How do I make a video small enough for Discord?

Open it here, choose 8 MB or 10 MB under Compress and press the button. The bitrate and picture size are set so the file lands just under that size; a very long video will come out soft at that size, so trimming it to the part that matters gives a sharper result.

How do I convert MP4 to MP3?

Open the video, choose Audio, pick MP3 and a bitrate - 192 kb/s is plenty for speech and most music - and press Extract audio. Only the soundtrack is kept, and it takes a second or two even for a long video.

Will the video have a watermark?

No. There is no watermark, no length limit and no account - the video is processed by your own browser and nothing is added to it.

Why can it not open my AVI or WMV file?

Those formats and their codecs are not built into web browsers, and this works with what the browser can decode. Most phones, cameras and screen recorders use MP4 or MOV, which open here; an old AVI can be converted with a desktop program such as HandBrake.

About this video compressor

Discord caps free uploads at 10 MB, email at about 25 MB, and a phone records a minute of video at far more than either. Pick the size the video has to fit and this works out the rest: the bitrate that size allows over the video’s length, and a picture size that bitrate can carry without turning to mush - so a short clip stays sharp at full HD and a long one drops to 720p rather than falling apart. Trim it first if only part of it matters; a shorter video can keep more quality in the same space.

Convert changes the format instead - MP4 plays everywhere, WebM suits websites, MOV suits Apple apps - with a choice of size and quality. Audio pulls the soundtrack out as MP3, M4A or WAV, and GIF turns up to twenty seconds into an animation. The encoding is done by your browser’s own video encoder, usually on the graphics chip, so a minute of 1080p takes seconds rather than minutes. It is free to use, with no account and no upload limit, and it runs entirely in your browser: nothing is uploaded, and it keeps working offline once it has loaded.

Opens: MP4, MOV, M4V, WebM and MKV video in H.264, VP8, VP9 and AV1 - and H.265 (HEVC) where the browser decodes it, which most do on Apple devices and recent Windows PCs - plus MP3, M4A, WAV, OGG and FLAC audio. Not older formats such as AVI, WMV and FLV. Saves MP4, WebM, MOV, MP3, M4A, WAV and GIF.
