Compress PDF

About Compress PDF

Scanned pages, embedded photos and unoptimized resources make PDFs balloon far beyond email and portal limits. This tool re-encodes the document on the server - pick Strong for the smallest file, Recommended for a balance, or Low for the best quality. An honest guarantee: if compression would make the file larger, you get the original back instead.

How Compress PDF works

1. Upload your PDF.
2. Choose a compression level - Strong, Recommended or Low.
3. Click Compress PDF and compare the reported sizes.
4. Download the smaller file.

Features

• Three compression levels, from quality-first to smallest-file
• Re-encodes embedded images and removes redundant data
• Never returns a result bigger than the original
• Shows exactly how much space was saved

Tips for best results

• Scanned documents compress far more when scanned in Grayscale or B&W - re-scan in that mode if colour is not needed.
• Send only the pages that matter: Extract PDF Pages before compressing can cut the size by more than any compression level.
• Always open the compressed file once and zoom into a page with small text or a photo to confirm it still looks right.

FAQ

How much smaller will my PDF get?

It depends on what is inside. Scans and image-heavy PDFs often shrink dramatically; already-optimized files may barely change - there is no redundant data left to remove.

Will text stay readable?

Text stored as real text is untouched. Compression targets embedded images; at Strong level those images are re-encoded more aggressively, so zoom in on a photo-heavy page if quality is critical.

Which level should I pick?

Start with Recommended. If the file still exceeds your limit, try Strong. Use Low when quality matters more than size.
