How do I compress a video to 25 MB?

Drop the video onto the compressor above. 25 MB is already set as the target (you can switch to another size or a percentage), so click Compress and download the result.

Which video formats can I compress to 25 MB?

MP4, MOV, MKV, WebM and AVI. Each file keeps its own format.

Which format should I use for a 25 MB video?

MP4 is the safest choice: it plays on every phone, browser and chat app. WebM is as efficient but less widely accepted. Compressing keeps each file's format, so convert first if the destination needs MP4.

How much quality will I lose at 25 MB?

25 MB holds a couple of minutes at good quality. Email attachments grow by about a third when encoded for sending, so a file right at the limit may still bounce. A 3-minute clip at 25 MB gets about 1.1 Mbps for video and audio together (720p). Each file keeps its own format.

What if my video won't fit in 25 MB?

Trim to the part that matters: length is the biggest lever. At 25 MB, a 1-minute clip gets about 3.3 Mbps (1080p or 720p); trimmed to 30 seconds it gets 6.7 Mbps (1080p, high quality). 720p is plenty on a phone: 720p has less than half the pixels of 1080p, so the same bitrate looks much cleaner. Most people watch shared clips on a phone anyway. Screen recordings fit more: slides, code and app UI barely change between frames, so a screen recording stays sharp at 25 MB for far longer than camera footage.

Will the file be exactly 25 MB?

It aims to land at or just under 25 MB. 25 MB here means 25,000,000 bytes, so it also fits sites that count 1 MB as 1,048,576 bytes.

What is 25 MB typically needed for?

Common reasons: many email providers cap attachments around 20–25 MB; learning platforms and assignment portals; chat apps with larger upload limits. Limits vary by site, so check the exact number where you're uploading.

Are my videos uploaded?

Every video format here is compressed in your browser, so nothing is uploaded.

What fits in 25 MB

Any video at 25 MB has the same bit budget, whatever the format: the longer the clip, the lower the bitrate and resolution it can keep.

Clip length	Video + audio bitrate	Realistic quality
1 min	3.3 Mbps	1080p or 720p
3 min	1.1 Mbps	720p
5 min	667 kbps	480p
10 min	333 kbps	360p, fine on a phone
30 min	111 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.

Video won't fit in 25 MB?

Trim to the part that matters
Length is the biggest lever. At 25 MB, a 1-minute clip gets about 3.3 Mbps (1080p or 720p); trimmed to 30 seconds it gets 6.7 Mbps (1080p, high quality).
720p is plenty on a phone
720p has less than half the pixels of 1080p, so the same bitrate looks much cleaner. Most people watch shared clips on a phone anyway.
Screen recordings fit more
Slides, code and app UI barely change between frames, so a screen recording stays sharp at 25 MB for far longer than camera footage.
Emailing it? Aim a little lower
Attachments grow by about a third when they're encoded for email, so a file right at an email limit can still bounce.
