Why Pre-Compressing Matters
Gmail, Microsoft Outlook, Yahoo Mail, and Apple Mail bounce email attachments exceeding 20MB–25MB. Uploading to Google Drive or Dropbox creates sharing permission hurdles for clients. VideoReduce compresses corporate presentations, webinars, and camera clips down to under 20MB so you can attach them directly to any email message.
