How to compress a video for email (free, no upload)
Email attachments are usually capped at 25MB. Here's how to shrink a video enough to send — right in your browser, without uploading it anywhere.
Most email providers cap attachments at around 25MB — Gmail and Outlook both do. A phone video can easily be five or ten times that, so the attachment bounces. The fix is to compress the video first, and you can do it for free without installing software or handing your footage to a random website.
Why videos are so large
File size comes down to three things: resolution (a 4K clip has four times the pixels of 1080p), length, and bitrate (how much data is used per second). Lowering any of them shrinks the file. The trick is doing it without the video looking obviously worse.
The quickest way: compress in your browser
Open the compressor
Go to the Compress Video tool and drop your clip in. Nothing is uploaded — it's processed on your device.
Pick a quality preset
Start with Balanced. If the file is still too big, drop to Smallest file.
Lower the resolution if needed
For email, 720p is plenty. Capping resolution is the single biggest size saver.
Export and check the size
You'll see the before-and-after size and the percentage saved. Aim for under 25MB.
If it's still too big
- Trim the clip — do you need the whole thing? Cutting a 2-minute video to 30 seconds cuts the size by roughly 75%.
- Resize to 720p or 480p if you haven't already.
- As a last resort, upload the video to a cloud link (Drive, Dropbox) and email the link instead of the file.
Need to cut it down first? The Trim Video tool removes the parts you don't need, and Resize Video changes the resolution — both free and in-browser.
