Shrink a PDF's file size so it fits under email or upload limits.
This tool re-renders each page as an image at a reduced quality and rebuilds the PDF from those images. It works best on PDFs made of scanned pages, photos, or graphics-heavy documents. For text-only PDFs that are already small, compression may only save a little.
Because it runs fully in your browser, larger or longer PDFs may take a little longer to process — that's normal, just let it finish.
Why is my PDF still large after compressing it?
Most PDF bloat comes from embedded images. If a PDF is mostly text with few images, there's a limit to how much smaller it can get — the file is already close to its minimum size.
Will compression affect text quality or make my PDF blurry?
Text and vector content stay sharp; compression mainly reduces the resolution and quality of embedded images, which is where nearly all the file size usually comes from.
Is this safe for confidential documents?
Yes — the PDF is processed entirely in your browser and is never uploaded to a server, so sensitive content never leaves your device.
