Compress Video · client-side FFmpeg

FileForge is bringing FFmpeg entirely inside your browser tab — nothing uploads. Enable this tool by turning on cross-origin isolation in your deployment (see ffmpegwasm.netlify.app), or use the desktop CLI in the meantime.

About Compress Video

Shrink a video by lowering resolution and raising the CRF quality factor, re-encoded with x264 inside your browser. Great for getting a clip under an upload limit. Everything happens locally in your browser: nothing is uploaded, stored, or logged. This focused Compress Video page is designed for people reducing clips for email, chat, learning platforms, listings, and bandwidth-limited publishing. It opens directly to the working tool, rather than hiding the function inside a general converter or account dashboard.

A WebAssembly build of FFmpeg reads the media from browser memory, runs the selected codec operation on your CPU, and writes the result back to the tab. Your filename and file contents stay on the device. There is no upload queue, temporary cloud copy, account record, or server-side conversion job to delete later. That makes the tool practical for personal records, work material, and drafts that should not be handed to an unknown processing service.

The operation stays focused on reduce bitrate and resolution. You can inspect the result immediately and repeat the task with different settings without a quota or watermark. Processing speed and maximum size depend on your browser and available device memory, which is the honest trade-off for doing the work locally.

FileForge charges nothing for this tool and does not add a watermark. Once the page and its processing engine have loaded, the operation can continue without sending the file over the network. Use the numbered steps below, download the result, and review it before replacing an original file.
