Compress Video for Email

Prepare a video before attaching it

Email attachment limits vary, and a video that plays perfectly on your computer may be too large to send. Compressing the clip first can make the file easier to attach, upload, or share from a phone. This tool accepts MP4, MOV, and WebM files up to 100 MB and three minutes, then returns an MP4. Always check the output against your email provider's actual limit before composing the message.

A smaller file also takes less time for recipients to download, which matters when they are using mobile data. Yet an attachment is not always the best delivery method. If a video is lengthy or the message system has a low cap, a shared file link may preserve quality better than aggressive compression. Use the tool when a shorter clip can be made suitably compact without spoiling the content.

How to use the compressor

1. Check the email limit

   Find the attachment cap for your provider or workplace system. Upload a supported source under the tool's 100 MB and three-minute limits. If your clip is too long, trim it to the part the recipient actually needs.

2. Compress with that limit in mind

   Start with Balanced for a reasonable tradeoff. Select Smaller file size if the first result exceeds the attachment cap. For a video with on-screen text or demonstrations, Better quality may keep the message clearer.

3. Attach the downloaded MP4

   Compare the reported size with the email limit. Download the MP4 and play it once before attaching it. If it still cannot fit, use a file-sharing link rather than degrading the video until it is hard to understand.

Email has its own practical limits

An email service may restrict either each attachment or the entire message. Some systems also encode attachments for transport, increasing the message size beyond the file shown on disk. That is why leaving margin below the published cap can help. A video file compressor cannot guarantee that a provider will accept every file; it only provides a smaller MP4 you can evaluate before sending.

If you are sending a presentation clip, trim the lead-in and ending before compression. Less footage can reduce megabytes while keeping each remaining frame clearer. For a simple personal message, a lower file size may be worth a little softness. The MP4 Compressor page is useful when your source is already MP4, and the 25 MB guide explains how to approach a common attachment threshold without promising an exact target.
