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
Have been burned before by tools claiming "all local" so I really appreciate seeing the ffmpeg.wasm setup openly explained, that builds trust. One thing I'd love as an addition is a batch queue for the video side, so you could drop in ten clips with subtitles and remove them all at once instead of running them one at a time. Would make it way more useful for anyone working through a backlog of downloads.
@nehirnpjk thx for your review
And i will truly work on the multiple vids uploading,
Really glad this is all local, the privacy angle is huge. One thing I'd love to see is batch video subtitle removal - dropping in a folder of clips and letting them process in one go would save a ton of time when cleaning up series content.
@mesut378567 that’s actually a great suggestion, thank you!
A batch queue would be super useful — being able to drop in multiple videos at once and let it process them in the background while I do something else. Right now it feels like one file at a time keeps you tethered to the tab.
honestly the privacy angle is what got me, doing everything locally is such a nice touch. one thing that would be super useful though is batch processing for the PDF tools, like being able to merge or compress a whole folder of files at once instead of doing them one by one.
Love that everything stays local, makes it feel safe to throw sensitive PDFs at it. One thing I'd love is a batch queue for the video tool so I can drop in a folder of clips and have the captions stripped from all of them while I walk away.
Stripped the hardcoded subs off a downloaded lecture video in seconds without re-uploading anything, huge plus. Also merged and rotated a stack of scanned PDFs in one go, super smooth for a free tool.
