Questions
How do I make a video fit under 25 MB, or 10 MB?
Choose “Fit under a size” and type the limit. The resolution is lowered only as much as it takes to still look clean at that size.
Why does it take a while?
Every frame is decoded and encoded again on your device. A computer is usually faster than the video plays; phones are slower. Keep this tab open until it finishes.
Does the sound get worse?
No. The sound is copied as it is, unless a tight size limit needs it smaller.
Are my files uploaded?
No. The tool runs inside your browser, and the page is blocked from sending data anywhere. You can check by turning off your internet connection: it keeps working.
