Is batch conversion available?

Yes. Drag or select multiple SRT files and they'll all convert to SMI simultaneously. Download results individually or as a ZIP.

Is this SRT to SMI converter free?

Yes, completely free. No registration, no hidden fees. Free users can convert files with Xonvert's full engine.

Why is my converted SMI file larger than the original SRT?

File size depends on compression settings and content complexity. Try the Medium quality preset for smaller output, or the file may simply contain data that resists SMI compression.

What browsers are supported?

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

Is there a watermark on converted SMI files?

No. Free conversions produce clean output with no watermarks. Your SMI 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.

Will I lose quality converting SRT to SMI?

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