- 3
Watch the meter
The estimate updates live and warns you if the size is too small for the length.
- 4
Export
The bitrate is worked out so the file lands just under your limit.
Popular ways to use it
Send on WhatsApp
Get a long clip under 16 MB so it sends as a video, not a blurry preview.
Email attachments
Fit a product demo or a class assignment under the 25 MB attachment limit.
Discord clips
Squeeze a highlight under 10 MB for servers without Nitro.
Free up storage
Turn 4K phone videos into sharp 1080p files at a fraction of the size.
Tips for the best result
- If the meter turns amber, choose 720p — a smaller picture at a healthy bitrate looks better than a big blurry one.
- Trimming away the parts you don't need is the easiest way to keep quality high under a tight limit.
- "Balanced" quality is a good default when you just want a smaller file without a specific limit.
Compress / fit a size — FAQ
How do I make a video smaller than 16 MB for WhatsApp?
Choose "Fit a size" and tap WhatsApp. The bitrate is calculated so the file lands just under 16 MB, and the meter tells you in advance.
What if my video is too long to fit?
The meter warns you when a size would make the picture blurry. Trim the video or lower the resolution to 720p for a sharper result.
Does compressing reduce quality?
A little, by design — the file gets smaller by using fewer bits. At sensible sizes the difference is hard to see on a phone screen.
Can I compress several videos at once?
One at a time. After exporting, use "Same edits on the next video" to repeat your settings in one tap.
Which format should I choose?
MP4 plays everywhere. WebM is a little smaller but not every phone and app can play it.
