Compress video for Gmail attachments
Use this tool to compress video for Gmail when an MP4, MOV, or WebM is too large to attach or share by email.
Start near 24 MB, preview the result, and switch to Drive when the video needs more quality.
Compress video
The video compressor creates a new MP4 download.
Pick the approximate maximum size you want. Compress by percentage or MB; the two fields stay linked.
Compress video with no server upload
The compressor reads the selected MP4 on your device, so private videos do not leave your browser.
Compress by percentage or target MB
Choose roughly how small the MP4 should be. The compressor accepts smaller results instead of chasing an exact file size.
Compress after caching
Open the site once, then the app shell and video engine can be reused when your connection is gone.

Why compress video for Gmail below 25 MB?
Gmail is not meant to be a large-video attachment store. If you need a normal attachment, compress video for Gmail near 24 MB; if the video needs more quality or your account allows more, a Drive link is often cleaner.
Personal Gmail commonly uses 25 MB
Google Help says personal Gmail accounts have a 25 MB attachment limit. When you compress video for Gmail, 24 MB is a safer direct-attachment target.
Oversized files usually become Drive links
The same official Gmail help says files over the total attachment limit are removed as attachments and added to the email as Google Drive links.
Some Workspace limits can differ
Workspace admins can set attachment limits, and Google has announced 50 MB attachments for Enterprise Plus, so check your account before you compress video for Gmail.
Compress video for Gmail with a practical size target
A useful compress video for Gmail workflow starts with the file you have, aims below the attachment limit, and gives you a smaller MP4 download. Compress video for Gmail again with a lower target only when the first result is still too large.

How to compress video for Gmail
Compress video for Gmail in four short steps: choose the oversized video, keep the target below the limit, run compression, then download the smaller MP4. You can compress video for Gmail again with a different target before sending.
Choose the video Gmail cannot attach
Open the compress video for Gmail tool, select your MP4, MOV, or WebM, and check the original file size before starting.
Start below the 25 MB Gmail limit
Compress video for Gmail from the 24 MB preset when you need a standard attachment. Use a smaller target if your recipient has stricter email limits.
Compress and compare the result
Run the compress video for Gmail tool, then compare the original size, output size, and reduction before downloading.
Attach the smaller MP4 or use Drive
Download the result from the compress video for Gmail tool. If the video still needs to be larger than the attachment limit, send a Google Drive link instead.
When to compress video for Gmail or use Drive
Compress video for Gmail under 25 MB
Compress video for Gmail to 24 MB or less when you want a normal personal Gmail attachment and do not want Gmail to replace it with a Drive link.
Use Drive for longer videos
Compress video for Gmail only when a direct attachment matters. For long, high-resolution, or important quality videos, compress video for Gmail as a quick test, then use a Drive link when quality needs more space.
Check work or school accounts
Compress video for Gmail with your account rules in mind because Workspace admins and Google plan changes can set different sending limits. If your organization allows more, compress video for Gmail to that current target instead.
