Compress a video to 8 MB.

Eight megabytes is a common ceiling for forums, older chat servers, form uploads and ticket systems. Drop your clip in with 8 MB selected and get an MP4 that is under the limit.

The 8 MB target is already selected. The result is never larger than 8 MB: if the first try is over, it is encoded again.

Drop a video to compress

MP4, MOV, WebM or MKV. The file is read inside this page and goes nowhere else.

No upload. This page's security policy forbids network connections, so your video cannot leave it. See how to check that yourself.

Plainsum Video Pro

Pro is a one-time $19. It takes input files of any size (free stops at 500 MB), compresses a queue of files one after another, asks the browser for the hardware video encoder first, and remembers your settings.

After you pay, Creem emails you a license key. You paste it on the activation page, which is the only page that talks to a server. Compressing a video never does.

How it works

1

Drop in the video

Nothing is uploaded. The browser opens the file from your disk and reads the length, size and codecs.

2

Choose the size

Pick a preset or type your own. The plan line tells you the picture size and bitrate it will use, or that the target cannot work.

3

Compress and check

Watch the progress, play the preview, and download. If the first try is too big it is re-encoded at a lower bitrate.

Getting the best 8 MB video

  1. Trim first. Every second you cut is space the rest can use. Type start and end times in the Trim boxes, such as 0:12 and 0:45.
  2. Drop the sound if it does not matter. At 8 MB the sound can take a visible slice of the budget.
  3. Screen recordings compress well. A recording of an app or a game menu, where most of the picture stays still, looks far better at 8 MB than a clip of fast camera movement.
  4. Read the plan line. It shows the picture size the tool will use before you start. If it says the picture will be rough, trim or raise the target.

How much video fits in 8 MB

A file's size is its bitrate multiplied by its length, so the only things that decide whether a clip fits are how long it is and how much of the budget goes to picture and sound. This table shows what the compressor on this page picks for a 1080p, 30 frames per second clip with sound. It is worked out with the same planning code the tool runs, so it is a good guide to what you will get. How sharp a particular clip looks also depends on how much moves in it.

Questions

How long a video can I fit in 8 MB?

That depends on the picture size you accept. The table on this page shows what the compressor picks for common lengths. As a rough guide, a minute of video with sound fits at a small, clean picture size, and ten minutes only fits as a very small, soft picture.

Is 8 MB megabytes or mebibytes?

The tool counts in decimal megabytes: 1 MB is 1,000,000 bytes, which is how upload limits and most file managers count. Your file will also be under 8 MiB (8,388,608 bytes).

The result is smaller than 8 MB. Why?

The tool aims a little under the target so the file reliably fits, and it will not add quality that the original does not have. If your source is already low bitrate, the compressed file can be well under 8 MB.

Why did it say the video does not fit?

At 8 MB there is a floor under which a picture is not worth making. If your clip is longer than the target can hold, the tool tells you about how much length fits. Trim the clip, remove the sound to win back a little, or choose a larger target.

Will the sound be kept?

Yes by default, at a bitrate the tool picks from the budget (lower when space is very tight). Choose "Remove audio" to give all the space to the picture.

Can I compress more than one video at once?

The free version does one at a time. Pro adds a queue that compresses several files in turn, each to its own 8 MB budget.
