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-ready conversion from Canon CRW raw captures to CUR cursor bitmaps for localized UI and prototyping.

Optimized Batch Throughput

Process large CRW libraries in queued batches to generate many CUR cursors without manual export steps.

Controlled Raster Rendering

Reliable rasterization from CRW raw pixels to CUR bitmap with adjustable scaling and sharpening prior to export.

Batch Profile Presets

Save and apply conversion profiles for consistent CUR sizes, hotspots, and DPI across hundreds of images.

Windows Cursor Compatibility

Output CUR files compliant with Windows cursor containers for .cur usage and resource embedding.

Resolution & Hotspot Controls

Define output pixel dimensions and cursor hotspot coordinates for precise pointer behavior in target apps.

Local Client-Side Processing

Conversion happens in the browser; source CRW files do not upload to external servers unless you choose otherwise.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW Before Export

Demosaic CRW with consistent white balance to avoid hue shifts in small CUR bitmaps
Apply lens corrections in RAW editor to prevent edge artifacts after downscaling
Export a flattened sRGB bitmap if you rely on a specific tonal rendering for CUR
Crop CRW to the intended hotspot framing to minimize post-export pixel loss
Remove unnecessary shadow/highlight extremes in CRW to maintain clarity at cursor sizes

Configure CUR Encoding

Choose proper target dimensions (16/32/48 px) to avoid bilateral scaling artifacts
Generate alpha masks from CRW transparency intent using feathered edges for smooth cursors
Use 32-bit BGRA output when creating CUR to ensure modern alpha support in Windows
Set hotspot coordinates relative to cropped CRW output to guarantee pointer alignment
When batch exporting, standardize DPI and scaling to keep multiple CURs visually consistent

Validate on Target Platforms

Open CUR in a Windows cursor editor to verify hotspot behavior before deployment
Test CURs in the actual application or OS to confirm perceived sharpness and alignment
Compare rendered CUR pixels against a 100% zoom of CRW-derived bitmap to spot artifacts
Check cursor visibility on intended background colors and multiple display gammas
Confirm that CUR multi-frame assemblies behave as expected in your target environment

Batch Reliability & Privacy

Process CRW files in groups of 20-50 to balance memory use and throughput in-browser
Keep original CRW archives locally to allow re-renders if CUR artifacts appear
Use ZIP packaging after conversion to ease distribution while keeping CUR integrity
Disable background apps to free CPU threads for consistent batch conversion times
Ensure you export sidecar metadata if camera EXIF must be referenced outside CUR

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.
