How it works

Does my video get uploaded anywhere?

No. All processing runs inside your browser. Nothing leaves your device.

Does changing speed affect audio pitch?

Yes — speeding up raises the pitch and slowing down lowers it, like a traditional tape speed change. This tool does not apply pitch correction.

Which formats are supported?

MP4 (H.264) and WebM (VP8/VP9) work in most modern browsers. Less common codecs may not be supported, and the tool will say so.

Why does the output duration differ slightly from the estimate?

The estimate is based on the file's reported duration. The actual encoded output may differ by a frame or two due to codec rounding.

Grab a still image from any moment in a video and save it as a PNG, JPEG or WebP.

Change a video's container format and codec — pick MP4 or WebM and the quality level that suits your needs.

Reduce a video's file size by targeting a lower bitrate and, optionally, a smaller frame size — and see exactly how many bytes you saved.

Spin a video 90°, 180°, or 270° — uses lossless metadata when the container supports it.

Mirror a video horizontally or vertically to correct its orientation or create a reflection effect.

Strip the audio track from a video file and keep the picture exactly as it is.

Turn a section of any video into an animated GIF, with control over frame rate, output size and colour depth.

Convert an animated GIF to an MP4 video — usually far smaller than the source GIF and compatible everywhere.
