Text stays text
The default method only shrinks the pictures inside, so text stays sharp, selectable and searchable.
Compress PDF Free
Make a PDF smaller to email or upload — right in your browser, nothing is uploaded. Free.
How to compress a PDF
- Drop a PDF in, or click to choose it.
- Pick a strength. Use "Keep text" for documents, or "Pages as images" for scans when you need the smallest file.
- Press "Compress PDF" and save the smaller file.
What it can do
Great for scans
Scanned pages and phone photos are where the size is, so they shrink the most.
Smallest when needed
"Pages as images" redraws every page as a picture for the smallest possible file.
Private by design
IDs, contracts and statements stay on your device — the PDF is compressed in this browser.
Questions
Is my PDF uploaded?
No. The PDF is read and compressed only inside this browser. This page never sends it anywhere.
How much smaller will it get?
It depends on what is inside. Scans and photo-heavy PDFs often shrink a lot; PDFs that are mostly text are already small and change little.
Will the text get blurry?
Not with "Keep text" — only pictures are re-saved. With "Pages as images" the text becomes part of a picture, so pick a lighter strength if it must stay crisp.
Can I get it under a limit like 10MB?
Try Medium, then Strong, then "Pages as images". If it is still too big, split it with "Split PDF" and send it in parts.
Does it work with password-protected PDFs?
No. Remove the password in the app you use to open it first.
