Video & PDF tools that run in your browser — not on someone's server
Compress, convert, trim, transcribe, merge. The work happens on your device with standard browser tech, so your file never uploads. No account, no watermark, no size cap from us.
No tools match that. Try “video”, “image”, “audio”, or “pdf”.

Frequently asked questions
Is Vootkit really free?
Yes. Every tool is free with no watermarks and no sign-up. The site is supported by ads.
Are my files uploaded anywhere?
No. The compressor, GIF maker, and thumbnail maker process your files locally in your browser, so they never leave your device.
Can I use the thumbnails and GIFs commercially?
You can use anything you create from files you own or have the rights to. Vootkit doesn't add any watermark or claim over your output.
Does Vootkit download videos from YouTube or TikTok?
No. Vootkit only works on files you provide. It is not a downloader and isn't affiliated with any video platform.
What video formats are supported?
Common formats like MP4, MOV, and WebM work in modern browsers. The compressor exports WebM; the thumbnail maker exports PNG; subtitles export as .SRT or .VTT.

On a phone? Phones have limited memory, so keep clips short (under ~2–3 minutes) for best results. If a video's audio won't load, run it through the Audio Extractor first (export MP3), then drop that here — it's the most reliable path on mobile.
