About ClipZap
Free video tools that run entirely in your browser. No upload required. No account needed. No catch.
What ClipZap is
ClipZap is a collection of video and image editing tools that run completely inside your web browser. You can compress videos, trim clips, convert between formats, change playback speed, extract audio, remove backgrounds, generate subtitles, and more — without installing anything and without sending your files to any server.
Every tool on ClipZap processes your media locally on your device. When you click a button, your file does not travel over the internet to a remote machine. It stays exactly where it is: on your phone, laptop, or desktop.
Why it was built
Most online video tools either charge a subscription fee, add a watermark to your output, require you to create an account, or upload your files to a server where they are processed and — depending on the service — potentially stored, analysed, or used for other purposes.
ClipZap was built to provide a genuinely free alternative that does not compromise on privacy. Simple video tasks like trimming a clip, muting a video before sharing it, or compressing a file to fit under WhatsApp's size limit should not require trusting a third-party server with your files. They can be done locally, in seconds, in any modern browser. So that is how ClipZap does them.
The technology
ClipZap's video tools are powered by ffmpeg.wasm, a WebAssembly build of ffmpeg — the widely used open-source multimedia framework. WebAssembly allows near-native performance code to run inside a browser tab, which makes it possible to run real video encoding and decoding on your device rather than on a server.
The AI-powered tools — background removal and subtitle generation — use machine learning models running via ONNX Runtime Web and Transformers.js. The subtitle generator uses OpenAI's Whisper speech recognition model, and the background remover uses a computer vision segmentation model. Both run entirely on your device. No API calls are made to external AI services.
The site is built with Next.js and deployed as a static web application. There is no backend server that handles your files at any point.
