About this tool
Reduce a PDF's file size — ideal for email attachments or upload limits — with a choice of compression levels.
Frequently asked questions
How much smaller will my PDF get?
It depends heavily on content — image-heavy PDFs (scans, photo-filled documents) often shrink by 50% or more, while mostly-text PDFs compress much less since text is already compact.
Will compression make my PDF blurry?
There's a genuine trade-off between file size and image quality inside the PDF — pick a lighter compression level if the document has images you need to stay crisp, or a stronger level if file size matters more.
Does this work on scanned/image-based PDFs?
Yes — those actually compress the best, since the compression primarily targets the embedded images.
