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 high-fidelity Hasselblad 3FR raw images to DirectDraw Surface (DDS) for game engines and real-time renderers with predictable results.

Photographic Fidelity

Preserve raw Bayer-derived tonal range from 3FR by rendering into high-precision DDS formats for accurate shading.

Fast Local Conversion

Browser-side decoding and encoding avoid uploads, producing DDS tiles quickly for iterative game-asset workflows.

Engine Ready Output

Create commonly used DDS targets like BC1/BC3 and uncompressed RGBA to feed engines such as Unity and Unreal.

Efficient Batch Jobs

Process multi-shot 3FR sequences in groups to generate texture sets and mipmaps with predictable timing.

Control Over Encoding

Select target compression (BCn) and choose whether to generate mipmaps and target bit-depth for DDS outputs.

Client-Side Privacy

Files are decoded and encoded inside the browser session; media does not upload to external servers by default.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR Source Correctly

Demosaic 3FR using a linear or camera-referred profile to control highlight rolloff
Apply lens corrections and remove hot pixels before encoding to DDS to avoid artifacts
Export any exposure-blended HDR from 3FR stacks as a single image before DDS conversion
Flatten layered edits into a single RGBA raster if you need alpha baked into DDS
Generate a proof in the target color space because raw previews can differ from final DDS rendering

Choose Target DDS Encoding

Pick BC1 for opaque textures when file size matters but accept reduced color fidelity
Use BC3 or BC7 for alpha textures to balance transparency and compression artifacts
Select uncompressed RGBA32 or R16G16B16A16 for maximum tonal precision at larger sizes
Enable mipmap generation when targeting real-time engines to improve filtering and LOD
Test chosen DDS format in the engine pipeline to validate compressor tolerances

Verify Color and Metadata

Map 3FR camera profile to sRGB or linear space explicitly to avoid unexpected shifts
If metadata is critical, export EXIF/XMP sidecars from 3FR and attach alongside the DDS
Compare histogram and highlight clipping between 3FR render and DDS output at 100%
Check that alpha or mask channels were preserved by inspecting the DDS alpha plane
Confirm that engine import settings (gamma, normal map decoding) match exported DDS layout

Optimize Batch & Privacy Workflow

Process batches of 20–50 3FR files to maintain browser memory headroom and consistent results
Keep raw originals offline and store converted DDS in asset repositories with version tags
Clear local temporary caches after large conversions to prevent residual data exposure
Close other memory-heavy applications during batch BCn compression to reduce CPU throttling
Validate a representative sample from each batch in the target engine before mass deployment

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.
