How to compress a video online

Three steps, no sign-up and no upload.

  1. 01

    Add your videos

    Drop videos anywhere on the page. Their length and size are read right away, and you can preview them before compressing.

  2. 02

    Choose the settings

    Pick a quality, a resolution, MP4 or WebM, and whether to keep the audio. Smaller resolutions save the most space.

  3. 03

    Compress, compare and download

    Follow the progress, switch between the original and the result at the same moment, then download one video or all of them.

Why use this video compressor

Built on Mediabunny, an open source media toolkit for the browser.

Hardware accelerated

Encoding uses your device's video encoder through WebCodecs, so it is much faster than software converters running in the browser.

Private by design

Videos never leave your device. There is no upload, no queue, no account and no watermark.

Convert while you compress

Read MP4, MOV, MKV and WebM, and save as MP4 (H.264) for compatibility or WebM (VP9) for the web.

No size limit

Since nothing is uploaded, there is no file size cap beyond what your device's memory can handle.
