How it works
Choose compression
Pick Light, Balanced, or Strong and optionally limit resolution without upscaling.
Download the MP4
Compare the real file sizes, preview the result, and download it.
Smaller videos with practical defaults
The presets adjust H.264 quality and audio bitrate rather than promising an exact output size. Balanced is a practical default; Strong trades more visual quality for a smaller file, while Light preserves more detail.
Already-efficient or extremely short videos can become larger after re-encoding. The result panel reports the actual difference honestly and keeps a valid output available for download.
Frequently asked questions
How can I make a video file smaller?
Choose a stronger compression level or a lower maximum resolution. The tool never upscales a source that is already smaller than your selected limit.
Does compressing reduce video quality?
Yes. Video compression exchanges some detail for a smaller file. Light retains more quality; Strong removes more data.
Is my video uploaded?
No. FFmpeg.wasm processes the selected file inside your browser, and the application has no media upload endpoint.
What video formats can I compress?
The interface accepts MP4, MOV, and WebM containers. Success still depends on whether the included FFmpeg build can decode the codecs inside.
