Frequently Asked Questions
Why does Gmail force videos into Google Drive links?
Gmail has a hard 25MB attachment limit. Any file over 25MB is automatically converted into a Google Drive link. ClipShrink reduces your video to ~22.8MB so it attaches directly as an inline file.
Does this 25MB compression work for Outlook and Apple Mail as well?
Yes. Outlook and Apple Mail enforce 20MB–25MB limits. Our 25MB preset ensures seamless direct emailing across all standard email clients.
Will work presentations and screen recordings remain readable at 25MB?
Yes. 25MB provides ample data budget. Screen recordings and presentation videos up to 10 minutes remain crisp and text stays completely legible.
