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, browser-based conversion from Hasselblad 3FR raw files to MNG animation-ready sequences for web workflows.

Lossless / Fast Conversion

Efficient decoding of 3FR raw frames and swift encoding to MNG animation streams in the browser.

High-Fidelity Output

Preserves full raster detail when rendering 3FR sensor data to 8- or 16-bit per-channel frames for MNG.

Batch Ready

Process multiple 3FR sequences into a single MNG stream or multiple MNGs in one session.

Web Publishing Focus

Targets web animation workflows: MNG suited for animated image delivery to compatible viewers and archives.

Client-Side Processing

All decoding and MNG assembly occur in-browser memory buffers without server upload by default.

Adjustable Encoding

Choose frame rate, loop behavior, and per-frame compression settings before exporting MNG.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR for Sequencing

Inspect 3FR exposure and apply consistent white balance before sequencing for uniform MNG frames
Demosaic 3FR using your preferred RAW engine to control highlight rolloff prior to MNG encoding
Strip unnecessary proprietary Hasselblad sidecar tags if they conflict with downstream metadata workflows
Rename frames into chronological order so MNG frame sequence preserves intended playback timing
Embed a consistent ICC when rasterizing 3FR frames so color stays predictable across MNG frames

Encode MNG Efficiently

Choose 8-bit frames when browser playback matters to reduce MNG size while accepting reduced headroom
Use PNG compression level tuning per frame to balance file size and CPU time during MNG assembly
Prefer repeating frame deltas only when supported by your encoder to shrink multi-frame MNGs
Limit frame rate to necessary playback speed to minimize total MNG bytes for web delivery
Store critical EXIF or capture timestamps in a sidecar if full in-MNG metadata embedding is uncertain

Validate Post-Conversion

Open exported MNG in ImageMagick or a specialized MNG viewer to inspect per-frame color and alpha
Check that embedded ICC or rendered color matches the original 3FR preview in your RAW editor
Compare histograms of source 3FR and MNG frames to detect unintended clipping after conversion
Verify timestamps and sequence order when frames derive from burst captures or timelapse shoots
Test playback on target platforms and fallbacks to ensure viewers properly loop and respect frame delays

Web Delivery Constraints

Assume limited native MNG browser support; plan WebM/MP4 fallbacks for mainstream viewers
Keep master MNG as high-quality archival output and generate optimized web variants for serving
Avoid very long MNG sequences; split into smaller segments for progressive loading on web pages
Securely handle source 3FR originals locally and export only the derived MNG to CDN when ready
Monitor memory when building large MNGs in-browser; export smaller chunks to sidestep browser limits

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.
