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?

Quickly convert JPG photos into Windows CUR icons optimized for cursors and small UI usage.

Fast JPG-to-CUR Conversion

Convert single images in seconds using in-browser processing, ideal for quick cursor creation and prototypes.

Smart Raster Sampling

Resampling preserves visible detail at small icon sizes while minimizing aliasing artifacts for cursor legibility.

Windows Cursor Compatibility

Output CUR files compatible with Windows cursor installers and many GUI toolchains for immediate use.

Alpha & Transparency Handling

Automatic alpha masking converts JPG's opaque pixels into transparency where you define transparency regions.

Precise Size & Hotspot Control

Select target icon sizes and hotspot coordinates so cursors align correctly in applications and OS settings.

Client-Side Processing

Files are processed in your browser memory; no external upload required, reducing exposure of private images.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare JPG Artwork for Icons

Crop the JPG to the intended cursor silhouette to avoid unwanted background pixels in the CUR
Increase contrast around the subject so resampling preserves recognizability at 16x16 or 24x24
Flatten any transparency substitutes in your JPG editor before masking to ensure consistent alpha conversion
Resize the JPG to a multiple of target icon dimensions before export to reduce interpolation artifacts
Remove heavy JPEG compression artifacts in the source to prevent blotchy pixels after downscaling

Encode for Target Cursor Needs

Choose 32-bit CUR when you require soft alpha edges from a masked JPG silhouette
Use indexed CUR variants for minimal palette cursors to reduce file size when photograph detail is unnecessary
Set the hotspot coordinate to align with interactive targets in your UI to avoid misclicks
Include multiple sizes in one CUR so Windows selects the best match for display scaling
Preview CURs on both standard and high-DPI monitors because color and scale differ across displays

Integrate with Editing & Deployment Tools

Open the produced CUR in icon editors like RealWorld to fine-tune pixel-level hotspots or alpha masks
Import CUR into installers or application resources to validate behavior before releasing builds
Convert CUR to ICO or PNG when targeting non-Windows platforms or web previews
Test CUR rendering in the exact target software (e.g., custom app or game engine) to confirm click alignment
Keep the original JPG in version control to regenerate variants with different sizes or masks

Verify Output for Privacy and Performance

Confirm that EXIF identifying data is not required post-conversion because CUR lacks standard metadata carriers
Process batches in groups of 20–50 to balance RAM usage and avoid browser slowdowns on large JPG sets
Close large image editors and unused tabs while converting to free memory for smoother resampling
Avoid uploading sensitive photographs; use local client-side conversion to maintain privacy
Download and inspect the CUR immediately to ensure hotspot, alpha, and scale match your requirements

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.
