SubZero is two free browser tools in one: remove captions/subtitles from videos, and a full PDF toolkit — merge, split, rotate, compress, watermark, extract pages, images→PDF, PDF→JPG, and more. Everything runs 100% locally in your browser (video via ffmpeg.wasm, PDFs via pdf-lib/pdf.js) — your files never get uploaded, no signup, no watermark on output. Also bilingual (English/Arabic, full RTL support




The local processing angle is genuinely useful for anyone dealing with sensitive docs, and the bilingual RTL support is a thoughtful touch. One thing I'd love to see is batch processing for the PDF toolkit - dropping in 20 files and merging or compressing them all at once would save a lot of time compared to handling them one by one.
Tried the subtitle remover on a short clip and it actually worked without me uploading anything, which was kind of the whole point. The PDF merge was also smooth, no fuss at all.
the fact that all processing runs locally in the browser with ffmpeg.wasm feels genuinely well-thought-out, especially for privacy. love seeing full RTL support alongside English too.
