Video Compressor questions
Short answers, then the practical details.
Can I compress a video without uploading it?
Yes. The video is encoded on your device and Zipora does not upload it. No signup is required.
Will the video always get smaller?
Savings depend on the input. If an output is equal to or larger than your original, Zipora tells you to keep the original or try a smaller preset.
Which browsers and formats work?
Use desktop Chrome or Edge for broad support. The tool accepts supported MP4, WebM and MOV files up to 100 MB, five minutes and 4K resolution. Output is H.264 MP4 with AAC audio when the source has a compatible audio track.
