Every tool runs in your tab

Decoding, processing and writing all happen on this machine. Nothing is uploaded, nothing is queued, and nothing asks who you are.

Honest limits

Where these tools stop

Running locally is a real constraint as well as a feature. Worth knowing before you drop a 6 GB file in.

Browser
The video and audio tools need WebCodecs: Chrome, Edge, Opera, or recent desktop Firefox; Safari works for some operations and fails at others. The image tools run in any current browser.
File size
Everything is held in the tab, so memory is the ceiling. A few hundred megabytes of video is comfortable; multi-gigabyte 4K will usually exhaust the heap. Images above 40 megapixels are scaled down as they are decoded.
Speed
Your hardware sets the pace. Video re-encoding runs at roughly real time on a modern laptop, faster with hardware acceleration; a stream copy takes seconds. AVIF is the slow image format.
Output
Compress, trim and logo removal export H.264 MP4 where the browser can encode it, WebM otherwise, re-encoding audio at 96 kbps when it has to. Convert to MP4 and Extract audio copy streams untouched whenever the codecs allow, and say when they could not.

Missing a tool?

The roadmap is mostly requests. If a job keeps forcing you to upload a file somewhere, that is the kind of thing we build next.
