UMARIX Compress, Convert, Trim and Edit Video for Free
17 professional video tools for students, creators, teachers, sellers, marketers and small businesses. Every tool runs entirely in your browser with FFmpeg.wasm â your videos are never uploaded, stored, or sent to any server. No account, no registration, and no watermark added by this site.
No artificial usage limit: real speed and maximum size depend on your device and browser. Large or long videos are slower and may run out of browser memory. The video engine (about 32 MB) downloads only after you choose a file and press Process â never automatically on page load.

- Privacy by design: browser-only processing means there is no server copy of your videos to leak, retain, or delete.
- Honest subtitles and watermarks: subtitles are added as a selectable track (not burned in), and text watermarks are rendered to an image and overlaid â both limits are stated on the tool pages, never hidden.
- Real results, not estimates: the compressor shows the actual output file size, and every tool downloads a real file produced from your video.
- Fast and mobile-friendly: tools work on phones and desktops, with clear warnings for large files instead of silent failures.
Who is this for?
Content creators preparing YouTube, TikTok, Instagram and Reels videos; teachers and students trimming lectures and assignments; online sellers preparing product videos; marketers making short clips and GIFs; and anyone who needs a quick, private video edit without installing software or creating an account.
Frequently asked questions
Are these tools really free?
Yes. There is no payment, no account and no watermark added by this site. The only cost is your own device time and data for the one-time engine download (about 32 MB).
Do you upload or keep my videos?
No. Processing happens in your browser. The site has no server upload path for videos, so there is nothing to store, share or delete server-side.
Why do large videos fail sometimes?
Browsers limit memory per page. A long or high-resolution video can exceed that limit, especially on a phone. Trim or compress a shorter clip first, or use a desktop browser for large files.
Will this site guarantee search rankings or earnings?
No. No page on this site guarantees rankings, traffic or earnings. The tools are provided as-is for genuine, everyday video tasks.
