Can I convert password-protected CUR files?

Encrypted or DRM-protected files cannot be converted. You'll need to remove protection first using the original software.

Can I convert multiple CUR files at once?

Yes! Drag multiple files into the converter for batch processing. All files convert simultaneously and can be downloaded as a ZIP archive.

What's the maximum number of files I can convert at once?

Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.

Why choose J2K over other formats?

JPEG 2000 Codestream offers wavelet compression with superior quality at low bitrates. It's widely used for medical imaging (DICOM), digital cinema (DCI) and satellite imagery, making it an excellent choice for most image needs.

Will my CUR file be deleted after conversion?

No. Your original CUR file is never modified or deleted. Xonvert creates a separate J2K copy — your source file remains untouched.

What image quality settings should I use?

For photos, use the High quality preset. For web graphics, Medium offers a good size-quality balance. The default preset works well for most use cases.
