Email attachments are fine for small files. For anything large, sharing via link is cleaner — no size limits, recipients always get the latest version, and you can revoke access if needed.
What's actually going wrong
Attachments have limits: file size, server policies, version control. Once attached, the file exists in every recipient's mailbox forever, even after you realise you sent the wrong version.
Links solve these. The file lives in cloud storage; the link is a reference. Update the file, the link still points to the current version. Revoke the link, access is gone.
The quick fix
Upload the PDF to your cloud service (Google Drive, OneDrive, Dropbox, iCloud). Get the share link. Set permissions — 'anyone with the link' for broad access, 'specific people' for tighter control.
Email or message the link instead of attaching.
For an even simpler route: services like WeTransfer let you upload and share without an account or recipient signup.
If that didn't work
If recipient organisations block cloud links, you may need to attach despite the friction. Compress first, attach, accept the limitations.
For highly sensitive content, ensure the cloud service supports access logging and revocable links. Enterprise tools (SharePoint, Box) offer this; consumer services less so.
Prevent it next time
Default to link sharing for files over 5MB. Set up your cloud workflow once and use consistently. Verify recipients can access links before relying on them for critical communications.
FAQ
Is link sharing as professional as attachments?
Yes — increasingly the standard in business. Many enterprises prefer links for security and version control. Casual or formal contexts both accept links.
Can recipients download the file from a link?
Yes — clicking the link opens the PDF in a preview, and a download button is usually present. Recipients get the file just like an attachment.
What if I want to update the PDF after sharing?
That's the advantage of links. Update the file in cloud storage; the link points to the latest version. Recipients always see current content.
Are shared links secure?
Depends on permissions. 'Anyone with the link' is roughly as secure as a long random URL — practically secret but not enforced. 'Specific people' requires recipient authentication.
Link sharing solves attachment problems. Upload to cloud, share the link, control access. Flint helps you prepare PDFs for sharing.
