Istyle: Subtitle Style Editor

Make your subtitles fit the scene.

Open SRT, WebVTT or Advanced SubStation Alpha (ASS) subtitle files and see their lines in a live preview. Istyle detects styling already inside imported ASS files, so you can refine it instead of starting over.

Choose a typeface, text size, color, outline and shadow. Place captions at one of nine screen positions. Browse searchable fonts with live samples, including Roboto weights, serif styles and script-friendly fonts. Set bold, italic and underline independently. Choose colors with on-screen sliders and see each change in the preview.

Style one file or select a batch and apply one look across all of them. Save reusable presets on your device. Export styled ASS files to Jobs, where you can review, share or delete finished files.
