What file formats do you support?

We support over 100 file formats including images (JPG, PNG, GIF, WebP, TIFF), documents (PDF, DOC, DOCX, TXT), videos (MP4, AVI, MOV), audio (MP3, WAV, FLAC), and many more specialized formats.

Yes, absolutely. We use enterprise-grade encryption for all file transfers. Your files are automatically deleted from our servers after conversion, and we never store or access your personal data.

What is the maximum file size?

The maximum file size for free users is 100MB per file. Premium users can convert files up to 1GB. For larger files, we recommend our batch processing feature.

How long does conversion take?

Most files convert in under 30 seconds. The exact time depends on file size and format complexity. Our advanced algorithms ensure the fastest possible conversion while maintaining quality.

Can I convert multiple files at once?

Yes! Our batch processing feature allows you to upload and convert up to 50 files simultaneously. This is perfect for bulk conversions and saves significant time.

Do I need to create an account?

No account is required for basic conversions. However, creating a free account gives you access to batch processing, file history, and priority support.

Why Choose Our Converter?

Fast, reliable DNG to HEIC conversions balancing photographic fidelity and reduced storage for modern workflows.

Lossless / Fast Conversion

High-speed client-side conversion minimizes upload time while preserving as much raw data as feasible during rasterization.

Photographic Quality

Optimized HEIC encodes preserve tonal range and chroma fidelity better than standard JPEG for most DNG raws.

Batch Efficient

Process dozens of DNG files in one session to convert camera raws into compact HEICs for mobile workflows.

Wide Compatibility

Produces HEIC files compatible with modern iOS, macOS and many imaging apps that support HEIF containers.

Adjustable Output

Choose quality trade-offs; higher HEIC compression reduces size but can alter fine shadow detail and noise texture.

Local Processing

Conversions run in-browser memory buffers when possible, limiting external transfers of original DNG photos.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare Raw DNG Correctly

Demosaic and apply white balance in a raw editor before export to maintain intended color rendering
Embed standard ICC profiles in the DNG or sidecar to improve profile mapping during HEIC encoding
Remove large embedded previews from DNG if you want the converter to use the primary raw rather than an outdated JPEG preview
Flatten paired DNG edits (XMP sidecar) into the rasterized image if you expect those adjustments reflected in HEIC
Confirm camera-specific linearization settings because converter demosaicing can differ from your raw developer

Choose HEIC Encoding Wisely

Select a lower HEVC quantizer for less compression to preserve midtone texture from DNG demosaicing
Enable 10-bit HEIC when available to reduce banding compared to 8-bit outputs from high-contrast DNGs
Trade file size for retained shadow detail by adjusting HEIC quality rather than resizing dimensions
Embed ICC profile into HEIC to keep color intent across compatible viewers
If archival fidelity is required, keep original DNG files and use HEIC only for distribution

Platform and Workflow Checks

Test HEIC output on target devices; iOS/macOS handle HEIC natively, but many web CDNs may not
When integrating into a CMS, verify server-side image processors recognize HEIC or fallback to JPEG generation
For photo apps that expect 16-bit source, note that HEIC might reduce bit depth and affect further edits
If using cloud editors, confirm they accept HEIC containers with embedded ICC and EXIF data
Preview converted images in the final viewer to detect unintended clipping from tone mapping

Verify Metadata & Privacy

Check that crucial EXIF tags like orientation and GPS were mapped into HEIC before publishing
Strip sensitive EXIF fields if sharing publicly by removing them prior to conversion when required
Keep originals offline; HEIC is a delivery format, not a substitute for raw preservation
Ensure timestamps are consistent between DNG and HEIC to avoid asset management mismatches
For compliance, confirm that proprietary DNG maker notes were not required downstream and handle accordingly

Fast Processing

Close unused tabs for maximum throughput.

Client-Side Privacy

No media leaves your device.

Broad Compatibility

Output files work across all operating systems.

Pro Tip

For batch conversions, process in groups of 20-50 files to optimize memory usage and avoid browser slowdowns.
