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, technical ARW to SUN conversions optimized for photographers who need reliable raster results and clear tradeoffs between quality and size.

Raw to Ready Fast

Convert large Sony ARW raw files to SUN quickly with multi-threaded browser processing for immediate preview and export.

High-Fidelity Rasterization

Careful demosaic and color rendering produce accurate SUN raster images while exposing tradeoffs for bit depth and compression.

Batch Workflow

Process dozens of ARW files in a single session and output SUN files or a ZIP archive to speed catalog exports.

Editing-Compatible Output

SUN results are suitable for target editors that accept SUN; expect pixel-based files ready for print or downstream retouching.

Local Client Processing

Conversion runs in the browser memory buffers to reduce remote exposure of camera RAW data and metadata risk.

Control Over Output

Adjust resolution and basic color options to balance SUN file size versus retained tonal and chroma detail.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare ARW for Rasterization

Inspect ARW white balance and apply a global correction before export to ensure SUN pixels reflect intended color
Convert RAW exposure adjustments in an editor rather than relying on SUN compression to recover blown highlights
Export ARW to a linear or camera RGB preview when you need accurate demosaic interpolation for professional retouching
Generate sidecar XMP from ARW to preserve edit settings since SUN conversion may not carry complex edit instructions
Strip unnecessary proprietary maker notes only after confirming that your cataloging workflow no longer requires them

Choose SUN Encoding Wisely

Select lossless SUN to preserve demosaiced detail from ARW when subsequent editing is expected
Use 16-bit SUN output when converting high dynamic range ARW captures to retain tone-mapping headroom
If storage is constrained, test lossy SUN compression on representative ARW images and inspect fine detail loss
Embed ICC profiles into SUN when your printing pipeline requires color-managed files for consistent proofs
Avoid aggressive SUN resizing during conversion if you plan precise pixel-level retouching later

Verify in Your Target Workflow

Open converted SUN in the exact editor or viewer used for final output to check color rendering differences
Compare histograms of ARW and SUN exports to confirm that shadow clipping or highlight rolloff is acceptable
Confirm that lens correction metadata from ARW is applied prior to SUN export, since SUN cannot apply geometric fixes
Check that EXIF timestamp and focal length fields carried into SUN match your cataloging requirements
Validate print proof patches after conversion to ensure perceived contrast matches the ARW-based soft-proof

Optimize Privacy and Throughput

Process batches of 20–50 ARW files to keep browser memory steady and reduce the chance of tab crashes
Close background applications that consume CPU when converting large ARW files to SUN for faster demosaic
Keep original ARW files archived until you confirm SUN outputs meet both pixel and metadata needs
Use local processing to minimize network transfer of sensitive ARW capture data when converting to SUN
Download converted SUN packages promptly and clear temporary in-memory caches to maintain device performance

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.
