FAQ
Frequently asked questions
How does PDF compression work?
Drefly re-encodes embedded images at a lower quality and resolution, then rebuilds the PDF with optimized internal structure.
Which compression level should I use?
Low keeps the most quality with modest savings, Medium balances size and quality, and High gives the smallest file for text-heavy documents.
Will compression affect text quality?
Text and vector content stay sharp - only embedded raster images are recompressed, so scanned pages shrink more than text-based PDFs.
Is compressing a PDF free?
Yes, compressing a PDF is completely free with no signup and no limit on file size.
Which compression level should I pick?
Use light compression to keep quality nearly identical, medium for a good balance, or strong when file size matters most, like email attachment limits.
