About this Compress Video tool
Phone videos are huge: a single minute of 4K footage can be several hundred megabytes. That is too big for WhatsApp, email attachments, Discord or many upload forms.
This compressor re-encodes the video with your device's own hardware encoder, lowers the bitrate and, if you want, the resolution. You can also type an exact target size such as 16 MB and the tool works out the right bitrate for you.
