Best video compressor for mac to reduce the file size of video?

Large video attachments can easily exceed an email provider’s file-size limit, especially when the original recording uses a high resolution or bitrate. For users who need to compress a video on mac for emai, HandBrake can re-encode the video with a smaller resolution, bitrate, or quality level while letting you preview the result before sharing it.

How to compress a video on mac for emai

Step 1: Open the program on your Mac and click Open Source. Select the video you want to reduce, then wait for it to scan the file and display the video information.

Step 2: Open the Preset menu and choose a suitable preset. For an email attachment, a lower-resolution preset such as Fast 720p30 can significantly reduce the file size compared with keeping a large 1080p or 4K source.

Step 3: In the Summary tab, choose MP4 as the output format for broad compatibility. Review the displayed video, audio, and subtitle information before continuing.

Step 4: Open the Video tab and make sure a common codec such as H.264 is selected. Use the Constant Quality control to adjust compression; moving toward a higher RF value generally produces a smaller file but also reduces image quality, so make changes gradually.

Step 5: Open the Audio tab and check the audio track. Lowering an unnecessarily high audio bitrate can save additional space, particularly for videos that mainly contain speech.

Step 6: Choose where the compressed file will be saved and enter an output filename. Click Start Encode and wait for the encoding process to finish.

Step 7: Check the size of the newly created video in Finder and play it to verify the picture and sound quality. If it is still too large for your email provider’s attachment limit, encode it again using a lower-resolution preset or slightly stronger compression.

Reducing resolution and bitrate usually makes the biggest difference when preparing a large video for email. It is better to compress gradually and check the result rather than immediately using very aggressive settings, which can unnecessarily reduce video quality.
