    Shrinking a file to send it?

    Studio takes recordings up to 2 GB on the free plan, so you can send the original and get back the finished edit.

    How to make a video file smaller

    1. Add your videoIts size, length and frame size show under the preview.
    2. Choose how to compressQuality level lets the encoder decide the size. Target file size takes a number of megabytes and works out the bitrate to hit it.
    3. Set the resolution if you wantDropping from 1080p to 720p saves more than any quality setting. Leave it on Keep and the target-size mode picks one for you when the budget is tight.
    4. Compress and compareThe result shows both sizes and the percentage saved. Play it before you delete your original.

    Getting a good result

    How target size works

    A file's size is its length multiplied by its bitrate. The tool divides your target by the length of the video, takes off what the sound needs, and encodes the picture twice: the first pass measures which moments are hard to compress, the second spends the bits there. The result lands under your number. If the budget is too small to look acceptable at the original frame size, it steps down to 720p, 480p or 360p instead of filling the picture with blocks.

    Which quality level

    High is hard to tell from the original. Balanced is right for most sharing. Smaller and Smallest show softness in hair, grass and fast movement, and make small text on a screen recording harder to read. For screen recordings, lower the resolution less and the quality less; for a talking head, a lower resolution usually costs little.

    When the file does not get smaller

    A video from a messaging app or a previous compression is already squeezed hard. Re-encoding it at a gentler setting can come out larger. The tool tells you when that happens. Keep your original, or choose a smaller target or a lower resolution.

    00:40Questions

    Video compressor: common questions

    How small can I make a video?

    The picture needs at least about 90 kilobits a second to be watchable, so a 2-minute video cannot go much below 2 MB. The tool tells you when a target is too small for the length.

    What target should I use for email?

    Gmail stops attachments at 25 MB, and the encoding that email uses adds about a third to a file on the way. Aim for 18 MB or less, or send a link instead.

    Does it change the format?

    The result is always MP4 with H.264 video and AAC sound, whatever you upload.

    Is the sound compressed too?

    Yes, to AAC at 128 kbps, or 96 or 64 kbps when a small target leaves little room. Speech stays clear at all three.

    How long can the video be?

    Up to 5 minutes and 100 MB. Trim a longer recording first, or send it to Studio, whose free plan takes files up to 2 GB.

    Editing a talk, a podcast or an interview?

    Upload the raw recording. Studio cuts the ums, retakes and long pauses, adds captions and makes short clips. 30 free minutes, no card.
