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