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 Raw Data

Apply consistent camera white balance in CRW before batch export to minimize per-image color shifts
Avoid in-camera heavy JPEG rendering; keep CRW as native RAW to retain sensor detail until SFW render
Convert CRW from the same camera model together to reuse identical demosaic parameters
Check for clipped highlights in CRW histograms and recover shadows before finalizing SFW export
Use lossless CRW pre-processing for critical shoots to prevent additional compression artifacts

SFW Export Settings

Choose SFW lossless mode for archival to retain rendered pixel fidelity from CRW decodes
When reduced size is required, select SFW compression and accept minor chroma smoothing
If target supports ICC, embed profile to preserve color rendering from CRW decode
Select higher bit depth in SFW when target pipeline supports it to reduce posterization
Prefer resolution downscaling in one step to avoid repeated resampling artifacts

Software & Workflow

Use raw-capable editors that recognize Canon CRW tags to ensure accurate demosaic params
Validate SFW in your CMS and editor chain to confirm ICC and EXIF mapping correctness
Test a representative CRW file in your final editor before large batch exports to catch color shifts
For print workflows, convert CRW with the printer profile and embed that ICC into SFW if supported
Script batch export pipelines when consistent exposure and profile application are required

Verify Output Integrity

Inspect SFW pixel areas where CRW had high dynamic range for clipping introduced by quantization
Compare EXIF timestamps and focal metadata post-conversion to ensure mapping accuracy
Check for missing maker notes that may be crucial for provenance and camera serial validation
Confirm alpha presence in SFW only when explicit masking was applied prior to export
Re-open a sample SFW in target software to ensure rendering matches the expected CRW-derived look

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.
