Need help?How to Convert DNG to HEIF Online
- Upload Your DNG Files: Drag and drop or click "Add Files" to select Adobe Digital Negative RAW files from your computer — Lightroom exports, Pixel / Galaxy phone RAW captures, or DNGs from camera-vendor RAW converters. Batch is supported, so a whole shoot folder can convert in one pass.
- Pick a Quality Preset: Default is Very High (Recommended). Choose Highest if you want HEIF copies that hold up to detailed inspection, High for everyday phone / iPad viewing, Medium / Low for the smallest files when you just need lightweight previews. You can also set a target percentage of original or an exact file size in KB / MB.
- Resize and Set DPI (Optional): Pick a Resolution Preset (4K, 1440P, 1080P, 720P, down to 360P), scale by percentage, or enter custom width and height — handy for shrinking 45 MP DNGs to a phone-friendly 12 MP. DPI presets (72, 96, 150, 200, 300, 600, 1200) and Compression Speed control encode time vs final size.
- Convert and Download: Click Convert. Files process in your browser session and download individually or as a ZIP — no sign-up, no watermark, originals stay on your machine.
Why Convert DNG to HEIF?
DNG (Digital Negative) is Adobe's open RAW format, introduced in 2004 and built on the TIFF/EP standard. A DNG holds the unprocessed sensor data — typically 12 to 16 bit — so photographers can re-tune exposure, white balance, and color long after the shutter clicks. The trade-off is size: a single DNG from a modern phone or mirrorless camera runs 20-50 MB, and a day's shoot can fill several gigabytes. HEIF (High Efficiency Image Format), standardized by MPEG in 2013 and adopted by Apple in iOS 11 (2017), uses HEVC compression to deliver roughly half the size of JPEG at equal quality, with optional 10-bit color and image-sequence support. Common reasons to convert DNG to HEIF:
- Shrink RAW shoots for iCloud Photos — A 30 MB DNG becomes a 2-3 MB HEIF at Very High quality. A 500-photo wedding shoot drops from ~15 GB to ~1.5 GB, fitting comfortably in iCloud's 50 GB plan instead of forcing the 200 GB tier.
- Browse RAW captures on iPhone and iPad — iOS opens HEIF natively in Photos; DNG requires a third-party RAW viewer and stutters on large files. Converting your edited keepers to HEIF lets you swipe through them at full speed alongside regular phone photos.
- AirDrop and iMessage edited shots — DNGs are often too large to AirDrop quickly and get re-compressed badly when sent through iMessage. HEIFs transfer in seconds and preserve the look you intended.
- Free up Mac and iPhone storage — A photographer's archive of 5,000 DNGs at 25 MB each is 125 GB. The HEIF equivalent at Very High preset lands closer to 12 GB — a 10× reduction without visible loss for non-editing use.
- Modernize Pixel and Galaxy DNG captures — Google Pixel and Samsung phones save RAW as DNG. Converting those to HEIF aligns them with the rest of your iOS / macOS photo library and saves space on cross-platform devices.
- Send proofs to clients on Apple devices — Clients on iPhone or iPad see HEIF previews instantly; sending DNGs forces them to install a viewer. Use HEIF for proofs and keep DNGs as your editable masters.
DNG vs HEIF — Format Comparison

| File size (24 MP photo) | 20-40 MB | 2-4 MB |
| Bit depth | 12-16 bit per channel | 8 or 10 bit per channel |
| Editing flexibility | Full RAW control (exposure, WB, highlights) | Limited — image is already developed |
| Native viewer | Lightroom, Camera Raw, RawTherapee, darktable | iOS, iPadOS, macOS, Windows 10+ (with HEIF extension), Android 10+ |
| Year introduced | 2004 (Adobe) | 2013 spec / 2017 Apple adoption |

HEIF Quality Preset Quick Guide
| Preset | Visual quality | Size vs DNG | Best for |
|---|---|---|---|
| Highest | Visually identical at 100% zoom | ~10-15% of DNG | HEIF copies you may revisit closely |
| Very High (default) | Indistinguishable for normal viewing | ~7-10% of DNG | Phone / tablet libraries, iCloud uploads |
| High | Indistinguishable at typical viewing distance | ~5-7% of DNG | Shareable proofs, AirDrop to clients |
| Medium | Minor softening on close inspection | ~3-5% of DNG | Casual sharing, social posts |
| Low / Lowest | Visible compression on detailed images | ~1-2% of DNG | Tiny previews, contact sheets |
Frequently Asked Questions
Will I lose RAW editing flexibility by converting to HEIF?
Yes — that is the fundamental trade-off. DNG carries the unprocessed sensor data so you can re-tune exposure, white balance, and highlight recovery in Lightroom or Camera Raw. HEIF stores a developed image: the conversion bakes in your current settings. The professional workflow is to keep the DNG masters in cold storage (NAS or external drive) and convert HEIF copies for viewing, sharing, and mobile devices. If you ever need to re-edit, go back to the DNG.
Is HEIF the same as HEIC?
Almost. HEIF is the container format standardized by MPEG; HEIC is Apple's specific filename for HEIF using HEVC compression. The byte content is the same in most cases — iOS, macOS, and Windows treat them identically. We expose both targets so you can pick the extension your downstream tool expects. If you specifically need the .heic extension (Apple Photos, AirDrop), use DNG to HEIC instead.
Will my HEIF files open on Windows or Android?
Windows 10 and 11 support HEIF after installing the free HEIF Image Extension from the Microsoft Store. macOS, iOS, and iPadOS open HEIF natively. Modern Android (10+) handles HEIF in the Photos / Gallery apps. Older Windows 7 / 8 systems and many Linux desktops still need a third-party viewer or codec. If your audience is mixed-platform, consider DNG to JPG instead for universal compatibility.
How much smaller will my HEIFs actually be?
For typical 24-50 MP DNGs, expect roughly 90% reduction at Very High preset. A 30 MB Pixel or Lightroom DNG lands around 2-3 MB as HEIF. Highly detailed scenes (foliage, fine fabric, busy backgrounds) compress slightly less; flat areas like sky or studio backdrops compress more. Choosing Highest preset roughly doubles file size compared to Very High but is closer to lossless visually.
Does conversion preserve EXIF, GPS, and color profile?
Yes. EXIF metadata (camera model, lens, aperture, shutter, ISO, capture date, GPS) and embedded ICC color profiles transfer to the HEIF output. iPhone Photos and macOS Preview will read the right capture date so the photos slot into the correct chronological place in your library, and the color profile keeps tones consistent on Wide-Gamut displays.
What about 16-bit color depth — does HEIF preserve it?
HEIF tops out at 10 bits per channel (HEVC Main 10 profile), versus DNG's 12-16 bits. For viewing on phones and tablets the difference is invisible. For master archives where you may push tones aggressively in future edits, keep the DNG. The HEIF is a delivery format, not a master format.
Can I batch convert an entire RAW shoot?
Yes — drop in folder-fulls. Each DNG converts in parallel in your browser session (limited only by your CPU and memory) and downloads as a ZIP. For multi-gigabyte shoots, processing is browser-side so there's no upload bottleneck — the limit is your machine's RAM, not network bandwidth.
Will the HEIFs import cleanly into Apple Photos and iCloud?
Yes. Drop the converted HEIFs into Photos on Mac or import via the Photos app on iPhone / iPad and they appear as native HEIF images. Date-taken EXIF determines their slot in the timeline, so older DNGs land in the correct chronological place. Once they sync to iCloud, they show up at full resolution on every device signed into the same Apple ID.
Should I keep my DNG originals after converting?
Yes. HEIF is a one-way trip in editing terms — you cannot recover RAW headroom from a developed HEIF. Treat HEIF as a delivery / viewing format and DNG as the master archive. Cold-store the DNGs (external drive, NAS, cloud archive) and use HEIF copies for daily viewing and sharing.
