    Download the .xlsx output, export a batch ZIP, or choose "Convert & Swing" to transfer it to another device.

Frequently Asked Questions

What does this HEIF to XLSX route produce?

Export image metadata or a color summary in the target format. The output is a derived view; it does not preserve the complete source file.

Does the .heif file leave my device?

The conversion runs in your browser. Files are not uploaded to a conversion server.

Can I process large .heif files or batches?

There is no daily conversion quota. Large files and batch size depend on available browser memory and the format engine.
