About

Some chat apps, forms and upload fields accept only files up to a set size. If the limit you face is 8 MB, the Video Compressor can get a clip under it. This page opens the tool already set to 8 MB, the Small messages option, so you do not have to find the right setting first.

At 8 MB the picture has little room for detail, so length and resolution matter most. A short clip with little movement keeps more detail than a long clip with fast action. Turning Keep sound off gives the picture more of the 8 MB. Choosing a smaller resolution can help a clip that does not need a sharp frame. The page warns you when 8 MB is too small for the length of the video.

If the file is still over 8 MB after the tool tries again, the page says so. Then you can choose a larger size if your upload allows it, turn sound off, or cut the video shorter before you compress it. Nothing is uploaded while you do this, so you can try as many times as you need.

Questions

How do I compress a video to 8 MB?

Open the tool, keep 8 MB selected under Settings, and click Compress to 8 MB. When it finishes, click Download. If the panel says the file could not reach 8 MB, turn sound off or shorten the video, then try again.

Will compressing to 8 MB ruin the quality?

It lowers the detail, and the effect depends on the length of the clip. A short clip with little movement keeps more detail than a long clip with fast action, which looks soft. The page warns you when 8 MB is very small for the length of the video.

Can I make a long video 8 MB?

Sometimes, at a lower picture quality. If the tool cannot reach 8 MB at that length, it says so. Turn sound off, pick a larger size if your upload allows it, or cut the video shorter.

Does turning off sound save much space?

It frees room for the picture, which matters most at small sizes and on a long clip. Keep sound on when the audio is part of what you are sharing.

Why do some uploads need 8 MB?

Some sites and apps set a file size cap for uploads, and 8 MB is one size they use. Check the rules on the site you are uploading to, since caps differ and can change.
