Compress PDF for Email Attachment

Most email providers reject attachments over 20-25 MB. Compress your PDF locally to fit any inbox — no quality loss, no upload, no privacy risk.

Why use a browser-based tool?

Email providers like Gmail (25 MB), Outlook (20 MB), and Yahoo (25 MB) have strict attachment limits. A scanned contract, a design portfolio, or a multi-page report can easily exceed these limits. Our PDF Compress tool reduces file size by 30-70% through local browser-based optimization — your document never leaves your device, making it safe for confidential business files, legal contracts, and personal records.

How it works

1. Upload your PDF — drag and drop into the tool.
2. Automatic compression — the tool optimizes images and removes redundant data.
3. Download and attach — your compressed PDF fits any email provider's limits.
