Find the limit
The upload question shows the allowed size and number of files (up to 10). The slider starts just under 10 MB, the most common choice — move it to 95 for a 100 MB question or 980 for 1 GB.
What fits
- 10 MB: about 30 seconds of 720p video with sound, or a few minutes of screen recording.
- 100 MB: about 4 minutes at 1080p or 10 minutes at 720p.
- 1 GB: around an hour at 720p.
Why the form asks you to sign in
Uploaded files go to the form owner’s OneDrive or SharePoint, so upload questions only work for people signed in to the same organization. That is Microsoft’s rule, not the compressor’s — compression needs no account.
Questions

Why can’t I see the upload button?
File upload works only for people signed in to the form owner’s organization. Ask the owner if you can’t sign in.
Is my video uploaded to compress it?
No. It is compressed on your device and only goes to the form when you submit it.
