คำถามที่พบบ่อย — Subtitle Editor & Timing Shifter

Nowhere. The Subtitle Editor & Timing Shifter operates entirely client-side. Your files are processed inside your browser and are never uploaded to any remote servers, ensuring maximum privacy.
Since processing runs locally, the maximum limit depends on your device's memory (RAM) and browser limits. We suggest uploading moderately sized files for optimal speed.
The tool exports your files in high-quality, standard formats (like PNG, JPG, or PDF) that are fully compatible with external editors and viewers.
