At a glance
| Situation | Best choice | Why |
|---|---|---|
| Short clip under 1 minute | Under 25 MB, keep resolution | Fits standard email limits while keeping original sharpness |
| Longer video (2–5 minutes) | Under 25 MB + 720p or 480p | Lower resolution prevents heavy blur at small file sizes |
| Silent demo or screen recording | Under 25 MB + Remove sound | Stripping audio frees up space for clearer video |
Related questions
How do I compress a video to 25 MB?
Open the tool on this page, load your video, and set the Goal to Under 25 MB. The encoder automatically adjusts the bitrate so the final MP4 stays below that limit.
Is my video uploaded to a server when I compress it?
No. Compression runs locally in your browser using your device's built-in WebCodecs encoder, so your file never leaves your computer or phone.
What if my video is still too blurry at 25 MB?
Long videos packed into 25 MB can lose detail. Try lowering the Resolution to 720p or 480p, or share a cloud link if the clip is very long.
Which browsers work for compressing email videos?
Recent versions of Chrome, Edge, and Safari on iPhone or Mac, as well as Firefox on desktop computers.
