Is this TTML to SSA converter free?

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

Why is my converted SSA file larger than the original TTML?

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 SSA 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 SSA files?

No. Free conversions produce clean output with no watermarks. Your SSA 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 TTML to SSA?

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

Does this tool support drag and drop?

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