DNG is Adobe's open, standardised RAW container designed as a portable archival format. That is why users land on this page looking for a AVIF copy. If you have ended up with a DNG and need a AVIF, the mismatch is almost always about where the image is going next rather than the picture itself. Our server reads the DNG with ImageMagick, decodes each pixel, and re-writes it as a AVIF using defaults tuned for fidelity first and file size second. In practice DNG is Adobe's open, standardised RAW container designed as a portable archival format. On the other end, AVIF is the AV1-based next-gen image codec, extremely efficient with full HDR and alpha support.
Digital Negative (RAW)
Source formatDNG is Adobe's open RAW image format designed as a universal standard for camera raw data. It preserves full sensor data and extensive metadata, making it ideal for non-destructive photo editing.
AVIF Image
Target formatAVIF is a next-generation image format based on the AV1 video codec. It offers significantly better compression than JPEG and WebP while maintaining excellent visual quality, including HDR and wide color gamut support.
Why convert DNG to AVIF
Both DNG and AVIF describe a grid of pixels — the difference lies in how that grid is compressed, whether transparency is supported, and which software opens it natively. Moving from DNG to AVIF is worth it when the AVIF ecosystem is broader for your use case, or when AVIF compresses photographs more efficiently than DNG.
HOW TO CONVERT
DNG → AVIF
Drop the DNG file
Drag and drop or click to upload your DNG. The image is transferred securely over HTTPS and queued for conversion.
Re-encode with ImageMagick
ImageMagick decodes every pixel of the DNG and writes a matching AVIF with sensible default quality settings.
Download the AVIF
The converted AVIF is ready to download as a single file; both files delete automatically within two hours.
Common Use Cases
Web publishing and CMSes
AVIF uploads cleanly to WordPress, Ghost, Webflow and most blogging platforms; many CMSes silently transcode or reject DNG.
Email attachments
Email clients preview AVIF inline while DNG may arrive as an unrecognised attachment on older Outlook or mobile apps.
Social media uploads
Platforms like Instagram, X and Facebook accept AVIF natively; DNG is often rejected or silently converted with unpredictable results.
Design hand-off
Designers shipping assets to developers prefer AVIF for faster pipeline imports and consistent display across build tools.
DNG vs AVIF — Strengths and limitations
What each format does best, and where it falls short.
DNG Strengths
- Open, documented standard (ISO 12234-2) — future-proof for archival.
- Based on TIFF — broad tool support beyond Adobe.
- Can embed the original proprietary raw as a safety copy.
- Smaller than most proprietary raws thanks to lossless compression.
- Stores every Adobe Camera Raw adjustment inline, so edits travel with the file.
Limitations
- Canon, Nikon, Sony, Fuji still refuse to adopt it.
- Some manufacturer-specific features (Fuji film simulations, Nikon Picture Control) are lost in conversion.
- Slower workflow — RAW from camera must go through DNG Converter first.
AVIF Strengths
- Best-in-class compression efficiency — 30-50% smaller than JPEG for the same quality.
- Royalty-free and patent-unencumbered (unlike HEIC).
- Supports alpha transparency, HDR, wide gamut (BT.2020), and up to 12-bit color.
- Progressive decoding: a blurry preview appears while the file is still downloading.
- Supported in all major browsers since late 2022 — no polyfills needed.
Limitations
- Encoding is CPU-expensive — an AVIF export can take 10-30× longer than JPEG.
- Older software (pre-2022) cannot open AVIF without plugins.
- Email clients still largely ignore it — stick to JPEG for attachments.

Quality & Compatibility
If AVIF is a lossless format (PNG, TIFF, BMP) the output keeps every pixel of the decoded DNG exactly. If AVIF is a lossy codec (JPEG, WebP, HEIC), the encoder re-compresses the image at the quality level you select — default 85 is transparent for photographs, quality 92+ for illustrations with hard edges.
Tips for Best Results
- Keep the original DNG alongside the AVIF output — re-encoding already-lossy images accumulates detail loss on each round.
- If the AVIF will be uploaded to a CMS, check whether the platform has a max dimension and downscale once on export rather than letting the CMS resize automatically.
- For thumbnails and avatars, export the AVIF at exactly the display size; browsers will otherwise resample and the image may look soft.
Frequently Asked Questions
Frequently Asked Questions
It depends on the codecs involved. If both DNG and AVIF are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If AVIF is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded DNG exactly, but cannot recover detail that DNG had already compressed away.
Often yes, especially when AVIF is lossless. DNG tuned for efficient web delivery will usually produce smaller files than AVIF's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
