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.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW for Decode

Apply camera white balance in RAW editor before export to ensure JP2 color matches photographer intent
Convert CRW sensor linear data to a working color space; avoid baking incorrect camera matrices into JP2
Demosaic CRW in a trusted RAW processor to control noise reduction prior to JP2 encoding
Embed a standard ICC profile when exporting processed raster from CRW to provide consistent JP2 color metadata
Flatten any edits that rely on RAW-side parametric controls because JP2 will store only the rendered raster

Choose JP2 Encoding

Select lossless JP2 if you need archival fidelity and to retain as much decoded CRW detail as possible
Use visually lossless wavelet settings to reduce file size while preserving highlight and shadow gradation
Prefer 16-bit JP2 for critical prints when the downstream app supports 16-bit decoding
Disable chroma subsampling for images with fine color transitions to avoid color banding in JP2
Test different compression ratios on representative CRW frames to find the best quality-size trade-off

Verify Output in Workflow

Open JP2 in your target editor to confirm ICC profile presence and correct rendering after CRW decode
Compare histograms between CRW-derived render and JP2 to detect clipping introduced during encoding
Inspect crops and fine detail at 100% to ensure JP2 wavelet artifacts are acceptable
Check timestamps and EXIF fields in the JP2 metadata to confirm necessary provenance was transferred
Validate JP2 compatibility in your DAM or print pipeline before committing large archival batches

Manage Privacy and Performance

Process CRW files client-side to keep raw camera files on-device and reduce exposure of maker data
Convert batches of 20–50 CRW images to balance memory use and throughput when generating JP2 archives
Close background applications that compete for RAM to maintain stable performance during large CRW jobs
Download JP2 outputs promptly and verify checksums if you rely on accurate archival copies
Avoid network-dependent processing steps for sensitive CRW files; prefer local decoding and JP2 encoding

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.
