Most oversized PDFs are big for one reason: images. A scanned contract at 300 DPI can weigh 2 MB per page, while the text in it is almost nothing. Email systems cap attachments around 20–25 MB and many portals at 2–5 MB, so a 40-page scan is stuck until it is recompressed.
The practical fix is to re-render each page at a sensible resolution (110–200 DPI) and store it as an optimized JPEG inside a fresh PDF. That is what the compressor below does, entirely in your browser. The trade-off is honest: pages become images, so text is no longer selectable. For scans — the case that is actually too big — nothing is lost visually at the balanced setting.
How to do it in 3 steps
- Open the faymox PDF Compressor and pick Balanced (Smallest file for strict limits).
- Drop your PDF — each page is recompressed on your device; nothing is uploaded.
- Compare the before/after sizes and download the smaller PDF.
FAQ
Why is my compressed PDF text not selectable?
The pages are rebuilt from rendered images. Keep the original if you need searchable, selectable text — or use this for scans, where pages are images already.
What is a good size for email?
Under 10 MB is safe almost everywhere; under 5 MB passes most portals. The Smallest file preset (110 DPI) is made for strict limits.
Is it safe for contracts and statements?
The file never leaves your device — compression runs in your browser tab, so private documents are not sent to any server.
