How do I compress an MP4 to 5 MB?

Drop the MP4 onto the compressor above. The 5 MB target is already set, so just click Compress and download the result.

Will the file be exactly 5 MB?

It aims to land at or just under 5 MB. 5 MB here means 5,000,000 bytes, so it also fits sites that count 1 MB as 1,048,576 bytes.

How much quality will I lose at 5 MB?

5 MB suits clips of up to a minute or so; anything longer gets low resolution, so trim it first if you can. For a 1-minute clip, 5 MB leaves about 667 kbps for video and audio together (480p); a 3-minute clip gets 222 kbps (240p, low quality).

My MP4 is already smaller than 5 MB. What now?

Then it already fits, and compressing it further would only cost quality. Upload it as it is, or pick a smaller target if you need it smaller still.

What if my MP4 can't get down to 5 MB?

If a video is too long for 5 MB, the quality would drop too far. Trim it to the part you need, or pick a larger size.

What is 5 MB typically needed for?

Common reasons: short clips attached to emails; video uploads on forms and support tickets; previews and teasers. Limits vary by site, so check the exact number where you're uploading.

Yes. It's compressed inside your browser and never uploaded.

What fits in 5 MB

A 5 MB file has a fixed bit budget, so the longer the clip, the lower the bitrate and resolution it can have.

Clip length	Video + audio bitrate	Realistic quality
15 s	2.7 Mbps	1080p or 720p
30 s	1.3 Mbps	720p
1 min	667 kbps	480p
2 min	333 kbps	360p, fine on a phone
5 min	133 kbps	Too low: trim the clip

Rough guide for H.264-class video. Static scenes and screen recordings look better than fast action at the same bitrate.

What 5 MB is typically for

Short clips attached to emails
Video uploads on forms and support tickets
Previews and teasers

Limits vary by site and change over time; check the exact number where you're uploading.

How MP4 gets smaller

Re-encodes the video at a lower bitrate (and resolution on Strong); audio is re-encoded to AAC.
