Email Attachment Limits — What Each Provider Allows
Every email provider has a different attachment size limit. Here are the current limits you need to know.
| Provider | Attachment Limit | Recommended Video Size | Notes |
|---|---|---|---|
| Gmail | 25 MB | Under 20 MB | Files over 25MB are automatically shared via Google Drive link instead. |
| Outlook / Hotmail | 20 MB | Under 15 MB | Outlook may suggest OneDrive for larger files. Shared mailboxes may have lower limits. |
| Yahoo Mail | 25 MB | Under 20 MB | Attachments over 25MB are not supported. No cloud fallback. |
| Apple iCloud Mail | 20 MB | Under 15 MB | Mail Drop allows up to 5GB via temporary iCloud link (expires in 30 days). |
| ProtonMail | 25 MB | Under 20 MB | Encrypted attachments have slightly more overhead. Keep under 20MB to be safe. |
| Corporate Exchange | 10–25 MB | Under 10 MB | Varies by admin setting. Many organizations cap at 10MB. Check with your IT team. |
Most email providers cap at 20–25MB. To be safe, compress your video to under 20MB. If the video is still too large after compression, consider sharing via Google Drive, OneDrive, or Dropbox link instead.
When You Actually Need to Compress
Not every video needs compression. Here is when it actually helps.
Video over 25MB and need to send via Gmail
Gmail blocks attachments over 25MB and falls back to a Google Drive link. Compress to under 20MB to send as a direct attachment that recipients can view immediately.
Video over 20MB for Outlook
Outlook and iCloud Mail have a 20MB limit. If your video exceeds this, compress it or it will bounce back with a size error.
Sending to corporate email with 10MB limit
Many corporate Exchange servers cap attachments at 10MB. Compress aggressively — use 480p and high compression to fit within strict corporate limits.
Video under 20MB
You may not need compression at all. If your video is under 20MB, try attaching it directly — it should work with most email providers.

Why Use Diwadi for Email Video Compression
No File Uploads
Your work videos stay on your device. Screen recordings, meeting clips, and product demos never get uploaded to a random server.
No Watermarks
Compressed videos are clean — no branding, no watermarks, no logos. Professional enough to send to clients and colleagues.
No File Size Limits
Compress any video regardless of size. 500MB, 2GB, 10GB — there is no upload limit because nothing gets uploaded.
Fast Compression
Hardware-accelerated compression finishes in seconds, not minutes. Uses your computer's GPU for fast encoding.
Target Size
Set a target file size like 20MB or 10MB to match your email provider's limit. Diwadi adjusts quality automatically to hit your target.
Trim + Compress
Cut to the key moments before compressing. Trim a 5-minute screen recording to the important 30 seconds — smaller file, clearer message.
Tips for Sending Videos via Email
Try cloud links for large videos
If your video is over 25MB even after compression, upload to Google Drive, OneDrive, or Dropbox and share a link instead. Most email clients support link previews.
Trim to the key moments first
Shorter video means smaller file. Cut to the essential content before compressing — your recipients will appreciate a concise clip over a long recording.
720p is enough for email viewing
Recipients view email attachments on laptops and phones. Downscaling from 4K or 1080p to 720p saves significant space with no visible difference on screen.
MP4 with H.264 is most compatible
MP4 with H.264 encoding plays in every email client's built-in preview — Gmail, Outlook, Apple Mail. Diwadi outputs this format by default.

What is the Gmail video attachment limit?
Gmail allows attachments up to 25MB total (all files combined). If your video exceeds 25MB, Gmail will automatically offer to share it via Google Drive instead. To send as a direct attachment, compress your video to under 20MB with Diwadi.
How do I compress a video to send by email?
Open your video in Diwadi, select the medium quality preset at 720p resolution, and compress. For strict email limits (like 10MB corporate email), use high compression at 480p. Diwadi processes everything locally — your video never leaves your device.
Can I send a video over 25MB via email?
Not as a direct attachment in most email providers. Gmail, Yahoo, and ProtonMail cap at 25MB. Outlook caps at 20MB. To send larger videos, either compress with Diwadi to fit the limit, or upload to Google Drive, OneDrive, or Dropbox and share the link.
What video format is best for email attachments?
MP4 with H.264 encoding is the most compatible format. It plays directly in Gmail, Outlook, and Apple Mail preview panes. Diwadi outputs MP4 by default, so your recipients can preview the video without downloading a separate player.
How do I send a screen recording via email?
Screen recordings are often large (100MB+ for a few minutes). Open the recording in Diwadi, compress at medium quality and 720p resolution. A 5-minute 350MB screen recording typically compresses to under 18MB — well within email limits.
Does Outlook compress video attachments?
No. Outlook does not compress attachments. If your video exceeds the 20MB limit, the email will fail to send. You need to compress the video yourself before attaching it. Diwadi can compress videos to fit within Outlook's 20MB limit.
How do I reduce video size for email without losing quality?
Use Diwadi's medium quality preset (CRF 23) at 720p. On laptop and phone screens, the quality difference is minimal. For the smallest files with acceptable quality, use high compression at 480p — still clear enough for screen recordings and demos.
Can I compress multiple videos for one email?
Yes. Drag and drop multiple videos into Diwadi and compress them all. Remember that email attachment limits apply to the total size of all attachments combined — so if Gmail allows 25MB, all your videos plus any other files must total under 25MB.
What resolution should I use for email videos?
720p (1280x720) is recommended for email. Recipients typically view attachments on laptop screens or phones where 720p looks sharp. Downscaling from 4K or 1080p to 720p can reduce file size by 60-80% with no visible difference.
Is it safe to use online video compressors for work videos?
Online compressors require uploading your video to their servers. For work content like screen recordings, meeting clips, and internal demos, this could expose confidential information. Diwadi compresses locally — your videos never leave your computer.
How do I compress iPhone video for email?
Transfer the iPhone video to your Mac or PC (via AirDrop, cable, or cloud sync), then open it in Diwadi. Compress at medium quality and 720p to bring a typical 1-minute iPhone video from 120MB down to under 10MB — small enough for any email provider.
What platforms does the compressor run on?
Diwadi is a desktop application available for both macOS and Windows. It compresses videos locally using your computer's hardware — no internet connection needed. Download it free from diwadi.com.
