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 AVIF images into Windows cursor (CUR) files quickly and reliably for app icons and accessibility tooling.

Fast AVIF to CUR

Client-side conversion minimizes upload time and delivers CUR files within seconds for single images.

Preserve Visual Fidelity

We rasterize AVIF frames at source resolution and aim to retain sharpness suitable for cursor sizes.

Windows Cursor Ready

Outputs a .cur container compatible with Windows cursors and many desktop environments.

Local Processing

Files are processed in-browser memory buffers so your AVIF images do not leave the device.

Size & Hotspot Options

Choose export resolution and define cursor hotspot coordinates for correct pointer behavior.

Alpha Handling

Alpha transparency is flattened or preserved depending on source AVIF and CUR format limitations explained below.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare AVIF Source Layers

Flatten AVIF layered edits in an editor to control final raster appearance when converting to CUR
Apply orientation and rotate AVIF before conversion so CUR hotspot mapping matches visual cursor direction
Convert AVIF with premultiplied alpha resolved to avoid semi-transparent fringing in the CUR result
Resize AVIF to target cursor dimensions to preserve edge sharpness instead of relying on automated downscaling
Export a clean background or matte in AVIF if you intend to composite the cursor over non-solid backgrounds

Target CUR Encoding

Choose 32-bit RGBA export to retain transparency pixels when CUR supports alpha on the target system
Avoid embedding ICC in CUR; instead convert AVIF to sRGB beforehand to reduce color mismatches
For small cursor sizes, prefer sharpening AVIF slightly before rasterization to keep icon legibility
Use exact hotspot coordinates tied to cursor content to ensure correct click-target behavior in apps
When creating multiple sizes, generate each size from the same high-resolution AVIF to ensure consistency

Workflow & Platform Interop

Test the produced CUR on the final Windows version or desktop environment to confirm mask and hotspot behavior
If an AVIF uses animation, export the intended static frame explicitly because animated semantics are not preserved
Verify that the CUR file is recognized by target software; some design tools prefer ICO wrappers for icon management
When sharing across platforms, include PNG fallbacks created from the same AVIF to support non-CUR consumers
Document color differences caused by downsampling high-bit AVIFs and provide a reference PNG for designers

Verification, Privacy & Performance

Confirm transparency by testing cursors against typical UI themes, dark and light, before distribution
Keep originals: archive AVIF sources so you can re-export different cursor sizes or reapply color profiles
Batch-convert groups of 20–50 AVIFs to balance throughput and browser memory usage
Process conversions locally in the browser to keep private artwork from leaving the device
Download finished CUR packages promptly and remove temporary data from the browser if working on shared machines

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.
