Is there a watermark on converted CRT files?

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

Will this converter work on Chromebook?

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

No — CRT 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.

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

Yes. Xonvert works in any modern browser on any operating system — Linux, Windows, macOS, ChromeOS, and mobile platforms all supported.
