Compress PDF for Email Attachments
Compress PDFs for email — shrink large documents to under 5MB, 10MB, or 25MB so they fit Gmail, Outlook, and corporate mail server attachment limits.
Why teams use Compress PDF for Email
Email systems enforce attachment limits — Gmail's 25MB, Outlook's 20MB (often lower in corporate environments), HMRC's 5MB. This tool compresses your PDF to a target size you specify, using a profile tuned for email delivery: images are recompressed to a screen-readable resolution, text stays vector-sharp, and metadata bloat is stripped. The result is a smaller PDF that's still perfectly readable and looks the same on screen.
Choose your target — 1MB, 2MB, 5MB, 10MB, or custom — and the compressor picks the optimum settings to hit it. If the target is impossible without unacceptable quality loss, the tool tells you upfront so you can either accept a larger file or split the document instead. Vector content (text, charts, diagrams) is never resampled, only embedded raster images, so reports with mostly text barely change in size or quality.
Used for sending HMRC submissions, attaching financial reports to investor emails, returning signed contracts, distributing client deliverables, and any workflow where the email size limit is the blocker. Files run over TLS, are deleted within an hour, and never logged.
