For example, how much you want to reduce? What is the best video compressor? How to compress videos for email attachments without losing quality? Let’s dive in and find the answers.

What Is the Maximum Size of an Email Attachment

Without exception, email servers refuse to accept large attachments. But the specific standard differs in different tools and platforms (email client and webmail). To make a proper compression, let’s take a look at the maximum video attachments size, which also should be the target file size for your large video:

How to Compress a Video for Email

Since you may have different needs for the compression ratio and the video quality in various situations, we summed up multiple methods including compressing MP4/AVI/WMV videos using VideoProc, zipping programs, online compressors, and cloud services, among which we recommend VideoProc most for its all-in-one solutions. Let’s have a look one by one.

Compress a video for Email with VideoProc

VideoProc is a simple yet powerful desktop program that also functions as professional video compression software. Most notably, it can reduce the file size to over 50% with the least quality loss by re-encoding with HEVC. For further size shrinking, it lets you lower the resolution, frame rate, and bitrate within a reasonable range.

In total, VideoProc supports 370+ input and 420+ output formats. So feel free to compress MP4, AVI, MKV, WMV, 4K, 3D, VR, and any large video files for email. With its advanced full-GPU acceleration tech, the compression speed can reach up to 47x real-time faster while keeping low CPU usage.

Here’s how to use VideoProc to compress videos to a file size accepted by Gmail.

  • Open VideoProc and choose the Video option on its homepage.
  • Drag the video you want to send via email into VideoProc. You can proceed to load more video files if necessary.
  • Click Video at the bottom side and choose MP4 HEVC as the output format.
  • Hit the Codec Option icon to open the customizable settings tab.
  • Downsize the video by choosing a lower frame rate, resolution, and bit rate.
  • When you see the estimated size is smaller than 25MB, click Done to save the changes.
  • Browse a folder to save the video. Click the RUN button to export the video.


Make a Video Shorter and Smaller

Another easy method is to cut your video into a shorter clip if it is too long to be compressed to 25MB. At the moment, VideoProc works as the best video editor to cut your large video file into a shorter one without rendering or quality loss.

VideoProc has 3 cutting modes – cutting out any part of the video, trimming off starting and end parts, splitting a video into several clips evenly. All of them can be easily found out in the editing toolbar and the toolbox at the bottom. Here we take the general cut mode as an example.

  • Import the video you want to send by Gmail or any other email to VideoProc.
  • Choose a target video format. MP4 HEVC and MP4 H.264 are both okay.
  • Click the scissor icon on the editing toolbar.
  • Drag the green knobs to specify the starting and end time of your video clip. Click Cut.
  • If you want multiple separated parts in your long video, repeat the step above to cut out more clips.
  • Click Done to get back to the main UI.
  • Select a destination folder to save the video.
  • If you have cut more than one clip, check the merge option on the right side.
  • Hit the RUN button to export the video.


Zip a Video File to Email

Mac and Windows computers both have built-in zipping programs in which you can make videos smaller and more convenient to transfer via email. Desktop zipping utilities have decent algorithms to reach a compression ratio of around 30%. But if you zipped a video file larger than 4GB on Windows, while the email recipient is using macOS, the zip file will fail to be opened on the Mac.

On Windows:

  • Right-click on the video or a video folder.
  • Choose Send to and Compressed (zipped) folder.
  • A new zipped folder with the same name in the same path is created.

On Mac:

  • Press and hold the control key, then click the video or a video folder you want to zip.
  • Select Compress [file name] or Compress x Items from the shortcut menu.
  • The video will be compressed with a .zip extension, while the folder with
