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, reliable CRW to MNG conversion optimized for batch workflows and animation-aware outputs

Fast Batch Processing

Convert large CRW collections using multi-file pipelines to accelerate production throughput.

Preserve Raw Detail

Extract CRW raw sensor data into high-fidelity raster frames to retain tonal range for MNG sequences.

Optimized for Batches

Queue and process hundreds of CRW files in groups to balance memory and throughput.

Broad Playback Targets

Exported MNG sequences are suitable for editors and viewers that accept animated PNG containers.

Adjustable Export Parameters

Configure frame rate, color depth conversion, and compression level for each batch.

Local, Memory-Only Processing

Files convert in browser memory without mandatory uploads, reducing external exposure.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare Raw CRW Inputs

Sort CRW files by capture timestamp to ensure intended animation frame order
Apply a consistent white balance to CRW files before batch conversion to avoid color drift
Convert CRW using the same demosaic algorithm across a batch to keep grain and detail consistent
Reject or flag CRW previews; converter selects the primary raw frame rather than embedded JPEGs
Normalize exposure or apply identical highlight recovery presets to avoid flicker between frames

Configure MNG Encoding

Choose 16-bit output only when target playback supports it; otherwise use 8-bit to save size
Select PNG-style lossless compression to retain decoded CRW detail for editing workflows
Enable frame timing controls to set milliseconds per frame for intended playback speed
Embed ICC profiles when available but reproof in a color-managed application after export
Use per-frame delta compression sparingly; it reduces size but can amplify noise between CRW frames

Validate Output Across Tools

Open MNG in target viewer (GIMP or sequence-capable players) to verify frame ordering and timing
Inspect a subset of exported frames at 100% to confirm demosaic artifact absence
Check embedded metadata fields such as DateTime and CameraMake for fidelity after export
Compare histogram peaks between a CRW source and corresponding MNG frame to detect clipping
Test alpha presence only when supplying external masks; CRW alone will produce opaque frames

Batch Reliability & Privacy

Process large CRW batches in groups of 20–50 to limit peak RAM usage in the browser
Keep source CRW archives locally until you verify critical metadata post-convert
Close memory-heavy tabs and apps to reduce demosaic time variance across the batch
When automating, validate a small representative batch before committing entire shooting sets
Download converted ZIP packages promptly and purge temporary memory buffers when done

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.
