WhatsApp's 16MB Video File Size Limit

If you choose to send an existing share-worthy video in WhatsApp, you'll be prompted to trim the video to under 16MB on mobile phones, but it will pop up a message saying "1 video you tried adding is larger than the 16 MB limit" on both PC and Web apps. It's not strange to see that, after all, WhatsApp is just a messaging app and isn't really meant to be a file or video hosting service.

Therefore, how to compress video files to 16MB is always a very hot topic amongst WhatsApp users. That's the main reason I've compiled this tutorial. In the following content, I'll introduce four simple applications and guide you through the steps to make video less than 16MB for sending in WhatsApp.

Step 3 - Choose One Plan to Make Video Less than 16MB

Plan A. Lower Video Bit Rates

As the bit rate mainly determines the video quality and file size, a direct way to resize video files to 16MB by decreasing the video bit rates. But meanwhile, the video quality will be degraded as well. You have to keep the balance between the video quality and file size. The app offers two ways to lower video bitrate:

1. Batch Compression Bar

Click on "Batch compression" icon on the bottom of the program to activate the feature. Once the icon becomes orange, move the slider towards the right side to increase the compression ratio to batch compress videos to 16MB. The higher the compression ratio, the smaller the file size and the worse the video quality.

2. Manually Reduce Video Bitrate

Click on "Parameter settings" button underneath the "Output Format" image to open a window. Navigate to "Video Bit rate" section and choose a pre-set option in the drop-down list, or press "Customize" button to manually type in a lower value to reduce video bitrate. Click OK to save the changes.

Plan B. Downscale Video Resolution

You're recommended to downscale video resolution to 720p or lower from the "Quick setting" section. Alternatively, open "Parameter settings" to change video resolution to a lower value.

Note: The resolution doesn't determine the video quality and file size. But a video with higher resolution generally has a better quality with large file size, because cameras always record video at a higher bit rate for the larger resolution.

Plan C. Trim Desired Video Clips

This app allows you to split the large-sized video files into multiple small video clips under 16MB. Press the "Scissors-shaped" icon on the editing toolbar to open "Trim" window. Drag the two sliders along the playback progress bar to select a desired video segment, or type in the accurate start time and end time, then press "Trim" button to cut a video clip below. Repeat the process to get multiple small video clips.
