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, batch-oriented CRW to RGBA conversion with predictable raster output for editing and web workflows.

Optimized Batch Throughput

Process hundreds of CRW files in grouped batches to minimize memory overhead and complete large jobs faster.

High-Fidelity Rasterization

Convert CRW raw sensor data to full RGBA raster with preserved per-pixel color fidelity within software decoding limits.

Robust Batch Controls

Queue, limit and parallelize conversions so desktop browsers handle many CRW images without frequent crashes.

Editor-Friendly Outputs

RGBA PNG/TIFF-ready images compatible with Photoshop, GIMP, and browser canvases for immediate editing.

Client-Side Processing

Files are decoded in-browser memory buffers; no CRW files are uploaded by default, improving privacy and speed.

Archive-Ready Results

Download converted RGBA files individually or as a ZIP, simplifying archival and distribution workflows.

Source vs Target Format

Key technical differences between formats

Feature	Source Format	Target Format
Compression	Canon raw compressed or lossless packaging	Uncompressed or lossless RGBA bitmap
File Size	Compact raw, sensor-encoded	Larger RGBA bitmaps, up to 4x raw size
Quality	Raw sensor with demosaic potential	Lossless per-pixel RGBA after decode
Transparency	Not applicable	Supported (alpha channel present but opaque)
Metadata	EXIF, maker notes, thumbnails	Possible EXIF/ICC depending on wrapper
Primary Use	Capture and archival of sensor data	Editing, compositing and web-ready assets

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW Source Properly

Inspect CRW EXIF for orientation and mirror tags before bulk decode to avoid re-rotating outputs
Apply any white balance or exposure presets in your raw chain prior to conversion to reduce per-file corrections
Confirm whether CRW contains Canon maker notes that affect demosaic choices; adjust test parameters accordingly
Trim corrupted CRW files out of the batch to prevent decode failures stopping the entire queue
If you need embedded thumbnails, extract them separately—CRW-to-RGBA focuses on full raster output not thumbnails

Select RGBA Export Strategy

Choose PNG for lossless alpha-capable RGBA and TIFF if you require higher bit-depth support where available
Expect RGBA outputs to be larger; plan storage and ZIP grouping for archival transfers
When exporting 16-bit RGBA, confirm the target editor accepts 16-bit PNG/TIFF to avoid silent downsampling
Use checked export wrappers that preserve orientation to avoid manual reorientation in editors
If preserving camera color rendering matters, export a test pair and compare histograms before batch processing

Verify Outputs for Editing

Open a sample RGBA file in your intended editor to confirm expected color and alpha behavior before full batch
Compare shadow and highlight detail at 100% to detect any demosaic-induced artifacts early
Check for banding by inspecting gradients in converted RGBA at native bit depth
Validate that embedded ICC (if present) renders correctly in target software; reassign if necessary
Confirm that orientation, crop and pixel dimensions match project requirements to avoid re-export cycles

Batch Reliability & Privacy

Process CRW in groups of 20–50 to balance memory usage and throughput and reduce browser OOM incidents
Run conversions locally in the browser to keep CRW files off servers when privacy is required
Close heavy background apps and browser tabs to free memory and avoid CPU throttling during mass decodes
If network upload is used for ZIP retrieval, ensure stable bandwidth to avoid corrupted downloads
Download and verify each ZIP package integrity promptly; re-run small batches for any failed items

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.
