FAQ
How do I shrink a video for messaging apps?
Lower quality or target a smaller size in the compressor, then check playback. Messaging apps often also re-encode on upload, so keep a master copy.
Will compression remove audio or crop the frame?
Standard compression reduces bitrate/size while aiming to keep the same picture and soundtrack. Use separate trim or crop tools if you need to cut content.
Why did compression fail on a long 4K file?
In-browser compression is limited by device memory and CPU. Try a shorter segment, lower resolution source, or a more powerful machine.
Is my data private?
After the local engine loads, compression runs on your device. Videos are not uploaded to our servers to shrink them.
