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?

Convert Hasselblad 3FR raw images to HEIF efficiently while balancing image quality and archive size

High-Fidelity Rendering

Accurate demosaicing and color mapping from 3FR raw sensor data to HEIF-ready RGB images.

Fast Local Conversion

Convert in-browser without uploads; optimized for single images and moderate batches.

Smaller HEIF Files

HEIF uses modern compression to reduce filesize compared with TIFF while retaining perceptual quality.

Broad Playback Support

Produce HEIF outputs compatible with modern macOS, iOS, and select Android and image viewers.

Client-Side Privacy

Files are processed in-browser memory buffers so media does not leave your device by default.

Custom Export Options

Adjust quality and subsampling to trade off compression versus retained fine detail.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR Raw

Confirm 3FR contains the expected CFA pattern and verify shutter/ISO EXIF before decode
Apply necessary exposure compensation in raw decode to prevent clipped highlights in HEIF
If your 3FR includes proprietary Hasselblad tags, export sidecar XMP to preserve specialized metadata
Convert tied 3FR white balance to a standard profile to reduce color shifts during HEIF encoding
Downsample extremely large 3FR masters only after confirming retained detail meets print or delivery needs

Choose HEIF Encoding

Select 4:4:4 chroma when you need to preserve fine color transitions from the 3FR demosaic
Use higher quality / lower quantization for archival HEIF when preserving tonal gradients is required
Prefer HEVC intra-frame profiles that support ICC embedding if downstream color management is needed
Avoid aggressive subsampling for images with color edges, such as foliage or textiles from 3FR captures
Set target bit-depth deliberately; exporting at a higher depth reduces banding at the cost of filesize

Integrate with Software

Test HEIF output in your target editor (Photos, Lightroom) to ensure expected import color handling
For client delivery, verify HEIF opens on intended devices to avoid playback or codec issues
When using Capture One or Lightroom for edits, keep the original 3FR for re-editing fidelity
If your pipeline requires TIFF for compositing, convert 3FR to high-quality TIFF instead of HEIF
Automate batch checks to flag HEIFs that differ significantly in histogram from source 3FR

Verify and Optimize Output

Inspect final HEIF at 100% to confirm sharpness and demosaic artifacts have not been introduced
Compare EXIF focal length and orientation fields between 3FR and HEIF to ensure consistency
Use a color-managed viewer to validate ICC profile application after conversion
If visible banding appears, re-export with higher bit depth or reduced compression
Keep original 3FR archives until delivery acceptance to allow reprocessing if conversions need adjustment

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.
