Shrink any video to 25 MB or less to fit common 25 MB email attachment limits. MP4, MOV, WebM and MKV and more.

Accepted formats: MP4, MOV, MKV, WebM, AVI. API: `POST /api/v1/jobs` with `"operation": "compress", "target_size": "25mb"` (paid plans).

## How to compress a video to 25 MB

1. **Add your videos.** Drop MP4, MOV, WebM or MKV files onto the compressor above, paste them, or click to browse. Mixed formats are fine.
2. **25 MB is preset.** Every file is compressed to land at or just under 25 MB. You can switch to another size, or a percentage to reduce by.
3. **Compress.** Click Compress. Each video keeps its format and is processed right in your browser.
4. **Check and download.** Check the new sizes, then download each file or all of them as a ZIP.

## Good to know

- 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.
- 25 MB here means 25,000,000 bytes, a little under the 26,214,400 bytes some sites mean, so the result fits either way.
- 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._

## What 25 MB is typically for

- Many email providers cap attachments around 20–25 MB
- Learning platforms and assignment portals
- Chat apps with larger upload limits

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

## 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.

## Compress video to 25 MB: frequently asked questions

### 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.

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?
