What video formats are supported?

Currently, this tool only supports MP4 files. Other formats like MOV, AVI, or MKV will need to be converted to MP4 first.

Will compression reduce video quality?

Some quality reduction is inevitable when compressing video files, but our tool uses optimized settings to minimize visible quality loss while achieving significant file size reduction.

Is there a file size limit?

The tool can handle files up to 500MB. For larger files, consider compressing in segments or using desktop software.

How long does compression take?
