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

Confirm camera white balance in the CRW before decoding to avoid baked-in shifts in the TIFF
Apply or note any custom lens calibration stored in maker notes; converter may not map it automatically
Convert from the highest native CRW resolution to retain sensor detail when writing 16-bit TIFF
Avoid in-camera JPEG previews as primary source; use the raw pixel data for TIFF decoding
Verify that CRW isn’t corrupted by opening in a raw viewer before batch export

Configure TIFF Encoding

Choose 16-bit TIFF when preserving highlight-to-shadow transitions from CRW demosaicing
Select LZW or ZIP compression to reduce TIFF size while keeping editability intact
Embed an ICC profile at export to maintain color intent into desktop editors
Disable chroma subsampling; TIFF stores full per-channel samples for accurate color
Set output dimensions to match print target to avoid unnecessary resampling

Verify Post-Export Integrity

Open the TIFF in Photoshop or a raw-capable viewer to compare shadow detail versus CRW rendering
Check embedded EXIF and XMP fields in the TIFF to ensure essential tags were mapped
Inspect color profile assignment and convert workspace only when needed to avoid double transforms
Zoom to 100% to inspect demosaicing artifacts or moiré introduced during decode
Validate file checksum or sidecar record when archiving TIFFs created from important CRW batches

Workflow Resilience & Privacy

Keep original CRW files until TIFFs pass visual and metadata verification to ensure reversibility
Process batches in groups of 20–50 to reduce browser memory pressure and avoid timeouts
Run conversions client-side to minimize exposure of original CRW files to external servers
If maker notes are critical, export CRW backups using vendor utilities that guarantee proprietary tag retention
Download TIFF archives promptly and store on redundant media for archival safety

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.
