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?

Convert Windows cursor files (CUR) to editable BMP bitmaps quickly and reliably for batch workflows and tooling.

Fast Batch Processing

Process hundreds of CUR files into BMP in streamlined batches with predictable throughput.

Pixel-Accurate Rasterization

Rasterizes CUR cursor bitmaps to full-resolution BMP pixels without lossy color subsampling.

Broad Editor Support

Output BMP files open in Photoshop, GIMP, Paint.NET and native Windows tools for editing.

Batch-Friendly Controls

Queue multiple CUR files and download a single ZIP of BMP outputs for pipeline integration.

Preserves Cursor Frames

Extracts the static image frame from single-image CUR entries; multi-frame CURs handled per file.

No Server Upload Required

Conversions run client-side in the browser to reduce transfer time and keep files local.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CUR Sources

Inspect CUR entries for multiple size variants and choose the intended frame prior to batch conversion
Note hotspot coordinates and save them in filenames or a sidecar manifest when cursor positioning matters
Identify indexed palette CURs and expect them to be expanded to full RGB in BMP outputs
Validate that any 32-bit ARGB cursor uses straight or premultiplied alpha so you can handle flattening rules
Reject corrupted CUR headers to avoid producing malformed BMP files in batches

Target BMP Handling

Select 32-bit BMP when source CUR contains alpha and your editor supports BMP alpha channels
If your workflow requires transparent backgrounds, convert BMP to PNG after export for consistent alpha across tools
Anticipate increased file size when expanding indexed CUR palettes into uncompressed BMP pixels
Use ZIP packaging for batch BMP outputs to reduce transfer overhead and preserve original filenames
Set naming patterns to include original CUR dimensions to simplify downstream editing and sorting

Verify Outputs

Open a sample BMP in your target editor to confirm alpha channel interpretation before processing full batches
Check color fidelity against original CUR visuals when ICC/EXIF is absent and adjust color space in editor
Compare pixel-level edges at 100% zoom to detect palette-to-RGB conversion artifacts
Confirm that hotspot behavior is recreated in your application if required, or keep hotspot metadata external
Validate multiple size variants from a CUR to ensure correct frame selection for each BMP export

Batch Reliability & Privacy

Process batches in groups of 20–50 CUR files to limit browser memory pressure and minimize failures
Keep conversion client-side to avoid sending cursor images over the network and maintain privacy
Close other CPU- and memory-intensive tabs to maximize conversion throughput during large batches
Retry failed items individually and log source CUR offsets to aid reproducible reprocessing
Download ZIP archives promptly and clear browser memory to prevent retention of sensitive cursor assets

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.
