Zoom cloud and local recordings can be enormous — a 1-hour meeting at 1080p can produce a 2–4 GB MP4. Compressing Zoom recordings to H.264 MP4 at 720p typically reduces file size by 70–90% while keeping the video perfectly watchable for review or archival. This tool is also useful for preparing short video clips to share in a Zoom session — smaller files load faster when screen-shared or sent via Zoom chat.
Try a Zoom-ready H264 MP4 encode at 720p. Create a free account for up to 8K/120fps and production workflows.
Locate your Zoom recording (local recordings save to ~/Documents/Zoom, cloud recordings download from zoom.us). Upload the MP4 above and convert to H.264 at 720p. A 1-hour recording typically compresses from 3–5 GB down to 300–600 MB.
Local recordings save as MP4 (video), M4A (audio only), and CC.VTT (captions). Cloud recordings are MP4 with AAC audio. All are already H.264 but at a higher bitrate — compressing reduces storage and sharing size.
Zoom chat allows file attachments up to 512 MB. For shorter clips or screen share recordings, compressing to H.264 720p keeps most videos well under this limit.
At 720p H.264, screen content and faces remain clear for typical meeting review purposes. Slides and text are readable. If you need pixel-perfect slides, keep at 1080p — the file will be larger but all text will be crisp.
Compress the MP4 with this tool, then share via Google Drive, Dropbox, or email (if under 25 MB). For Zoom-hosted cloud recordings, use Zoom's built-in sharing link which streams without requiring a download.
The public encoder is useful for quick previews. For larger files, up to 8K/120fps output, bulk jobs, API access, storage outputs, and webhooks, create an account and run production workflows with predictable NEU estimates.
