Email Attachments Hub

Stay under attachment limits without ruining quality. Compress the right file types and switch to secure links when necessary.

What this hub covers

Email providers typically cap attachments around 20–25MB. When you exceed limits, the best practice is to compress (when safe) or switch to share links with correct permissions.

Quick workflow

  1. Check total attachment size (not just one file).
  2. Compress PDFs and images first (avoid compressing already-compressed JPGs repeatedly).
  3. If you still exceed limits, share via cloud link and set “view-only” permissions.

Tools that help most

Merge / Split

Combine many small PDFs into one, or split a large PDF into parts to send separately.

Safe sharing checklist

  • Permissions: set view-only unless editing is needed.
  • Expiry: use expiring links if available.
  • Privacy: remove metadata when sharing sensitive documents.
  • File naming: use clear names and dates so recipients don’t mix versions.

FAQ

Should I zip attachments for email?

Zipping may reduce some file types, but it rarely helps JPG/MP4 and can trigger filters in some organizations. Compress the source file types instead.

Is a share link acceptable for formal submissions?

Often yes, but confirm the recipient’s policy. For official submissions, portals usually require direct upload, not email links.
