How small can I make my video file?
The amount of compression possible depends on the original video content. Videos with lots of motion or detail compress less than videos with static scenes. Most users see file size reductions of 40-70%.
Will compressing my video reduce its quality?
Some quality loss is inevitable with video compression, but our tool uses efficient codecs to minimize visible quality degradation. You can adjust the compression level to find your preferred balance.
What video formats are supported?
Video Compressor supports MP4, WEBM, and MOV input formats. The output is optimized MP4 for the best cross-platform compatibility.
Are there any watermarks on the output?
