Want to send a video by email but find that the file is too large to upload? Most email services have attachment size limits. For example, Gmail typically limits attachments to 25 MB, while email services such as Outlook have similar restrictions. Therefore, compressing the video before sending it is a simple and effective solution. In this article, we'll show you how to compress a video for email, helping you reduce the file size while maintaining good video quality.

If you want to control the video size, format, resolution, and quality directly before sending it, using a professional video compression tool can be more convenient. Video Converter Ultimate is a video processing tool for Windows and Mac that lets you compress videos by adjusting parameters such as file size, format, resolution, and bitrate.
It supports a wide range of common video formats, allowing you to choose a suitable output file based on your email service's requirements.
What can Video Converter Ultimate do for you?
Here is how to compress large video files for email without losing quality:
01Download and install Video Converter Ultimate on your computer, then launch the program. Go to the "Video" section, select "Video Compressor", and click the "+" button to import the video you want to send via email.

02Adjust the compression settings, including file size, resolution, output format, and other parameters. You can lower the resolution, such as converting a 4K video to 1080p, to further reduce the file size. Use the "Preview" feature to check the compression effect before exporting.
03Choose a save location and click "Compress" to start processing. After compression, check the new file size and adjust the settings again if it still exceeds your email attachment limit.

If you do not want to install software, you can also use an online video compression tool. FreeConvert is an online video compressor that allows you to reduce video file size directly from your browser without installing software. You can compress a video and make it easier to send as an email attachment.
Note: Online video compressors require you to upload your video to a third-party service. Large videos may take longer to upload and process, and you should consider privacy risks before uploading personal or confidential videos.
Here is how to compress video for email attachment online via FreeConvert:
Step 1. Open FreeConvert Video Compressor in your browser and click "Choose Files" to upload the video you want to compress.
Step 2. After the video is uploaded, adjust the compression settings if needed, such as the target file size, video codec, and output format.
Step 3. Click "Compress Video" to start the process. Wait for FreeConvert to finish uploading and compressing your video.
Step 4. Preview the compressed video and download the file to your computer.
Step 5. Attach the compressed video to your email and check whether it meets the attachment size limit of your email service.

If the video is already relatively small and only slightly exceeds the email attachment limit, you can try putting the video into a ZIP file. ZIP is a common file compression format that can be created and opened directly on both Windows and Mac without installing additional software.
Step 1. Locate the video file you want to send via email on your Windows computer.
Step 2. Right-click the video file and select "Send to" > "Compressed (zipped) folder".
Step 3. Windows will create a ZIP file containing the video. You can rename the ZIP file if needed.
Step 4. Check the ZIP file size. If it is within your email attachment limit, attach it to your email and send it.

Step 1. Find the video file you want to compress on your Mac.
Step 2. Right-click the video file and select "Compress".
Step 3. macOS will create a ZIP file in the same folder with the video inside.
Step 4. Check the ZIP file size and attach the ZIP file to your email if it meets the attachment size requirements.

If the compressed video is still too large, you can upload it to a cloud storage service and share it via a link instead of attaching the video directly to your email. Common cloud storage options include Google Drive, OneDrive, and Dropbox.
Here is how to compress a video for free for email using Google Drive:
Step 1. Open Google Drive in your browser and sign in with your Google account.
Step 2. Click "New" > "File upload", then select the video file you want to share.

Step 3. Wait for the video to finish uploading. The upload time depends on the video size and your internet speed.
Step 4. Right-click the uploaded video and select "Share".
Step 5. Change the access settings to "Anyone with the link" if you want others to open the video without requesting permission.
Step 6. Click "Copy link" and paste the link into your email instead of attaching the video file directly.
Many videos that need to be sent via email are recorded directly on smartphones. Transferring the video to a computer before compressing it can make the process more complicated. Therefore, for videos recorded on a phone, you can use a video compression app directly on your mobile device.
Step 1. Download and install Video compressor - save space from the App Store, then open the app and select the video you want to compress from your iPhone album.
Step 2. Choose a compression mode and adjust the settings based on your needs. You can select the compression percentage in Normal mode or customize advanced settings such as video resolution, frame rate, and bitrate in Advanced mode.
Step 3. Tap the compress option to start reducing the video size. After compression, compare the original and compressed file sizes to check the result.
Step 4. Save the compressed video to your iPhone or share it directly through email. You can also delete the original video if you need to free up storage space.

Step 1. Download and install Video Compressor - Save Space from Google Play, then open the app and select the video you want to compress from your Android device.
Step 2. Choose a compression option based on your needs. You can select a target file size, such as reducing a large video to a smaller size suitable for email sharing, or use Smart Fit to automatically adjust the compression settings.
Step 3. Customize the compression settings if needed, including video resolution, bitrate, output format, and compression quality. Lowering the resolution or bitrate can further reduce the video size.
Step 4. Tap the compress button to start processing the video. Wait for the app to finish reducing the file size.
Step 5. Preview the compressed video and check the new file size. Save the video to your device or share it directly through email.

Q1. What is the attachment size limit for common email services?
Most email services have limits on attachment sizes. Common limits include:
Q2. What video format is best for email attachments?
MP4 with the H.264 codec is the best choice for email attachments because it offers wide compatibility across different devices, email clients, and media players. For better compatibility, use AAC audio with 128kbps stereo settings. Avoid newer codecs like HEVC or AV1, as some recipients may not have compatible players or devices to open these videos.
Q3. Does video compression reduce quality?
Yes, but the level of quality loss depends on the compression settings. If you significantly reduce the resolution, bitrate, or quality, the video file size will become much smaller, but some details may be lost. On the other hand, using moderate compression settings can usually provide a better balance between file size and video quality.
If the video is only for email sharing, you can first try slightly lowering the resolution and bitrate instead of immediately choosing the lowest quality settings.
That's all about how to compress video files for email. For users who want more control over video size and quality, Video Converter Ultimate is a practical option. Its Video Compressor lets you adjust the target size and other output settings, making it easier to prepare videos for email while maintaining an acceptable level of quality.
If you frequently need to compress video files for email attachments, especially large or high-resolution videos, using a dedicated video compressor can save time and give you more control than simply zipping the file.
