Video Compressor FAQs
It depends on the source, but Balanced typically cuts a phone recording to roughly a third of its size with no visible difference on screens. Smallest goes further for sharing on WhatsApp and messaging apps.
About this tool
A one-minute phone video can be 100 MB or more — too big for WhatsApp, too slow to email, and too heavy for forms with upload limits. Video Compressor shrinks it in your browser, with no upload and no account. Choose High quality to keep near-original detail, Balanced for the best size-to-quality trade-off, or Smallest file when you just need something that sends. The tool re-encodes with the widely compatible H.264 codec and AAC audio, so the result plays everywhere the original did. Because it runs locally, your private videos stay private — nothing is sent to a server, and there is no queue, watermark or limit on how many videos you compress. The only real cost is time: video encoding is heavy work, so a long clip on a modest device takes a few minutes, and the video engine downloads once (about 24 MB) before the first run. For everyone tired of 'file too large' errors, it is the free fix that works entirely on your own machine.
