03 / Questions
Frequently, clearly answered.
01Will the text become blurry?+
No — text remains vector and crisp. We compress images to ~150 DPI which is invisible on most displays.
02How much smaller does it get?+
Image-heavy PDFs typically drop 40–80%. Text-only PDFs see smaller gains since they're already efficient.
03Is the file private?+
Always. We delete uploads and outputs after 30 minutes.
