Compress PDF

Two ways to make a PDF smaller. Basic re-save strips leftover data and keeps the text selectable. Strong compression rebuilds every page as a compressed image — the biggest savings for scanned PDFs and photo documents (pages become images, so the text is no longer selectable). A smaller size is never promised — the result always shows the real before/after size.

What: Makes a PDF file smaller, right in your browser — nothing is uploaded anywhere. How: Choose a PDF, pick a mode (Strong for scanned files), press Compress, and check the real new size shown.

Make a PDF smaller with a basic re-save or strong image compression for scanned files, and clearly see the real before/after size — free, in your browser; your file is never uploaded anywhere.
