Compress Video to 8MB
Prepare a short MP4 for a form, support ticket, or older system with an 8MB ceiling. The browser encodes the delivery copy on your device, so you can judge whether the small byte budget still carries the detail you need.
Delivery ceiling
8MB
Use this target only when the receiving form or system actually imposes a very small file allowance.
Working margin
7.5MB
Aim below the stated cap because target-size encoding is an estimate and some workflows count more than the video alone.
Output copy
H.264 MP4
The download uses H.264 video and optional AAC audio in MP4; keep the larger source for editing or evidence.

What an 8MB target can realistically carry
Eight megabytes is a narrow delivery envelope rather than a sensible archive size. It favors a concise answer, proof clip, or low-motion screen capture and becomes much less forgiving as runtime grows.
Give a brief clip a fair budget
With 128 kbit/s audio, the target formula estimates about 990 kbit/s of video for 1 minute. That can suit a focused explanation better than trying to fit several minutes into the same space.
Recognize the long-clip floor
At 3 or 5 minutes, the calculator reaches its 250 kbit/s minimum video rate with 128 kbit/s audio. The result may still exceed 8MB, and forcing more content into the target would make detail fragile.
Trade dimensions before legibility
For longer material, try 480p, reduce frame rate when motion allows, mute unnecessary audio, or shorten the clip instead of preserving a large frame at too few bits.
Make a local throwaway copy
The browser processes the source on-device. Treat the 8MB MP4 as a submission copy and retain the original wherever quality, captions, or later editing matter.
How to prepare a video under 8MB
Remove avoidable runtime first, then spend the remaining bytes on the information the recipient must see and hear.
Choose the shortest useful clip
Add a focused source after trimming pauses or unrelated footage when possible. The file is read locally by the browser.
Enter a target below 8MB
Use Basic mode for a quick estimate and leave margin below the receiver's hard cap rather than expecting an exact 8MB result.
Simplify the picture and sound
Open Advanced mode for 480p, a lower frame rate, 64-128 kbit/s audio, or no audio. Preserve more resources when text, speech, or motion carries evidence.
Measure and watch the MP4
Confirm the downloaded size, review the busiest scene and all important speech, then upload only after the copy fits and remains understandable.
8MB video compression questions
Practical limits for a target that leaves little room for long runtimes or complex motion.
8MB FAQ
Is 8MB enough for a one-minute video?
It can be for simple footage. With 128 kbit/s audio, the estimator allocates about 990 kbit/s to one minute of video, but fast motion, small text, and noisy scenes may still need a larger file.
8MB FAQ
Why can a long result miss the 8MB target?
The size control estimates bitrate and the encoder keeps video at or above a 250 kbit/s floor. At 3 or 5 minutes with 128 kbit/s audio, that floor can spend more data than an 8MB target allows.
8MB FAQ
Should I target exactly 8MB?
No. Final size varies with the encode, and a receiving system may measure limits differently. Use a lower working target such as 7.5MB and check the actual download.
8MB FAQ
What should I change when text becomes unreadable?
Shorten the clip or allow a larger file first. You can also reduce dimensions so the available bitrate is not spread across unnecessary pixels, but always inspect the text at its intended viewing size.
8MB FAQ
Does my source video leave the device?
No. Compression runs locally in the browser and produces an MP4 download on the same device; the source is not sent to a file-processing server in this flow.
