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 conversion from Hasselblad 3FR raw images to Windows ICO icons for device sharing and app resources.

Raw to Icon Fast

Convert 3FR raw captures into ICO icons quickly for desktop and app use without heavy tooling.

Controlled Rasterization

Render 3FR Bayer-mosaic raw data to raster bitmaps with adjustable resizing and sharpening before ICO packing.

Windows & App Friendly

Produce ICO files compatible with Windows explorer, shortcuts, and many legacy app icon loaders.

Batch Icon Packs

Process multiple 3FR files into multi-resolution ICOs, producing icon sets for varied DPI targets.

Local Browser Processing

Conversion runs in-browser memory buffers; source 3FR files need not leave your device during processing.

Export Control

Choose target sizes and whether to include alpha channel where ICO and the selected resolution permit.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare Raw Exposure

Demosaic 3FR in a RAW editor to correct white balance before packing into ICO
Apply highlight recovery in 3FR to avoid clipped highlights in small icon sizes
Crop to icon-centric composition in the 3FR editor so details remain readable at 16–48 px
Export a flattened high-resolution bitmap from 3FR to control sharpening for small targets
Save a sidecar with EXIF from 3FR if camera metadata must be preserved separately

Target Encoding Choices

Select PNG-encoded ICO entries to retain 8-bit alpha from your processed 3FR image
Avoid BMP-style ICO entries if minimizing filesize for distribution is a priority
Include only necessary resolutions (e.g., 16, 32, 256) to balance compatibility and size
Downsample 3FR color depth intentionally to reduce posterization in small icons
Use lossless PNG compression for critical icons to avoid additional compression artifacts

Verify Across Platforms

Preview ICO output on the target Windows versions to check scaling and alpha rendering
Test icons inside application resource loaders and browser favicons where applicable
Compare the 3FR-derived icon against the original 3FR at 100% to ensure legibility
Confirm that sRGB rendering matches expected color when source 3FR was shot in a different profile
Check that transparency edges are clean after conversion and do not show haloing

Workflow Reliability

Process 3FR batches in groups of 20–50 to reduce in-browser memory pressure during ICO packing
Keep originals on stable storage before converting since ICO output is flattened and irreversible
Close other heavy tabs to free memory for large 3FR demosaicing tasks in the browser
Export a high-resolution intermediate if multiple icon sizes require different sharpening settings
Download converted ICO sets promptly and archive originals plus any EXIF sidecars

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.
