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 BMP conversion optimized for batch workflows and pixel-accurate raster outputs

Batch-Oriented Throughput

Process large CRW shoots quickly with parallel browser-side conversion to BMP for downstream editing.

Pixel-Accurate Raster Output

Produces uncompressed BMP bitmaps that preserve pixel data fidelity from decoded CRW sources.

Wide Editor Support

BMP results open in Photoshop, GIMP, Paint.NET and legacy image pipelines without container decoding.

Consistent Batch Results

Deterministic processing ensures each CRW in a batch produces comparable BMP files for cataloging.

Client-Side Memory Processing

Conversions are performed in browser memory buffers to minimize network transfer and protect originals.

Customizable Output Options

Choose bit-depth and dimensions before converting CRW files to BMP to match print or archival needs.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare RAW for Decode

Verify CRW exposure and white balance settings before batch decode to avoid per-image manual corrections
Keep original CRW files until BMP outputs are validated to preserve RAW-level edits and metadata
Convert CRW with consistent demosaic settings across a shoot to maintain tonal uniformity in BMP outputs
If CRW includes multiple embedded previews, explicitly choose RAW decode to avoid accidental preview-based BMPs
Document camera model and lens metadata from CRW so downstream editors can apply matching lens profiles

Optimize BMP Storage

Expect BMP output to expand relative to CRW; allocate disk space before large batch exports
When archival size matters, compress BMP outputs into ZIP containers post-conversion for storage
If a lower footprint is acceptable, choose 8-bit BMP instead of 24/32-bit to reduce file-size per image
Split large shoots into sub-batches to stage writes and prevent temporary storage spikes during conversion
Keep a manifest linking each BMP to its original CRW filename and metadata for catalog integrity

Validate Color and Detail

Compare BMP pixel detail at 100% against CRW RAW previews to confirm demosaic and sharpening choices
Check color shifts by loading BMP in the target editor using the same working color space you used for decode
Inspect shadow and highlight roll-off in BMP to ensure important dynamic range from CRW is preserved
If CRW contained an ICC profile, verify the BMP render in viewers that honor embedded profiles or apply profiles manually
Spot-check a subset of converted BMPs from each batch to detect systemic decode or scaling issues early

Batch Stability & Privacy

Process batches of 20–50 CRW files to balance throughput and browser memory constraints for stable BMP exports
Run conversions locally to keep CRW sensor data on device; do not upload raw originals if privacy is required
Close resource-heavy apps during large batches to prevent memory swapping that can corrupt writes
Verify each ZIP archive after batch completion to ensure every BMP file was written successfully
Remove temporary buffers and caches after conversion to free memory and reduce risk of stale data exposure

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.
