Compress a PDF,
for free.

Scanned documents and PDFs built from full-resolution photos are the most common reason a "few page" PDF ends up 10-20MB. This tool re-renders each page at a sensible print resolution and recompresses it, which usually cuts the file down dramatically with no visible difference at normal reading zoom.

How it works

Upload your PDF. Works best on scanned documents or PDFs assembled from photos — those are almost always where the size problem lives.
Set the quality. 75% is a good default for anything that will mainly be read on screen or emailed. Drop it lower (50-60%) for maximum size reduction, or raise it (85%+) if the PDF has fine print or detailed images that need to stay sharp.
Compress. Each page is re-rendered at a print-appropriate resolution and recompressed, then reassembled into one file that downloads automatically.

Common questions

Will this make text blurry?

At the default settings, text stays legible at normal reading zoom — the compression targets a resolution well above what's needed for on-screen or standard printing. If you zoom in far past 100%, some softening becomes visible, which is the trade-off for the smaller file.

Does this keep the text selectable/searchable?

No — this tool rebuilds the PDF from rendered page images, the same way most "compress PDF" tools work. If your original PDF had selectable text and that matters for your use case, keep the original alongside the compressed copy.

My PDF is already small. What happens if I run it through anyway?

If a PDF is already efficiently compressed (text-only, no big embedded images), this process won't shrink it much further, and rebuilding from rendered images could occasionally make an already-tiny, text-only PDF slightly larger. It's built for the common case: PDFs bloated by scans or embedded photos.
