Hey Product Hunt! SubZero started as a free tool to remove captions from videos — no upload, no signup, everything processed locally in your browser. I just added a full PDF toolkit alongside it (merge, split, compress, watermark, and more), same privacy model: your files never leave your device. Also fully bilingual with Arabic/RTL support. Would love feedback — happy to answer anything about how it's built!
