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, high-fidelity ARW to HEIF conversion tailored for photographers balancing quality and file size.

Optimized Speed

Browser-based conversion that minimizes wait with progressive decoding tuned for common ARW sizes.

High Visual Fidelity

Preserves full raster image from ARW raw decode into HEIF with minimal perceptual quality loss at high settings.

Reduced File Sizes

HEIF’s modern compression yields substantially smaller files than TIFF while keeping comparable visual detail.

Wide Playback Support

Produces HEIF files broadly supported by modern macOS, iOS, and recent photo apps for efficient workflows.

Client-side Processing

Conversions run in the browser memory; files are not uploaded to external servers, reducing exposure risk.

Adjustable Encoding

Choose HEIF quality and chroma options to trade off between artifacting and compression ratio.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare Raw Decode

Set desired white balance in raw workflow before conversion because ARW demosaicing bakes WB into the raster
Demosaic ARW at target resolution to avoid later resampling artifacts in HEIF encoding
Apply lens corrections prior to export since HEIF output will be a flattened image without editable correction stacks
Export ARW exposures you want preserved as separate files rather than relying on single-shot tone adjustments
Use a calibrated monitor and source ICC when preparing ARW to reduce color shifts during HEIF encoding

Choose HEIF Encoding

Select 10–12 bit HEIF output for smoother shadow gradients extracted from ARW raw data
Prefer lower chroma subsampling (4:4:4 or 4:2:0 depending on profile) when fine color detail matters from ARW sensors
Increase HEVC quality factor to minimize block or banding artifacts visible in flat-tone regions
When file-size matters, test medium quality with visual inspection at 100% to balance artifacts versus savings
If your target software lacks HEIF bit-depth support, export a high-quality JPEG copy alongside HEIF

Workflow Compatibility

Confirm target editor supports HEIF’s HEVC flavor before replacing ARW archives in production pipelines
For cross-platform delivery, provide a JPEG fallback since some CMS and web services lack HEIF ingestion
Import HEIF back into editors that support embedded ICC profiles to retain chosen color management from ARW
Maintain original ARW files as masters because HEIF is a compressed derivative unsuitable for raw rework
When collaborating, include a text sidecar listing critical EXIF fields that may have been reformat-mapped

Verify and Secure Outputs

Check GPS and timestamp EXIF fields in HEIF after conversion since some ARW proprietary tags might not map
Use a metadata viewer to confirm ICC profile presence if color fidelity is mission-critical
Validate output images on the same display family used by stakeholders to detect perceptual differences
Encrypt or password-protect ZIP batches when transferring many HEIF files containing sensitive EXIF data
Retain original ARW files in secure storage until post-production and client approval are complete

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.
