Compression Mode

📝 Preserve Text (lossless cleanup)

Text, fonts, and vectors are preserved. Size reduction varies and may be small for already optimized files.

🗜️ Rasterize to JPEG (maximum)

Each page becomes a JPEG. This can reduce image-heavy files more, but text becomes an image.

⚠️ Preserve-text mode keeps content selectable but may save little space. Rasterize can reduce image-heavy files more, but text becomes an image. Compare the downloaded result with the original.

Frequently Asked Questions

Which mode should I pick?

For Word/PowerPoint/HTML exports (text-based PDFs), pick Preserve Text. For scanned documents or image-heavy PDFs, pick Rasterize for maximum compression.

Why does preserve-text not compress more?

It only removes redundant objects, restructures object streams, and strips metadata. Text and images are untouched.
