Email Attachment Size Limits
Most email providers limit attachments to 20-25MB. Gmail allows 25MB, Outlook 20MB, and most corporate email even less. Videos routinely exceed these limits.
Compressing video for email requires aggressive settings. The goal is small file size first, acceptable quality second. Recipients can request the original if needed.
This tool compresses video in your browser without uploading. Your private videos stay private, unlike cloud compression services.
Recommended Email Video Settings
Resolution: 720p maximum. This provides good quality on phones and laptops while keeping file size manageable.
Preset: "Fast" for maximum compression. Quality trade-off is acceptable for email sharing where recipients expect smaller files.
Frame rate: 24fps is sufficient for most content. Higher frame rates significantly increase file size without noticeable benefit at 720p.
Alternative Sharing Methods
For videos that cannot be compressed enough, consider cloud sharing links from Google Drive, Dropbox, or OneDrive.
YouTube unlisted videos work well for sharing longer content. Recipients can view without the video being public.
Split long videos into multiple parts if email is the only option. Each part can meet the size limit individually.
Video to MP4 FAQs
What is the email attachment size limit?
Gmail allows 25MB, Outlook allows 20MB, Yahoo allows 25MB. For safety, aim for under 20MB to ensure delivery across all providers.
How do I get my video under 25MB?
Use 720p resolution, "Fast" preset, and reduce frame rate to 24fps. For longer videos, you may need to go to 480p or split into parts.
Will the compressed video look okay?
At 720p with reasonable compression, quality is good for typical viewing. Recipients can watch on phones or small screens without issues.
What if my video is still too large?
Reduce resolution to 480p, use "Fast" preset, or trim the video to a shorter duration. Each change reduces file size.
Can I compress 4K video for email?
Yes, but you will need to reduce resolution to 720p or lower to meet email size limits. 4K at low bitrate does not look good anyway.
Is my video kept private?
Yes. Video compression happens entirely in your browser. Nothing is uploaded to any server. Your content remains completely private.
