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.
How much quality loss in Rasterize?
Depends on JPEG quality (Low=90, Medium=70, High=50). Medium is visually nearly identical to the original.
Is my file uploaded?
No. Everything runs in your browser.
How large a file?
Up to ~50MB recommended.
