What browsers are supported?

Chrome, Firefox, Safari and Edge (all recent versions). Any browser supporting WebAssembly will work.

Is there a watermark on converted SBV files?

No. Free conversions produce clean output with no watermarks. Your SBV file is identical to what a paid desktop tool would produce.

Yes! Chromebooks run Chrome browser, which fully supports Xonvert's WebAssembly-based conversion engine.

No — SBV preserves quality losslessly. Your output will be faithful to the original.

Absolutely. Drag files directly from your file manager onto the converter area. You can also click to browse, or paste from clipboard.

Yes. The settings panel lets you control output quality, resolution and format-specific parameters. Default settings are optimized for best results.

SBV is lossless, so quality settings primarily affect encoding speed rather than output fidelity. The default works perfectly.
