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, photo-accurate CRW to HEIC conversion for photographers and designers preserving key image qualities where possible.

Fast Local Processing

Convert RAW CRW images to HEIC quickly in your browser without server uploads, minimizing transfer time.

Photographic Fidelity

Optimized HEIC encoding retains perceptual detail and reduces filesize while aiming to preserve tonal gradation.

Wide Device Support

HEIC outputs work on modern iOS, macOS and many image viewers while remaining efficient for mobile workflows.

Client-Side Privacy

Files are processed in browser memory buffers so source RAW CRW files are not uploaded to external servers.

Adjustable Encoding

Choose compression level and target resolution to balance image quality versus HEIC file size for various platforms.

Preserve Color Rendering

We attempt to map CRW camera color to HEIC output using embedded profile hints where available; verify in your workflow.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW Before Conversion

Apply camera corrections in your RAW editor so demosaic adjustments are baked into the raster output
Export color-locked previews from CRW if you need consistent white balance across a batch
Remove proprietary maker notes if they are not required to reduce metadata bloat in HEIC
Crop or straighten CRW images first to avoid recomputing transformations after HEIC encoding
Convert higher-exposure bracketed CRW sets into tuned masters before batch HEIC export

Control HEIC Encoding

Increase HEIC quality parameter to retain more midtone detail from CRW demosaic
Select 10-bit HEIC when available to better approximate CRW tonal range than 8-bit outputs
Use lossless HEIC options for archival copies if editor supports HEIF lossless profiles
Resize to intended delivery dimensions to reduce HEIC artifacts on sharp edges
Embed sRGB or the closest matching ICC profile when camera-specific profiles are unavailable

Validate Color and Metadata

Open a sample HEIC in target software to confirm white balance matches CRW-derived preview
Inspect EXIF fields after conversion to ensure orientation and GPS tags were transferred
Compare histograms between CRW processed preview and HEIC result for highlight clipping
Check embedded ICC profile in HEIC and reassign in your color-managed editor if needed
Verify that camera maker notes crucial to cataloging are present or exported separately

Batch Reliability & Privacy

Process CRW batches in groups of 20–50 to avoid browser memory pressure and ensure consistent encoding
Keep original CRW archives locally for future reprocessing rather than relying on HEIC as master
Use ZIP packaging for HEIC batches to maintain integrity during transfer to editors or clients
Disable background processes to reduce chance of browser timeouts during large CRW-to-HEIC jobs
Confirm that client-side processing settings meet your compliance or privacy requirements before converting

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.
