Good to know
A PDF is almost always heavy because of its images: high-resolution photos, scanned pages. The tool brings each image down to the resolution actually useful for the page size, re-encodes it with MozJPEG, then reorganizes the file structure. Text and vector graphics are left untouched. If the file is already optimized, we give you back the original rather than a larger file.
Compress PDF: frequently asked questions
Why did my PDF barely shrink?
A text-only PDF is already very compact, with no images to optimize. Savings are large on scanned or illustrated documents.
Which level should I choose?
“Recommended” suits screens and office printing. “Strong” shrinks further, for email. “Light” keeps high print quality.
