Find the limit
Under the upload question Google Forms shows “Max 10 MB” (or another size). The slider starts just under 10 MB, the most common choice — move it under 100 MB or 1 GB if the form allows more.
What fits
- 10 MB: about a minute of 720p video with sound, or a few minutes of screen recording.
- 100 MB: 10+ minutes of 720p video.
- 1 MB: only a few seconds — trim the clip first (Advanced settings → Trim, split & name).
Why the upload asks for Google sign-in
File upload questions save files to the form owner’s Google Drive, so Google asks respondents to sign in. That is part of Google Forms, not of the compressor — compression itself needs no account.
Questions
What is the Google Forms upload limit?
The form owner sets it per question: 1 MB, 10 MB, 100 MB, 1 GB or 10 GB. The question shows which one.
Why can’t I upload my video to a Google Form?
It is bigger than the question’s limit, or the form owner’s Drive is full. Compress the video under the shown size.
Is my video uploaded to compress it?
No. Compression runs in your browser; the video only goes to the form when you submit it.
