A sensible place to start
Use 24MB for services with a 25MB limit, or 9.5MB when the recipient's system is unknown.
The compressor above is preconfigured for this use case. Actual results still depend on the source codec, motion and detail.
Why it works
Spend fewer bits, deliberately
Mail providers count attachments differently and may encode them during delivery. Leaving a safety margin makes a rejected message less likely.
Three simple steps

Frequently asked questions
Is email video compression private?
Yes. Standard compression runs inside your browser. The video file is not sent to a VideoShrink server.
Will the output size be exact?
Target-size mode aims slightly below your limit, but container overhead and unusual source files can make the final size vary.
Why can compression take a while?
Encoding is demanding work. Duration, resolution, device speed and browser memory all affect processing time.
Make your video easier to share
Private browser compression. No account required.
