DIRECT IMAGE CONVERTER:
HEIF to DNG Converter
Convert one still HEIF image to DNG using temporary server processing. Single still image, up to 2,073,600 pixels. Animation and multipage files are refused. Temporary server processing; files are deleted after the request. This route exports an 8-bit rendered composite; source bit depth, metadata and editable layers are not retained. HDR values outside 0–1 are clipped for the SDR intermediate. Fixed server encoding profile; quality and compression are not adjustable on this route. Linear RGB DNG from rendered pixels, not Bayer sensor data or a proprietary camera RAW file. Both dimensions must be at least 64 pixels. Transparency is composited onto white where the destination cannot retain alpha.
Convert online. Choose HEIF files, keep the output locked to DNG, then the temporary server engine processes the file for download without storing it.

Select your HEIF file when the browser app loads. This route uses the temporary server engine; request files are deleted after success, error, timeout, disconnect or coordinated shutdown.
What changes when converting HEIF to DNG
Input format details: HEIF is associated with Apple/iPhone image workflows and often needs conversion for Windows, Android or upload forms.
Output format details: DNG is part of camera RAW workflows, so conversion normally needs decoding, color processing and tone mapping before export.
Source input: HEIF input: High efficiency Apple image family conversion. HEIF: Uses a local HEIC decoder in your browser on browser-local routes, keeping source bytes on the device. Ready server routes, including still GIF/APNG exports, upload the file to temporary request storage. Only route-specific supported variants are accepted; guide-only pairs have no upload.
Target output: DNG output: Leica M8 camera CFA DNG input has four named server exports: JPG, JPEG, PNG and WEBP. Leica M8 only, uncompressed 8-bit CFA camera DNG. Temporary isolated LibRaw server processing, up to 64 MiB per file and 24 MP, with no embedded JPEG fallback. Rendered LinearRaw DNG, ordinary TIFF, other models and unsupported variants are refused as camera input; the existing rendered LinearRaw output writer remains separate.
This page focuses on the exact HEIF to DNG task: compatibility, compression, transparency, animation, metadata, color profile and output-quality trade-offs for this pair.
Transparency and layers
- Single still image, up to 2,073,600 pixels. Animation and multipage files are refused. Temporary server processing; files are deleted after the request. This route exports an 8-bit rendered composite; source bit depth, metadata and editable layers are not retained. HDR values outside 0–1 are clipped for the SDR intermediate. Fixed server encoding profile; quality and compression are not adjustable on this route. Linear RGB DNG from rendered pixels, not Bayer sensor data or a proprietary camera RAW file. Both dimensions must be at least 64 pixels. Transparency is composited onto white where the destination cannot retain alpha.
Best use cases for HEIF to DNG
- Create a rendered DNG copy while keeping the original HEIF unchanged.
- Prepare a single-image file for software that reads DNG.

Quality, file size and compatibility
DNG output should be chosen for the actual destination: web pages need small files, archives need predictable compatibility, design handoff may need transparency, and camera workflows may need color accuracy. ImageConvert separates available routes from guide-only routes so visitors do not get mislabeled downloads or silent animation/layer loss.
For lossy outputs such as JPG, JPEG, JFIF and many WEBP settings, quality can reduce file size but permanently changes pixels. For lossless or alpha-friendly outputs such as PNG and some WEBP settings, transparency and sharp graphics can be preserved when the source data supports it. Professional formats require explicit color management and metadata handling.
How to convert HEIF to DNG
- Choose HEIF files on this direct converter page.
- Keep the output locked to DNG and adjust quality when available.
- Convert with the temporary server engine; request files are deleted after success, error, timeout, disconnect or coordinated shutdown.
- Download the generated DNG copy and keep the original HEIF file untouched.
FAQ
Is HEIF to DNG available now?
Yes. This route uses a temp server engine; request files are deleted after success, error, timeout, disconnect or coordinated shutdown.
What changes when I convert HEIF to DNG?

Both dimensions must be at least 64 pixels. Transparency is composited onto white where the destination cannot retain alpha.
Will HEIF to DNG keep transparency, animation or layers?
It depends on the source and target. DNG output follows DNG format limits, so transparency, animation, editable layers, metadata and color profiles must be handled explicitly by the conversion engine.
Can I keep the original HEIF file after converting to DNG?
Yes. ImageConvert is designed to create a new DNG output and leave the original HEIF file unchanged.
