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 3FR to RAS conversion tailored for photographers and archival workflows, focused on device sharing and accessibility.

Fast Conversion Pipeline

Optimized client-side decoding of 3FR raw data to RAS with minimal latency for single-file jobs.

Preserve Image Fidelity

Renders 3FR sensor data into a high-resolution raster while avoiding additional lossy recompression steps.

Device Sharing Ready

Produces RAS files suitable for legacy viewers and remote systems that expect simple raster containers.

Local Client Processing

All decoding and rasterization occur in-browser memory buffers to protect original 3FR files from upload.

Batch-Friendly

Handle tens to hundreds of 3FR images in grouped jobs, optimizing memory and throughput per browser limits.

Deterministic Results

Consistent raster outputs from identical 3FR inputs; variations occur only with differing metadata or profiles.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR Sensor Data

Validate camera model and lens data inside 3FR to ensure correct demosaicing parameters are applied
Apply exposure or highlight recovery in your raw editor before rasterization if you need a specific tone curve embedded
If 3FR contains multiple embedded ICC matrices, choose the intended matrix to avoid color misinterpretation during raster output
Convert high ISO 3FRs with noise-reduction presets first to prevent baked-in noise artifacts in RAS deliverables
For bracketed captures, merge into a single HDR TIFF externally; the converter expects single-frame 3FR inputs

Target RAS Encoding Choices

Select the highest bit depth RAS variant supported by your viewer to retain dynamic range from 3FR
Be aware that exporting 16-bit RAS increases file size substantially compared to 8-bit output
If the consuming system lacks 16-bit support, downsample to 8-bit with a controlled gamma to avoid posterization
Embed an ICC profile during rasterization when the target application recognizes embedded profiles to preserve color fidelity
Compress RAS archives into ZIP for device sharing to reduce transfer size while keeping pixel data intact

Platform and Workflow Compatibility

Test RAS output on intended device viewers to confirm correct byte-order and endianness interpretation
When sending to CMS or remote viewers, include a small preview JPEG alongside RAS for fast thumbnails
If a target editor prefers TIFF over RAS, transcode RAS to TIFF in a controlled environment to avoid extra degradation
Ensure target printing pipelines accept the RAS bit depth and color space to avoid unexpected color shifts
Provide a sidecar JSON with key EXIF fields if the destination platform strips structured metadata from RAS

Verification, Privacy, and Performance

Keep originals: archive 3FR files before converting since RAS is intended for delivery not archival master copies
Process batches of 20-50 3FRs to balance RAM use and avoid browser timeouts during heavy demosaicing
Use local client-side conversion to prevent sensitive capture metadata from leaving your device
Validate a sample RAS on mobile and desktop to check accessibility and rendering consistency before bulk distribution
Remove sensitive GPS tags from 3FR sidecars if you will share RAS images publicly and metadata is retained

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.
