Email bouncing because your PDF is too large? Here are five approaches, from simplest to most aggressive.
1. Remove Embedded Fonts
Fonts can add 500KB-2MB per font. Use standard fonts (Arial, Times, Helvetica) when possible.
2. Downscale Images
A PDF with 300dpi images for screen viewing is overkill. 150dpi is plenty for on-screen reading; 72dpi for web distribution.
3. Remove Metadata
Edit history, thumbnail previews, and internal bookmarks add up. Stripping metadata can save 5-15% of file size.
4. Flatten Transparency
Overlapping transparent layers multiply file size. Flattening merges them into single layers.
5. Use Our AI Compressor
Our PDF compressor applies all of these techniques intelligently. It knows which elements can be compressed more and which need to stay high-quality. Try compressing to under 1MB for email-friendly results.
