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, camera-accurate ARW to OTB conversion tuned for web publishing workflows and efficient offline editing pipelines.

Fast, Camera-Native Decode

Direct demosaicing of ARW sensor data with efficient pipeline to minimize processing time for batches.

Preserve Raw Detail

Retains native linear sensor dynamic range in intermediate steps so OTB output keeps tonal headroom for edit-first workflows.

OTB Ready for Editors

Produces OTB files structured for offline editors that expect tiled, editable bitmaps rather than proprietary RAW containers.

Client-Side Processing

Conversion runs locally in browser memory to keep camera originals on-device and reduce upload exposure.

Batch-Friendly

Optimized queueing and progressive conversion for dozens to hundreds of ARW files without manual per-file reconfiguration.

Adjustable Output Parameters

Control target bit depth and tiling options so OTB artifacts and size meet web or editorial needs.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare ARW Inputs

Inspect ARW exposure and shadow clipping before decode to avoid irreversible highlight flattening
Export sidecar XMP from your raw editor to retain param edits that OTB cannot natively express
Apply lens corrections to ARW when required; converting uncorrected raws embeds distortion into OTB pixels
Convert from camera linear space to a working color space during decode to maintain color predictability in OTB
For multi-exposure shoots, merge or bracket in RAW before OTB export to preserve dynamic range in a single raster

Configure OTB Output

Choose 16-bit OTB when you plan heavy retouching to retain ARW tonal information
Enable lossless tile compression only if your editorial tools support OTB compression transparency
Set tile size to match your editor recommendations to optimize read performance and memory use
Embed ICC profile into OTB if downstream tools need consistent color mapping; verify reader compatibility
Export a compressed web derivative (JPEG/WebP) from OTB for publishing to reduce bandwidth

Workflow Integration

Use OTB as an intermediate for editors that lack native ARW support to preserve editability
Automate batch ARW-to-OTB flows in your DAM to keep originals untouched and store OTB for editing
Validate OTB files in your target CMS or editor because different OTB readers handle tags differently
Keep original ARW alongside OTB to allow reprocessing with improved demosaic settings later
Document conversion settings per shoot (white balance, demosaic, bit depth) to reproduce results

Verify Quality and Privacy

Check OTB pixels for demosaic artifacts at 200% when converting high-ISO ARW files
Export EXIF/XMP sidecars during conversion to guarantee metadata continuity across systems
Process batches locally to keep camera serials and GPS data on-device unless sidecar export is used
Monitor memory use when converting many 42–60MP ARW files to avoid browser crashes
Download converted packages promptly and remove temporary files to reduce local exposure

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.
