Email-size video compression

Compress video to 25MB without uploading it

A 25MB target is a practical size for email-style attachment limits, support portals, and client systems. Compress locally so private footage stays on your device.

  • Useful for email and portal upload caps.
  • Target-size compression estimates bitrate from duration.
  • Footage is not uploaded to AntiUpload servers.

Why 25MB is popular

Many email and business systems have attachment limits around 20MB to 25MB. Even when a platform allows larger files, smaller videos upload faster and are easier for recipients to download.

A 25MB target is much more forgiving than 8MB, especially for short product demos, class videos, support clips, and phone recordings.

When to trim first

If a video is long, trim it before compression. Cutting dead time preserves quality because the target size is spread across fewer seconds.

For screen recordings, crop or resize only if the text remains readable. A smaller file is not useful if the viewer cannot read the screen.

No cloud copy

A video for a client, classroom, HR process, insurance claim, or support ticket can contain sensitive context. AntiUpload keeps compression in the browser so the footage does not pass through a conversion server.

How to use this workflow

  1. 01.Open the compressorChoose the video file from your device and select target-size compression.
  2. 02.Set 25MB as the goalUse 25MB as the output budget. Shorter videos will keep more visible quality than longer videos at the same size.
  3. 03.Download the attachment copySave the compressed video, check the final size, and play the file before emailing or uploading it.

Questions

Is 25MB small enough for email?
Many email systems allow attachments around 20MB to 25MB, but limits vary. Check the final file size and your email provider limit before sending.
Will 25MB ruin quality?
It depends on duration, resolution, and motion. Short clips often look good at 25MB; long 4K videos need stronger compromises.
Does the file upload?
No. Compression runs in your browser and the video is not uploaded to AntiUpload.
Should I use MP4?
MP4 is usually the safest output for email, phones, and business portals because it is widely supported.
