Free Online Video Tools
These tools run FFmpeg compiled to WebAssembly, so the encoding happens on your own CPU instead of on someone else’s server. The trade-off is honest: the first load pulls down the FFmpeg core, and a long clip takes real time to process because your laptop is doing the work. In return, a 500 MB file never gets uploaded, there is no queue behind other people’s jobs, no watermark burned into the output, and no daily cap. Compress a screen recording that is too large to email, trim the first two minutes of dead air off a demo, pull a GIF out of a product clip, or strip a copyrighted music bed before reposting.

Why use these video tools
FFmpeg in the browser
The same encoder used by desktop video software, compiled to WebAssembly and running in the tab. Your file is never uploaded, so a 500 MB recording is not a 500 MB upload.
No watermark, no cap
Output is clean, at full resolution, with no branded overlay and no limit on how many clips you process. Nothing to unlock, because there is no server cost to recover.
Real control over the output
Choose a target bitrate or quality level, set exact trim points, and pick GIF frame rate and dimensions, rather than accepting one preset and hoping the size lands where you need it.
Frequently asked questions
Why is processing slower than other online video tools?
Because the encoding runs on your computer rather than on a rented server farm. A site that finishes faster is doing so on hardware you uploaded your file to. The trade is speed for privacy and no file-size limit — for a short clip the difference is seconds, and nothing ever leaves your machine.
Is there a file size limit?
No fixed limit, but browser memory is the practical ceiling. Files up to about 500 MB work reliably on a typical laptop. Above that, trimming first and then compressing the shorter clip is more dependable than doing both in one pass.
How much smaller will a compressed video be?
Typically 50–80% smaller with little visible difference, depending on the source. Screen recordings and phone footage compress especially well because they contain a lot of static or repeated frames. Already-optimised video will shrink less, since the redundancy has been removed once already.
