Video Tools

With video, "nothing is uploaded" stops being a slogan and becomes the whole reason. A three-minute phone clip is 200 to 400 MB; other sites ask you to push that up your home connection before they will look at it, then pull it back down. The tools in this category read the file where it already is — on your machine — using the browser's own WebCodecs interface, which means the same hardware encoder your phone or graphics card uses when recording.

Several jobs do not need re-encoding at all. A phone's sensor always shoots landscape; holding the phone upright does not rotate a single pixel, it writes a small matrix into the file that tells the player to turn it on playback. A video that plays sideways usually lost that matrix somewhere along the way — rotate writes it back in a fraction of a second, whatever the file size. Remove audio and to MP3 likewise copy the stream they keep instead of decoding it.

Trim cuts a clip to a range, grab a frame saves any moment as a JPG or PNG, and compress shrinks a file to a quality level or a target size in MB, showing the expected result before you start. Because everything runs on your device, a 2 GB recording costs nothing extra; the limits are your browser's codec support, and each tool page says what happens on Safari or on a machine without an HEVC decoder.
