Common questions
Why 25 MB?+
25 MB is the attachment limit on Gmail, Outlook and many email providers. This gets a clip under it so it sends as a normal attachment instead of a cloud link.
Will it still look okay?+
25 MB is generous for short and medium clips, so quality usually stays high. We tune the bitrate to the video's length to make the most of the budget.
Is my video uploaded anywhere?+
It's uploaded over an encrypted connection, compressed on our server, and both the upload and the result are deleted after 1 hour. No account, no watermark.
What if it can't fit 25 MB?+
We give you the smallest watchable version and tell you it's just over, for a long video, trim it first.
Which formats work?+
MP4, MOV, MKV, WebM, AVI and most common video files. MP4 comes back as MP4.
