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. To trim, cut out or join without re-encoding at all, so the quality is untouched and it takes seconds, use the Video Cutter. It is free to use, with no account and no upload limit, and it runs entirely in your browser: nothing is uploaded, and while the page stays open, a feature you have already used keeps working offline.
- How do I convert MTS or M2TS camcorder video to MP4?
- Drop the .mts or .m2ts file here - the AVCHD files Sony, Panasonic and Canon camcorders save in a PRIVATE/AVCHD folder - and choose Convert to MP4. The page decodes it with FFmpeg in your browser, deinterlaces it, turns the Dolby sound most camcorders record into AAC, and makes an H.264 MP4 that plays on any phone, TV or computer; then it can be compressed or trimmed here like any other video. Nothing is uploaded, however large the file.
- How do I make a video small enough for Discord?
- Open it here, choose 8 MB under Compress and press the button. Discord’s free limit is 10 MB; aiming at 8 leaves a margin. The bitrate and picture size are set for the file to land just under the size you pick, and the result is checked: if it comes out more than a few per cent over, it is encoded again a little smaller, and if it is still over, the page says so. 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, re-encoded as MP3 in your browser.
- 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.
- How do I convert AVI, WMV, FLV or VOB to MP4?
- Drop the file in. Browsers cannot play these older formats, so the page says what the file is - say an AVI with Xvid video, or a DVD's interlaced MPEG-2 - and offers to convert it to MP4 first. FFmpeg, the open-source media library, built for this site, decodes the old video a few seconds at a time, and your browser's own encoder makes the H.264, so it is quick. DVD and camcorder video is deinterlaced and widened to the shape it is shown at. The MP4 then opens here like any other video, to shrink, trim, turn into a GIF or save the sound as MP3 - or just save it. Windows Media, RealAudio, AMR and AC-3 sound works the same way, as M4A.
