG output. Camera body (Leica M11, Pixel 8 Pro, Hasselblad X2D 100C, Pentax K-3 III), lens model (Summilux 35mm f/1.4, Pixel computational lens, XCD 55V), shutter speed, aperture, ISO, focal length, and GPS coordinates all carry over. If you want to strip metadata before publishing online — common for protecting location privacy on home or studio shots — enable the "remove EXIF" option in advanced settings.
Yes — always. DNG holds 12-16 bits of color per channel and full sensor data; JPG is 8-bit and lossy. Once you discard the DNG, you can't recover blown highlights, fix white balance from scratch, or re-edit with new RAW software in 5 years. Standard workflow: keep DNG masters on backup drives or cloud (Backblaze, Carbonite, iDrive) and treat JPG as a delivery/share format only.
DNG is an open, documented format (Adobe published the spec; ISO standardized it as TIFF/EP and ISO 12234-2). Proprietary RAW formats are vendor-controlled and can be discontinued, change versions, or lose support — Canon shipped at least four CR2 / CR3 sub-variants over a decade. DNG is one format, one spec, future-proof. That's why Adobe's DNG Converter exists: convert proprietary RAW to DNG once, archive forever. See CR2 to DNG and NEF to DNG for that workflow; this page handles the opposite direction (DNG → JPG for delivery).
It depends. Pixel and Galaxy phones save a single linear DNG (one exposure, no HDR fusion), which is small (~12-20 MB) and lower bit depth than full-frame mirrorless. Color and detail are great for the sensor size but not equivalent to a Leica M11 or Pixel Pro multi-frame DNG. For phone DNG, "Very High" preset already produces a JPG that's visually indistinguishable from the source on a phone screen. Pro multi-frame computational DNG (Pixel "Pro RAW") benefits from "Highest" if you want to preserve every bit of the computational pipeline.
Yes — drop in 100, 500, or even 2,000+ DNG files. Each converts in parallel within your browser session and downloads as a ZIP. Useful for travel photographers prepping web galleries from a multi-week trip, drone operators converting aerial surveys, or wedding shooters delivering selects. Nothing uploads to a server, so even a 60 GB DNG folder stays private.
Same workflow applies for other camera makers. See CR2 to JPG for Canon EOS DSLRs, NEF to JPG for Nikon D / Z bodies, ARW to JPG for Sony Alpha, and RAF to JPG for Fujifilm X-series. The math is the same: RAW master → JPG delivery.
DNG stores raw 12-16 bit sensor data, often with lossless compression but no demosaicing — it's a digital negative. JPG stores a finished, demosaiced, 8-bit image with DCT-based lossy compression. A 35 MB DNG routinely becomes a 3-6 MB JPG at "Very High" — that's a 5-10× reduction with very little visible quality loss for normal viewing distances. This is normal and expected.
No — identical format. "JPEG" is the full name (Joint Photographic Experts Group); "JPG" is the legacy 3-character extension from DOS-era filesystem limits. Both are byte-for-byte compatible. See DNG to JPEG if you prefer the .jpeg extension.
No — JPG is a lossy format by design. The default "Very High (Recommended)" preset (~92% quality) produces output that is visually indistinguishable from the source for almost all viewing scenarios, but a pixel-peep comparison will show DCT artifacts. For a true lossless conversion of DNG, convert to DNG to TIFF or DNG to PNG instead.
