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, browser-based CRW to AVIF conversion optimized for device sharing and reduced bandwidth use

Fast Local Processing

Convert high-resolution CRW files quickly in-browser using multi-core decoding to avoid uploads.

Retain Camera Detail

AVIF output preserves photographic detail and chroma when encoded with appropriate quality settings.

Wide Playback Support

Produce AVIF images that modern browsers and recent mobile OS versions can display natively.

Client-Side Privacy

CRW files are parsed in memory; original raws are not transmitted to external servers by default.

Bulk Conversion Ready

Efficient batch pipeline handles dozens of CRW files, grouping to reduce peak memory use.

Adjustable Encoding

Choose AVIF quality and chroma subsampling to balance file size and fidelity for sharing.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare RAW Rendering

Perform exposure and white-balance corrections in a RAW editor before conversion to lock rendered RGB values
Apply lens corrections and remove chromatic aberration to reduce encoder artifacts in AVIF
Export a high-bit-depth raster if you need smoother gradients before AVIF compression
Flatten any HDR merges into a single 32-bit or 16-bit raster to avoid tone-mapping surprises
Embed or export an sRGB or desired ICC profile from your RAW processor to guide AVIF color handling

AVIF Encoding Choices

Choose lossless AVIF when archival fidelity from CRW is required to avoid quantization
Use higher AVIF quality and reduced chroma subsampling to preserve fine detail in high-ISO CRW captures
Prefer 10–12 bit AVIF output when available to maintain smooth gradients from 12–14 bit CRW sources
Test different quantization settings on representative CRW files to find the best size/quality balance
Enable profile embedding in the encoder to retain CRW color intent when the workflow supports it

Workflow Compatibility

Confirm target device or CMS supports AVIF before choosing it as the primary delivery format
Provide fallback JPEG or PNG for recipients using older editors or browsers without AVIF support
Store original CRW files separately as the editable master for future re-exports or edits
When sending to clients, include a proof PNG or JPEG for quick visual checks alongside AVIF
Validate color and sharpness in both web and native image viewers to catch rendering differences

Verification & Performance

Inspect resulting AVIF metadata to confirm critical EXIF fields were retained from the CRW
Compare histograms pre- and post-conversion to detect unwanted clipping or quantization
Process batches in groups of 20–50 CRW files to avoid browser memory pressure and slowdowns
Use higher-quality settings for print-intended AVIF; lower quality is acceptable for device sharing
Keep locally archived CRW originals until AVIF outputs are reviewed and approved

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.
