How to compress a PDF
- Drop in (or browse for) your PDF.
- Pick a quality level — Strong for the smallest file, Light for the best quality.
- Click Compress PDF, check the size saved, and download.
How does it work?
Each page is rendered to an image and re-encoded at your chosen quality, then rebuilt into a new PDF. This works best on scanned or image-heavy documents. Because pages become images, the text is no longer selectable — if you need selectable text, keep your original.
FAQ
My PDF didn’t get smaller — why? Text-only PDFs are already very compact, so rasterising them can’t shrink them further. This tool shines on scanned pages and photo-heavy files.
Is it private? Yes — compression happens entirely in your browser; nothing is uploaded or stored.
